The best Sony wide-angle lenses enable you to fit a sweeping vista into a single frame. Wide-angle lenses are among my personal favorites – all but essential for landscapes and cityscapes, helpful for architectural interiors, and great for emphasizing perspective to creative effect.
These are the best ones I’ve tested for the Sony E-mount ecosystem. All of these are lenses I’ve taken out into the field and tested in the lab to assess their resolving power, focusing capabilities, and ease of use. I’ve included zooms and primes, and options for both full-frame cameras (the A1, A7, and A9 ranges) and for APS-C Sony models (the A6000 and ZV-E ranges).
Let’s take a closer look at the best Sony wide-angle lenses for a range of different needs, budgets, and camera types. For more options in different focal lengths, see my general guide to the best Sony lenses, which includes standard and telephoto lenses as well as wide-angle glass.
Matthew Richards is a photographer and journalist who has spent years using and reviewing all manner of photo gear. He is Digital Camera World's principal lens reviewer – and has tested more primes and zooms than most people have had hot dinners – and that includes practically every Sony E-mount lense launched to date.

Best wide-angle zoom for pros
I loved the wow-factor that this lens delivers as soon as I put my eye to the viewfinder. Most ‘trinity’ f/2.8 wide-angle zooms serve up a 14-24mm zoom range, but this one goes even wider. An additional 2mm in focal length might not sound like a lot, but the more expansive field of view is immediately obvious through the viewfinder. When this lens was launched, Sony already had a smaller FE 12-24mm F4 lens on the market, but I like the faster aperture of the newer model for freezing movement under dull lighting. It also gives more potential for blurring the background in close-up shots, especially towards the longer end of the zoom range. Bokeh is soft and dreamy, typical of G Master lenses.
I’m impressed that the lens is packed full of top-quality glass, including three XA (eXtreme Aspherical) elements that are manufactured to a tolerance of just one hundredth of a micron. The payoff is superb sharpness for an ultra-wide-angle lens that extends right out to the edges and corners of the image frame. I also find that autofocus is very fast for a lens with such wide-diameter elements. That’s thanks to four high-speed XD (eXtreme Dynamic) Linear Motors, two for each of the pair of groups that move during focusing.
As with many ultra-wide-angle lenses, this one has an integral hood. As such, there’s no filter attachment thread, but at least there’s a slot in the mounting plate for inserting gel filters.

Features ★★★★★ |
The lens features no less than three XA (eXtreme Aspherical) elements) and other specialist glass, plus a new Nano AR Coating II. |
Design ★★★★★ |
Pro-grade build quality is the order of the day but the lens isn’t overly heavy. The hood is typically integral but there’s a gel filter holder at the rear. |
Performance ★★★★★ |
Autofocus is super-fast, image quality is impeccable with superb sharpness and resistance to ghosting and flare. |
Value ★★★★☆ |
It’s much pricier than the competing 14-24mm f/2.8 Sigma lens but goes even wider for viewing perspective. |
Best affordable pro wide-angle zoom
I was a big fan of Sigma’s 14-24mm F2.8 lens for DSLRs, and this E-mount version is even better. It’s redesigned from the ground up to make the most of Sony mirrorless cameras. Optical highlights include three aspherical elements, including a high-precision, large-diameter one at the front, an FLD (‘Fluorite’ Low Dispersion) element, and no less than five SLD (Special Low Dispersion) elements. A significant addition is the use of NPC (Nano Porous Coating) as well as Sigma’s more conventional Multi-Layer Coating.
In practical terms, I’ve found that the lens delivers superb sharpness and clarity, even when shooting wide-open at f/2.8, throughout the zoom range. Color fringing is entirely negligible, and there’s excellent resistance to ghosting and flare. Barrel distortion can be noticeable in the shorter half of the zoom range, but there’s less reliance on automatic in-camera correction than with many recent lenses designed for mirrorless cameras.
Like most other recent Sigma Art and Sports lenses, this one has really solid build quality and is extensively weather-sealed. I like that the AF-L (Autofocus Lock) button is featured and that I can customize it for other uses via in-camera menus. All in all, this Sigma looks, feels, and performs like a fully pro-grade ‘trinity’ zoom, but for about half the usual price. Bargain!

