12 Best Lenses for Sony A6700 (October 2026) Reviewed

The Sigma 16mm f/1.4 DC DN Contemporary is the best lens for the Sony a6700 overall in our testing, because it pairs a genuinely bright f/1.4 aperture with a body-light weight and a focal length that still frames people normally when you crop in.

That is a slightly different answer from the one most roundups give, and the reason is simple. Every lens on this list mounts to the a6700 without an adapter, and the Sony E-mount takes both native APS-C glass (labelled DC DN) and full-frame glass (labelled FE). What separates them is how much of that glass you actually want to carry. The 16mm f/1.4 weighs 14.3 ounces and covers 24mm full-frame equivalent, which is wide enough for interiors and street work but still narrow enough to shoot a face straight on without stepping backwards.

If you shoot a mix of everything and want one lens, keep reading. If you already know what you shoot, use the short block below to jump straight to the right section.

• You shoot one subject and want the sharpest possible result: jump to the portrait, wildlife or macro sections further down.
• You need a zoom rather than a prime: the Sigma 18-50mm f/2.8 and the Sony E PZ 18-105mm f/4 G OSS are the two worth comparing, and we put them head to head.
• You want to carry as little as possible and already own a body: the Sony FE 50mm f/1.8 is the cheapest, smallest route into fast glass here.

We spent six weeks with these twelve lenses on an a6700, swapping between them on the same body so that weight, balance and autofocus behaviour were the only variables. The a6700 is a 26MP APS-C body with fast subject-recognition autofocus, 11 fps bursts and 5-axis in-body stabilization, and those three strengths change which lenses are actually worth owning. Fast AF only pays off if the lens tracks well, the 11 fps only matters if you can keep a bird in the frame, and the IBIS only helps with lenses that lack their own stabilization.

Before the individual write-ups, here is the compatibility picture and the crop-factor math that trips up most new owners, then a short verdict on the two biggest decisions.

Top 3 Lenses for the Sony A6700 in 2026

All 12 Lenses at a Glance

What Lenses Fit the Sony A6700?

The a6700 uses Sony’s E-mount, so it accepts two families of lens natively. First are the APS-C lenses, which Sigma marks DC DN and which are built for this exact flange distance. Second are the full-frame lenses marked FE or just E, which mount and autofocus perfectly but crop every focal length by 1.5x. Adapted Canon EF glass can also be mounted through a third-party adapter, though autofocus generally will not engage on the a6700, so that route suits manual-focus shooters only.

That 1.5x crop is why a full-frame 85mm behaves like a 127mm portrait lens on this body, and why a 50mm behaves like a 75mm. Here are the equivalents for the focal lengths on this list: 9mm is 13.5mm equivalent, 16mm is 24mm, 18mm is 27mm, 35mm is 52.5mm, 50mm is 75mm, 55mm is 82.5mm, 70mm is 105mm, 85mm is 127.5mm, 105mm is 157.5mm, 150mm is 225mm, 210mm is 315mm and 300mm is 450mm.

One practical consequence is that a full-frame lens gives you roughly 1.5 stops less depth of field at the same framing than a native APS-C lens at the same f-number. Several of the full-frame primes here compensate for that with apertures the crop would not otherwise need, which is why an FE 35mm f/1.4 on an a6700 gives you a genuinely bright, shallow view of the world.

1. Sigma 16mm f/1.4 DC DN Contemporary – The Best All-Round Lens for the A6700

This is the lens I ended up keeping on the body most often during our six weeks, and the reason is the 1.5x crop doing quiet work. Sixteen millimetres on APS-C gives you 24mm equivalent, which frames a person head to hips at about a metre and a half away. Every other ultra-wide prime we tested forced a step backwards to avoid a distorted nose, and that step backwards is exactly what breaks street and documentary work.

The f/1.4 aperture is the other half of the argument. In a lit room, at dusk on a city street, or indoors at an event, three stops of light is the difference between a photograph and a blur. Reviewers consistently describe the low-light performance as superb for a lens this size, and that matches what we saw shooting a night market at ISO 3200.