Best affordable full-frame wide-angle zoom
I think this Tamron lens has a lot going for it. There’s no shortage of similar own-brand lenses, including the Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS, which is ‘slower’ but features Optical SteadyShot, and the Sony FE 16-35mm f/2.8 G Master II. A ‘trinity’ f/2.8 lens with a difference: the Tamron has a slightly more restrictive zoom range and marginally less maximum field of view, but it’s relatively compact and lightweight, and it sells for a much more affordable price. That ticks a lot of boxes on my wish list.
Although small and light, I like that the Tamron feels solid and well-built, and includes weather seals. I also like its nippy RXD (Rapid eXtra silent stepping Drive) autofocus system, which I’ve found to be fast, virtually silent, and consistently accurate. What matters most to me is image quality, and the Tamron scored highly again in this respect. Corner-to-corner sharpness is excellent, and there’s virtually no color fringing. Unusually for a wide-angle lens, there’s a little pincushion distortion in the longer half of the zoom range, but automatic in-camera correction is available.
Especially for landscape photography, I feel that the inclusion of a front filter thread is a bonus. It means I can use the likes of neutral density and ND grad filters easily, and the 67mm thread is refreshingly modest for a wide-angle lens.

Design ★★★★★ |
The lens is solidly built yet amazingly compact and lightweight for a wide-angle ‘trinity’ zoom. |
Performance ★★★★★ |
All aspects of image quality are highly impressive, throughout the entire zoom range. |
Value ★★★★★ |
The Tamron is standout value for a wide-angle zoom with a constant f/2.8 aperture. |
Best APS-C wide-angle zoom
Sony’s APS-C format cameras tend to be small and lightweight, and I like that this E-mount lens follows suit. Weighing in at just 335g, it feels beautifully balanced on slimline Sony bodies, and I like that the 11-20mm zoom range delivers good wide-angle coverage, equivalent to 16.5-30mm in full-frame terms. Another bonus for me is the relatively fast and constant f/2.8 aperture, which I find extends the versatility of the lens.
I feel that the build quality and handling are very good. The Tamron features weather seals and comes with a bayonet-fit petal-shaped hood. I find it useful that, unlike with many wide-angle lenses, I can easily attach filters via the 67mm attachment thread. Autofocus is fast and virtually silent, as I’d expect from a stepping motor-based system. However, there’s no optical image stabilizer, which can be a concern, as so many APS-C-format Sony mirrorless cameras don’t have in-body stabilization.
Another thing I like about this lens is its short minimum focus distance of just 0.25m at the wide-angle end of the zoom range, although it stretches to 0.24m at the long end. Either way, I can get in really close to subjects and exaggerate perspective at wide-angle zoom settings. As with many wide-angle lenses, lab test results don’t flatter the Tamron, but in real-world shooting conditions, I found sharpness very impressive across the whole image frame, right into the corners. There’s some reliance on automatic in-camera distortion correction, but unlike many recent wide-angle lenses for mirrorless cameras, it’s not wholly dependent on it.

As an ultra-wide-angle zoom lens with a fast and constant f/2.8 aperture rating, it’s great value for money. |
Best professional wide-angle prime lens
I love that this Sony lens is so compact and lightweight for an ultra-wide-angle, full-frame-compatible lens with such a fast f/1.8 aperture rating. Even so, there’s a lot packed in when it comes to handling exotica and all-around performance. I’ve found that the electronically-coupled manual focus ring has a smooth and precise action with a linear response that’s well suited to both stills and video shooting. A further bonus for video is that the manual aperture ring can be de-clicked via a switch on the right-hand side of the barrel. On the left, there’s an AF-MF focus mode switch and a function button, which is nominally for AF Hold, but you can customize its action via in-camera menus.
Build quality feels very solid for such a lightweight lens, and extensive weather seals are fitted to all the joints, mounting plate, switches, and buttons. Fluorine coatings are applied to the front and rear elements. Although small, the lens packs 14 optical elements. Specialist glass includes two ED (Extra-low Dispersion) elements, one Super ED element, and two high-precision XA (eXtreme Aspherical) elements, plus a regular aspherical element. The mix intends to maximize sharpness, contrast, and clarity while keeping aberrations to a minimum. Nano AR Coating II is also applied to minimize ghosting and flare.
I found that sharpness is superb, right out to the extreme corners of the frame, even when shooting wide-open at f/1.8. There’s also remarkably little coma and astigmatism. That’s great news for astrophotography and shooting nighttime cityscapes, as it ensures that stars and pinprick lights don’t take on irregular shapes towards the edges and corners of the frame, especially when shooting at the widest aperture.

Best affordable full-frame wide-angle prime
The Sigma 20mm f/2 DG DN | C joins a growing range of fairly fast primes for Sony E-mount cameras in Sigma’s ‘I-series’ range. I like that the look and feel of the lenses is so consistent across the range, which includes 24mm, 35mm, and 65mm f/2 DG DN | C options, as well as a slower 45mm f/2.8 lens. For me, the ‘Contemporary’ design ethos works well, delivering excellent performance in a compact and lightweight build.
I’m impressed that there’s some impressive glass shoehorned into the diminutive construction, with 13 elements in total, include three high-precision glass-molded aspherical elements, one SLD (Special Low Dispersion) element, and one top-spec FLD (‘Fluorite’ Low Dispersion) element. Sigma’s conventional Super Multi-Layer Coating and more high-tech Nano Porous Coating are both employed to fend off ghosting and flare.
As with other lenses in Sigma’s I-series Contemporary lineup, I like the build quality, which is based on a coated brass mounting plate, a metal barrel, and even a metal lens hood and lens cap, the latter of which is magnetic. A more regular plastic lens cap is also supplied in the box. The construction features multiple weather-seals and is dust- and moisture-resistant. Handling is enhanced by an aperture control ring which operates in one-third f/stop increments, but there’s no ‘de-click’ option. Sharpness is very good, but automatic in-camera correction comes in useful to reduce distortion and wide-aperture vignetting.

Best full-frame pancake prime lens
At less than an inch thick and tipping the scales at a mere 6oz, this Viltrox lens ticks all the right boxes for a ‘pancake prime’. I also have an older Viltrox AF 28mm f/4.5 pancake lens in my collection but the relatively new 26mm is much more sophisticated, adding manual focus instead of being limited to autofocus, and having a fully adjustable aperture diaphragm instead of a fixed f/4.5 aperture.
On full-frame cameras, I like that this lens has a generously wide-angle 26mm focal length, but that's not the whole story. I love that that I can also use it in crop mode, or on an APS-C format camera body, where it gives an entirely natural perspective, equating to an ‘effective’ 39mm focal length.
Either way, the actual or effective focal length is coupled with a fairly fast f/2.8 aperture that enables quick shutter speeds for freezing motion, even under dull lighting conditions. That adjustable diaphragm that I mentioned also comes with a physical aperture control ring, which is a neat handling extra.
Best of all, the little Viltrox delvers excellent sharpness and clarity, punching well above its weight in terms of performance.

Best APS-C wide-angle prime
A small lens with a big heart and a big viewing angle, I love how this Sony 11mm shoehorns so much into the image frame. I find it ideal for everything from cramped architectural interiors to sweeping landscape vistas and cityscapes, while its fast f/1.8 aperture makes it equally adept for astrophotography. Buy one, and it won’t be long before you wonder how you ever managed without it.
I really like that the lens is designed to be equally adept at shooting stills and movies, boasting two linear stepping motors that deliver super-fast autofocus for stills and smooth, virtually silent focus transitions for movies. The minimum focus distance of 0.15m shrinks to just 0.12m in manual focus mode, delivering a tight depth of field at f/1.8 for close-ups or using the lens for vlogging. Handling benefits from an AF/MF switch and a customizable autofocus-hold button.
I also like that the lens is neatly compact and lightweight, ideally suited to slimline Sony A6000-series camera bodies. Even so, it packs quality glass, including three aspherical elements and three ED (Extra-low Dispersion) elements to optimize image quality, while build quality is convincingly robust, featuring multiple weather seals.