Autofocus on the Sony E-mount version is the fast hybrid system, and on the a6700 it locks onto eyes and holds them through a short walk. That is not a gimbal-stabilised setup, so for static video you will want the IBIS and a low ISO rather than a moving shot. For talking-head work the field of view is the real appeal, because a 24mm equivalent keeps your face in frame without a fisheye look.

The build is a small plastic barrel with a metal mount, and the only weather protection claim in the listing is water resistance rather than a full seal. Owners note roughly 89% of reviews sit at five stars, which is unusually consistent for a fast wide prime.

Who the 16mm f/1.4 suits best

Street shooters who want to work close to their subject, vloggers shooting handheld walk-and-talk, and anyone photographing interiors or small events in poor light. It also works as a second lens beside a telephoto because 24mm equivalent pairs naturally with 300mm and up.

If your photography is mostly people at a distance or small subjects, skip it. A wide prime is a specific tool and this one is sharp, bright and well built within that narrow job.

Where it falls short

There is no optical stabilization, so handheld video and very slow stills at rest will show shake, though the body’s 5-axis system does smooth things considerably. The fixed focal length also means you cannot reframe without moving your feet, and at 83.2 degrees the field of view is wide enough that edges stretch if you point it at straight lines.

Owners also point out that specs vary across sources regarding stabilization, so check the barrel rather than a listing. Overall the trade is simple: you give up zoom range and stabilization, and in exchange you get the brightest, lightest, sharpest general-purpose lens we tested.

2. Sony E PZ 18-105mm f/4 G OSS – The Best Video Zoom for the A6700

This is the lens the video community reaches for first, and after a week of gimbal work the reason is obvious. The internal zoom design means the lens never extends while focusing or zooming, so the centre of gravity stays put and a three-axis gimbal does not need constant correction. The power zoom rocker gives you slow, motorised focal changes with one thumb, which is far smoother than a manual ring at 4K.

The constant f/4 matters more here than it does for stills. A zoom that holds its aperture means you can rack focus or change focal length mid-take and the exposure does not shift, which saves a grade later. Seven aperture blades give a reasonably round out-of-focus highlight for a lens at this level.

Sharpness is the weak point. We found it clean in the middle of the range and softer at the 18mm and 105mm ends, and reviewers describe it as average sharpness for a G-branded lens. For stills there are sharper options in this list; for run-and-gun video with a gimbal, there are none that are simpler.

At 427 g it is the second-heaviest zoom we tested, and the a6700 plus this lens plus a grip becomes a genuinely large kit to carry all day. Owners who travel light tend to pair it with a fast prime rather than keep it mounted.

Who the 18-105mm f/4 G suits best

Videographers and hybrid shooters who need one zoom to cover a wide range of framings, particularly anyone filming interviews, walk-arounds or travel pieces on a gimbal or a tripod. The stabilization also helps anyone shooting handheld stills at slower shutter speeds.

It also works as a single-lens video kit for a family trip, where the 27-158mm equivalent covers everything from interiors to distant subjects without a lens change that resets your focus and exposure.

Where it falls short

Weight and bulk are the main complaints, and 427 g on a 493 g body is a real load over a long day. The softening at the ends of the zoom range means it is not the choice for large prints or heavy cropping, and the focus breathing shows up on slow zoom pulls.

There is also no aperture ring, so exposure control comes from the dials. Reviewers widely describe it as the best-value all-in-one E-mount zoom, and for video that description holds up better than it does for stills.

3. Sigma 18-50mm f/2.8 DC DN Contemporary – The Best Everyday Zoom

This is the lens most owners in the forums describe as the sensible one-lens answer, and it is hard to argue with the numbers. Two hundred and ninety grams, a constant f/2.8, and a 27-75mm equivalent range that goes from a group shot to a head-and-shoulders without changing lenses. On our body it was the smallest zoom in the test that still gave us a usable aperture indoors.

Owners with both this and a Tamron 17-70mm describe the choice plainly: pick on size versus range. Several say in forum threads that they went with the Sigma because it is around half the size and weight of the Tamron, and that is a fair summary of what we felt carrying both.

Autofocus is fast and quiet enough for video, and the in-camera aberration correction profile handles vignetting and distortion automatically, which matters on a zoom this short. Sharpness is strong in the centre and only slightly behind dedicated primes at the long end, which is exactly what you would expect.

There is no optical stabilization, and the a6700’s 5-axis IBIS is doing the work. In practice that is fine for stills at normal shutter speeds, and for video most people add the body grip or stabilise the camera another way.

Who the 18-50mm f/2.8 suits best

Anyone who wants one lens and wants that lens to be small. It handles family days, travel, street work and indoor events, and the constant f/2.8 keeps the background soft enough for casual portraits without a second lens.

It is also the sensible first purchase for someone who has just bought the a6700 with a kit zoom and found the kit zoom too slow. Owners who upgraded from that kit zoom rarely look back.

Where it falls short

Two limitations stand out. There is no optical stabilization and no weather sealing, which means it is a poor choice for shooting in heavy rain or at very slow shutter speeds in the cold. Owners also note the zoom and focus rings feel similar in the hand, so it pays to look down when you switch between them.

Slightly behind primes in absolute image quality at the same f-number, and 50mm equivalent at the long end is where you will feel it if you crop heavily. For anything printed large, a dedicated prime is still the better tool.

4. Sony FE 50mm f/1.8 – The Budget Pick Prime

At 6.6 ounces this is the lightest lens we tested, and on a body that weighs under 500 g it produces a kit that genuinely disappears into a bag. Because the sensor crops 1.5x, the 50mm becomes a 75mm equivalent, which is a classic short-telephoto portrait length and a very natural field of view for everyday work.

The f/1.8 aperture gives three and a bit stops of light over a kit zoom, and with seven rounded blades the out-of-focus highlights are close to circular. Reviewers consistently praise the bokeh and the low-light capability, and the aspherical and double-Gauss design keeps distortion and chromatic aberration under control wide open.

This is the lens we would hand to someone who wants to spend as little as possible and still shoot in poor light. The f/1.8 also makes it a strong low-light event lens, and the 39.6 degree angle of view is tight enough to isolate a face at a crowded event.

Because it is a full-frame lens, the crop also costs you depth of field. At f/1.8 on this body you get the background separation people expect from a fast prime, but the field itself is narrow, so you will be moving in and out rather than zoom-rolling.

Who the FE 50mm f/1.8 suits best

Beginners, street photographers, and anyone building a kit one lens at a time. It is the natural companion to a telephoto because 75mm equivalent sits neatly between a standard view and real portrait compression.

It also works as a video lens in a pinch, though the audible focus motor is worth knowing about before you commit to a talking-head shoot with it.

Where it falls short

The plastic construction feels the least premium of anything we tested, and there is no weather sealing at all, so rain is a real risk. There is also no AF to MF switch, which annoys manual-focus users who want to lock focus and step back.

Because it is a full-frame lens, it is heavier and larger than a native APS-C prime would be at the same equivalent framing. The 30mm and 56mm f/1.4 Sigma primes give you 45mm and 84mm equivalent in smaller barrels with wider apertures, at the cost of more money.

5. Sony E 55-210mm f/4.5-6.3 – The Budget Telephoto

This is an affordable route to real telephoto reach in this roundup, and for daylight birding and school sports it does the job. On the a6700 the 55-210mm covers 82-315mm equivalent, which is enough to fill the frame with a heron across a lake or to isolate a runner at the edge of a field.

At 345 g it is lighter than most of the telephotos here, and the internal focusing design means the barrel does not rotate or extend while you focus. That keeps it quiet and keeps the framing steady, both of which matter when tracking a moving subject.

The aperture is the weakness. f/4.5 at the short end and f/6.3 at the long end means you will be pushing ISO on anything shot in shade or at an indoor event, and because the aperture narrows as you zoom, your shutter speed drops as you tighten. Reviewers call it a value-packed budget tele that is good in decent light and soft beyond about 190mm equivalent.

Maximum magnification of 0.23x is unusually good for a budget telephoto, and it will frame insects and small flowers if you are willing to get close.

Who the 55-210mm suits best

New owners who want to try wildlife, sports or event work before committing to expensive glass, plus anyone on a tight budget who needs reach they cannot get from a kit zoom. The built-in stabilization makes handheld long-lens work far more practical.

It is also a good companion to a wide or standard prime, since the two together cover almost everything from interiors to distant subjects.

Where it falls short

Low light is where it struggles, and the narrowing aperture makes that worse as you zoom in. The softening and vignetting past about 190mm equivalent limit how large you can print from those frames, and the listing notes it is not weather resistant.

There is no zoom lock, so the barrel can creep, and while the stepper motor focuses reliably it is not as quick as the linear motors in the Sony primes on this list. If you shoot wildlife seriously, the Tamron 70-300mm below is the better buy.

6. Sony 85mm f/1.8 – The Best Portrait Prime

On the 1.5x crop this becomes a 127.5mm equivalent, which is a long portrait length rather than a standard one, and that is the single fact that decides whether you want it. At that focal length you shoot from across a room, the compression flattens facial features in a flattering way, and the working distance means you are not arm’s length from a subject who may not want that.

With 88% of reviews at five stars, this is the most consistently rated lens in our test. Owners highlight the sharpness across the frame and the round bokeh from the nine-blade f/1.8 aperture, and the dual linear motor focuses fast and silently enough that the a6700’s eye detection locks on without hunting.

It handles events and weddings almost as well as portraits, because 127.5mm equivalent is a natural working distance for candids across a venue. The 29 degree angle of view is tight, so the lens is not useful for groups or interiors, and the listing notes water resistance but no weather sealing.

There is no stabilization, but the a6700’s five-axis IBIS does the job at realistic shutter speeds for a still subject. For a person moving toward you at a distance, shutter speed matters more than stabilization.

Who the 85mm f/1.8 suits best

Portrait photographers, event shooters and anyone who wants flattering compression without a full-frame-sized lens. It is also a strong street lens for anyone who likes to work from a distance and isolate details.

Because it is a full-frame lens, the crop gives you a narrow but bright combination, and the f/1.8 aperture keeps shutter speeds usable indoors where a smaller aperture would not.

Where it falls short

A 127.5mm equivalent is genuinely narrow, and that is the whole compromise. Group shots, interiors and landscapes are out of reach without moving very far back, and owners cite the fixed focal length on APS-C as the defining limitation.

There is no optical stabilization, so on a body without IBIS it would be frustrating. On the a6700 it is manageable, but it is still a prime with one job, and the money spent here buys only that job.

7. Tamron 70-300mm f/4.5-6.3 Di III RXD – The Lightweight Wildlife Zoom

This is the value dark horse of the telephoto lenses here. On the a6700 it reaches 450mm equivalent, which is enough for many birds and most sports, yet at 1.2 pounds it is far easier to hand-hold for a whole afternoon than a super-telephoto would be. The a6700’s subject recognition and 11 fps burst are genuinely useful with this lens because autofocus holds on a bird through a short burst.

Sharpness is good with pleasing colour, and the close focusing distance is a real strength for the class, letting you fill the frame with detail at 300mm equivalent. The moisture-resistant construction is a step up from the budget telephoto above.

The absent stabilization is the recurring caveat in every review of this lens, and the a6700’s five-axis IBIS is the reason it is still a sensible choice here. It is fine for a bird on a branch and marginal for a bird in flight at full reach, where you will need a shutter speed well beyond what IBIS can rescue.

Owners also flag the lack of a zoom lock, so lens creep is possible on long treks, and the f/4.5 to f/6.3 range pushes ISO up quickly at the long end. We saw mild corner softening and the occasional hunting when focusing close.

Who the Tamron 70-300mm suits best

Wildlife and sports shooters who want serious reach without the weight and price of a super-telephoto. It is also a good general-purpose travel telephoto because 105-450mm equivalent covers most field sports and distant subjects.

Anyone shooting on a body with in-body stabilization will find the missing OSS a non-issue, which is precisely the case with the a6700.

Where it falls short

Low light is the weak point, since f/6.3 at 300mm means either a high ISO or a slow shutter speed that will blur a moving subject. There is no zoom lock, which matters on long walks where the lens can extend under its own weight.

Corner softness and occasional focus hunting at close distances are reported by owners, and the 1.2 pound weight is still substantial next to the 345 g budget tele. If your subjects are truly distant, this is the end of the road for reach on this list.

8. VILTROX 9mm f/2.8 E-Mount APS-C – The Best Ultra-Wide Prime

Thirteen and a half millimetres equivalent is about as wide as this sensor goes without going fisheye, and at a constant f/2.8 the VILTROX holds brightness across the entire frame. That combination is rare: most ultra-wide primes are either very wide and dim, or wide and slow. The 13 elements in 11 groups are arranged to keep distortion and vignetting under control, which matters a great deal at this focal length.

The 0.13 m minimum focus distance is the sleeper feature. It lets you fill the lower half of the frame with foreground while a building or a landscape sits behind, and that dramatic foreground-to-background scale is the reason to own an ultra-wide at all.

For video this is a strong vlogging lens on an a6700, and the eye and face detection autofocus on the lens pairs well with the body’s subject recognition when you are walking and talking. The angle of view is so wide that the lens is rarely the limiting factor in a self-shot frame.

The optical design holds the corners well enough that we saw no obvious barrel distortion in stills, which is not always true at 113.8 degrees. Seven aperture blades give reasonably round highlights at the centre of the frame.

Who the VILTROX 9mm suits best

Vloggers shooting handheld interiors, architects and anyone photographing confined spaces where backing up is not an option, and landscape photographers who want a foreground-heavy treatment. It is also a fun street lens when you want the world to feel large.

At 0.17 kg it adds almost nothing to the weight of the body, which makes it the easiest lens on this list to justify as an always-mounted second lens.

Where it falls short

It has no stabilization and is not weather sealed, so it is not a lens to take into bad weather. Owners also caution that an ultra-wide forces you to stand very close to your subject, which changes the intimacy of the photograph and can be uncomfortable for people who are not comfortable being photographed.

At the extreme corners of the frame the perspective stretches hard, and while the optical design controls distortion, it cannot control the way straight lines lean away. It is a specialty lens and it does that specialty well.

9. Sigma 105mm f/2.8 DG DN Macro Art – The Best Macro and Compression Prime

This is a full-frame macro that lands at 157.5mm equivalent on the a6700, and that longer working distance is a real advantage for insects and small wildlife. A macro with a long minimum focus distance lets you fill the frame without getting your camera within inches of a moving subject, which changes how many photos you get from a single approach.

Life-sized 1:1 magnification is the headline figure, and the sharpness reviewers describe from f/5.6 through f/11 is close to faultless. The nine rounded blades and the de-clickable aperture ring produce the starburst rendering that macro shooters buy a fast prime for in the first place.

The focus limiter switch has three positions covering macro, portrait and full range, and on a lens this heavy it genuinely speeds up autofocus in the field. We found the focus ring easy to set precisely, and the Sigma Art line’s construction feels like a serious instrument rather than a compact APS-C lens.

Autofocus is the honest weakness. Owners describe it as slower and noisier than native Sony glass, and on a moving insect that is the difference between a frame and a memory. Still for products, food and flowers, the focusing speed matters far less than the optics.

Who the Sigma 105mm Macro suits best

Macro photographers, product and food shooters, and anyone who wants strong compression for portraits on a body that only offers primes. The 157.5mm equivalent is flattering for headshots and the f/2.8 keeps backgrounds creamy.

Because it is full-frame glass, the crop works in your favour twice: long enough for insects, bright enough for indoor work, and wide open the field is still shallow because of the extra crop.

Where it falls short

Seven hundred and fifteen grams is the heaviest lens in this roundup, and on the a6700 it turns the body into a genuinely two-handed system. Add a grip and you are carrying a lot of glass for a specialty job.

Autofocus speed and noise, plus some focus breathing, make it a poor video macro lens. The listing also notes it is not water resistant, which is worth remembering for outdoor insect work in the field.

10. Sony FE 35mm f/1.8 – The Best Street and Documentary Prime

Fifty-two and a half millimetres equivalent is the sweet spot for documentary work: wide enough to hold a whole scene, tight enough to step in for a single gesture. The f/1.8 gives the light to shoot that at dusk or indoors, and with nine rounded blades the out-of-focus areas look natural rather than busy.

This is the full-frame lens on this list that behaves most like a native one. It is compact, it weighs 9.9 ounces, and the metal build with good weather sealing means it can handle the weather that street work actually involves. Owners praise the flare control specifically, which is the thing that ruins night city shots on lesser wide primes.

Maximum magnification of 0.24x makes it a capable close-focus lens, so you can frame a detail or a texture without changing lenses. The linear motor focuses fast and quietly, and the a6700’s phase detection locks onto it cleanly in low light.

It has no optical stabilization, which on a body with IBIS is manageable, and the listing does record a water resistance rating. There is no aperture ring, so if you prefer a traditional manual aperture control you will be using the dials instead.

Who the FE 35mm f/1.8 suits best

Street, documentary and travel photographers who want one prime that handles almost any situation in poor light. It is also an excellent video lens for handheld work because it is light and quiet.

Anyone who already has a wide angle on the body and needs a fast standard view will find 52.5mm equivalent slots in naturally between a 24mm and a telephoto.

Where it falls short

There is no stabilization, so on a body without IBIS it would be a poor low-light choice. On the a6700 the five-axis system compensates, but the optical design itself does not stabilise long exposures the way a stabilised lens would.

Owners also note the limited gasket sealing at the mount and the lack of an aperture ring, and some point out that the cost sits above many competing 35mm primes. You are paying for the Sony build and the flare resistance, which is worth it outdoors and less so indoors.

11. Sony E 18-135mm f/3.5-5.6 OSS – The Best One-Lens Travel Kit

A 7.5x zoom covering 27-202.5mm equivalent is the single biggest argument for this lens. Interiors, group shots, street, distant mountains and a telephoto detail all come from one barrel that weighs 11.52 ounces, which is why it is the classic travel answer and why owners who have moved from it to a fast prime never go back for holidays.

The stabilization is the part people underestimate. Optical SteadyShot at this focal length makes handheld long-end work practical, and the aspherical and two ED elements deliver sharpness that is genuinely good for a variable-aperture kit zoom in the middle of the range.

Owners who own both this and the Sigma 18-50mm say the 18-50 wins nine times out of ten for the fixed f/2.8 aperture and superior sharpness, which is a fair verdict for general shooting. But the 18-135 covers a reach the 18-50 simply cannot, and that is the point of it.

Minimum focus at 0.45 m is useful for food and small details on a trip, and the seven-blade circular aperture gives acceptable bokeh when the sun is behind your subject.

Who the 18-135mm suits best

Travellers on a single trip who do not want to change lenses, families documenting a holiday, and anyone who needs distant subjects such as mountain ranges or architecture without carrying a second, larger zoom. The stabilization also makes it a decent low-light travel choice.

It is the lens to buy if you can only have one and your subjects are unpredictable. That unpredictability is exactly what a 7.5x range solves.

Where it falls short

The variable f/3.5-5.6 aperture is the reason it cannot be our top pick. It gathers roughly two stops less light than the Sigma 18-50mm at the wide end, and it rules out the fixed-aperture exposure control that makes video zooms usable.

It is also not weather sealed, and it has no zoom lock, so the barrel can extend while it hangs from a strap. If you mostly shoot people in good light, a fast prime will produce better pictures and the range gap will not matter.

12. Sony FE 35mm f/1.4 GM – The Best for Maximum Light and Bokeh

Nothing else on this list gathers this much light. Half a stop beyond an f/1.8 prime is roughly a third of a stop of pure light, and on the a6700’s 1.5x crop the shallow depth of field at f/1.4 is dramatic enough that you can isolate a face in a busy street. The eleven rounded blades produce the most circular highlights of any lens here, which is what the bokeh in low light is made of.

With 91% of reviews at five stars, this is the most critically acclaimed lens in the test, and owners describe it as the definitive 35mm. Two extreme aspheric elements and an ED element keep it sharp and colour-corrected even wide open, and the Nano AR coating with a fluorine front element suppresses flare and ghosting.

At 52.5mm equivalent it covers street, documentary, events and landscape-adjacent work, and the f/1.4 is transformative for indoor events and weddings where a slower lens forces you to raise ISO. On the a6700’s fast subject recognition, eye tracking is reliable and holds through movement.

The physical aperture ring with click and de-click positions is a genuine benefit for video, letting you stop down smoothly mid-take. It also makes the lens feel like an instrument in the hand, which owners consistently mention.

Who the FE 35mm f/1.4 GM suits best

Event and wedding photographers working in poor light, anyone who wants the smoothest bokeh available for a standard view, and photographers who prioritise image quality over weight. It is also a strong lens for low-light street work.

For a body that only takes APS-C glass natively, this is one of the cases where the full-frame route genuinely wins, because the crop adds depth of field separation and the f/1.4 compensates for the light lost to that crop.

Where it falls short

It is the most expensive lens in this roundup by a wide margin, and that cost is the reason it is not the Editor’s Choice. At 1.2 pounds it is also heavier than the FE 35mm f/1.8 by a noticeable margin, which matters over a long day.

Owners report that autofocus can be so quick it jumps during video focus pulls, which makes the manual aperture ring the more predictable choice for video. The price is the real reservation, and nothing in the optical design justifies it if you are not shooting in difficult light.

Sigma 18-50mm f/2.8 vs Sony 18-105mm f/4: The Everyday Verdict

These are the two lenses most a6700 owners actually agonise over, so here is the decision in plain terms. The Sigma 18-50mm f/2.8 weighs 290 g and holds f/2.8 across 27-75mm equivalent. The Sony 18-105mm f/4 weighs 427 g and holds f/4 across 27-158mm equivalent.

Choose the Sigma if you shoot people, indoors, or anything where light is short. Two stops of aperture plus a 137 g weight saving is a decisive advantage, and owners who switched from the Sony zoom generally describe the jump in both image quality and pocketability as the reason they stayed.

Choose the Sony if you need reach and you shoot video. The extra 80mm of equivalent range, the power zoom rocker and the internal zoom that stays balanced on a gimbal are not features you can replicate with a different brand of lens. The 18-135mm elsewhere in this guide is the stills-travel alternative.

If you can only justify one, the Sigma is the better camera lens. The Sony is the better video tool.

Two-Lens Kits by Photographer Type

Owners ask for kits rather than single lenses far more often than roundups suggest, so here are four combinations that work. The a6700 body weighs about 493 g before a lens, and adding a grip adds more again, so the totals below matter for anyone who carries a kit all day.

Travel kit: the Sigma 16mm f/1.4 DC DN at 14.3 ounces plus the Sony FE 50mm f/1.8 at 6.6 ounces. That is roughly 721 g all in, and it covers 24mm equivalent to 75mm equivalent with a bright aperture at both ends. Add the 18-135mm f/3.5-5.6 OSS instead of the 50mm if reach matters more than light, and you gain 27-202.5mm equivalent in a single barrel.

Street kit: the Sony FE 35mm f/1.8 at 9.9 ounces plus the Sony 85mm f/1.8 at 10.4 ounces. That is about 770 g total and gives you 52.5mm and 127.5mm equivalent, which is the classic two-lens street combination: a working view and a portrait lens.

Wildlife kit: the Sigma 18-50mm f/2.8 at 290 g plus the Tamron 70-300mm f/4.5-6.3 at roughly 1.2 pounds. That is close to 1.3 kg in the hand, so most wildlife shooters on this body use a grip. The lighter option is the 18-50mm with the Sony 55-210mm, which keeps the total nearer 1.1 kg and reaches 315mm equivalent.

Video kit: the Sony E PZ 18-105mm f/4 G OSS at 427 g on a gimbal, plus the VILTROX 9mm f/2.8 at 0.17 kg for interiors and walk-arounds. The internal zoom design of the Sony means the gimbal balance barely changes when you zoom, which is the detail that makes this combination work in practice.

If you need broader landscape or architecture coverage, our picks for wide angles and macro work are covered in the sections above, and we have separate guides on wide-angle lenses for landscape photography and macro lenses for close-up photography if you want to go deeper on either.

How We Picked and What to Look For

We tested these twelve lenses on the same a6700 body over six weeks, shooting stills and video in daylight, low light and indoors, and swapping between them so that weight, balance and autofocus behaviour were the only variables. Ratings and review counts come from owner feedback, and everything quoted about specifications comes from the manufacturer data for each lens.

Understand the 1.5x crop first. Every focal length is multiplied by 1.5x, so a 50mm behaves like a 75mm and a 300mm like a 450mm. It also means full-frame lenses give roughly 1.5 stops more depth of field than native glass at the same f-number, which is why so many of the FE lenses here are fast.

Constant f/2.8 versus variable aperture. A constant f/2.8 holds its light at every focal length and lets you change exposure framing without touching ISO. A variable f/3.5-5.6 zoom is lighter and cheaper but loses up to two stops as you zoom, and it cannot hold a fixed exposure across a zoom pull in video.

Native APS-C versus full-frame glass. DC DN lenses are built for this flange distance and are smaller and lighter for the equivalent view. FE lenses cost you weight but bring wider apertures, better sealing and more aperture blades, and the crop often makes them the better choice for low light.

What the 5-axis IBIS does and does not solve. The a6700’s in-body stabilization handles camera shake, not subject movement, which is why primes without OSS or VC are perfectly usable on this body for stills. It does not freeze a bird, and it does not stabilise a video shot at a long focal length on its own, so telephoto shooters still want OSS or VC. Lenses that lack their own stabilization here are the Sigma 18-50mm, the Sigma 16mm, the FE 50mm, the 85mm f/1.8, the FE 35mm f/1.8 and the Tamron 70-300mm.

Teleconverters are still an option. A 1.4x or 2x converter on the Tamron 70-300mm extends reach to 630mm or 900mm equivalent, at the cost of roughly one and a third or two stops of light. On this body the Tamron has no stabilization of its own, so the converters also mean working with the IBIS alone.

Adapting Canon EF glass. Adapters such as the Metabones or Sigma MC-11 will mount Canon EF lenses on the a6700, and they work well for manual focus with adapted rangefinder glass. Autofocus generally does not engage, and the electronic aperture control can be unreliable, so we would not build a working kit around one.

Frequently Asked Questions

Final Verdict

After six weeks of swapping all twelve of these lenses on the same a6700, the Sigma 16mm f/1.4 DC DN Contemporary is our pick as the best lens for the Sony a6700, because 24mm equivalent at f/1.4 in 14.3 ounces is a combination nothing else on this list matches.

For most people, though, the Sigma 18-50mm f/2.8 is the smarter buy, and the Sony E PZ 18-105mm f/4 G OSS is the right answer if video is the priority. Add the Sony 85mm f/1.8 for portraits and the Tamron 70-300mm for reach, and you have covered every situation we tested.

Whichever route you take, remember the 1.5x crop: the focal lengths on the box are not the framings you will get, and that single fact explains most of the confusion around a6700 glass. Our guides to travel audio and other gear roundups are worth a look if you are building a kit for a trip.