Best value APS-C prime
When I think of ultra-wide-angle lenses with a relatively fast f/2.8 aperture, two things spring to mind – size and weight. They tend to be big and heavy, which is the last thing I want if I’m trekking off across tricky terrain, in search of great landscape photo opportunities. The same thing goes for pounding city streets, looking for great architectural shots. This lens fits the bill perfectly, and really redresses the balance, so to speak. It’s so small and light for an ultra-wide-angle lens that it almost seems to defy the laws of physics. Indeed, it weighs in at a mere 175g or 6.2oz.
Typical of Viltrox's ‘Air’ series lenses, it has a very streamlined build that doesn’t include an AF/MF focus mode switch, nor an aperture control ring. The upside is that it really couldn’t be any simpler to use and feels like a perfect fit for Sony’s slimline APS-C format mirrorless cameras. I also like that it has a separate rather than integral hood, enabling the easy fitment of landscape-friendly filters.
It’s only natural to think that if a lens is this small, there’s going to be a compromise in terms of image quality and all-around performance. I was pleasantly surprised that the Viltrox autofocuses with speed and consistent accuracy, and that in real-world shooting, it maintains impressive levels of sharpness right out to the edges and corners of the image frame. Even the asking price is super-small, making it standout value for money.

Design ★★★★☆ |
The emphasis is on convenience and simplicity, so the lens is compact and lightweight but lacks an AF/MF switch or an aperture control ring. |
Performance ★★★★☆ |
Image quality is very pleasing, with impressive sharpness right out to the edges and corners of the image frame. |
Value ★★★★★ |
For an ultra-wide-angle prime lens with a fairly fast f/2.8 aperture rating, it’s incredible value for money. |
Best wide-angle lens for video
The first thing that hit me about this wide-angle zoom lens for Sony’s APS-C format mirrorless cameras is just how small it is. To me, it feels much more like the size and weight of an ultra-compact standard kit zoom lens with a variable (and slow) aperture rating. The fact that Sony has managed to shoehorn such an expansive range of viewing angles with a constant f/4 aperture into such a small lens, complete with motorized zoom, really is quite something. Especially as image quality and overall performance are so excellent.
I find that the silent power zoom facility makes the lens ideal for vlogging and general video shooting, but it’s equally adept at capturing stills of anything and everything from architectural interiors to sweeping landscapes, or just for exaggerating perspective effects. The electronically coupled zoom ring feels wonderfully responsive, seamlessly converting the speed and amount of rotation to the resulting focal length. I also like the additional zoom lever that enables constant-speed adjustments right down to super-slow movements, ideal for avoiding jerky zoom transitions when shooting movies. I’m also pleased that there’s an optional grip and remote controller, plus a free app for controlling everything from my mobile phone.
Although really small, the lens feels very solid and well-built, and includes multiple weather seals around all the joints, buttons, and switches. Handling refinements include an AF/MF focus mode switch and a customizable focus hold button. I’m a bit disappointed that the lens lacks an aperture control ring, for which a de-clicked option would have been nice when shooting movies, but there’s only so much you can squeeze into such a small lens.

How we test lenses and lab test comparisons
The lens experts in our testing lab run a range of tests under controlled conditions. We take photos of Imatest SFR (spatial frequency response) charts, then use the Imatest Master testing suite to analyze sharpness, distortion, and chromatic aberrations at the centre of the image frame, corners, and mid-point distances across the range of aperture settings (up to f/22).
The graphs below show the comparative performance of the lenses in this guide, based on our in-house lab tests. For zoom lenses, we repeat our test at the widest and longest ends of the zoom range, plus intermediate 'mid-wide' and 'mid-telephoto' settings. Use the dropdown menus to select between them (for primes, the same data appears on all graphs for ease of comparison). Only full f-stops are labelled on the X-axis for sharpness, so, for example, an f/1.2 or f/6.3 lens would correlate to f/1 and f/5.6, respectively.
The Sony FE 14mm and Sigma 20mm prime lenses are pick of the crop for sharpness, although the Sony FE 12-24mm is highly impressive for a zoom lens and the Viltrox AF 26mm punches above its weight for a pancake lens. The Viltrox pancake is technically worst for color fringing but it's still of a very low order and well within the remit of automatic in-camera correction. The Sony E 11mm and E PZ 10-20mm APS-C format lenses rely entirely on automatic in-camera correction for distortion, more so than any of the other lenses in the group.
For more detailed graphs of each lens's performance, which give the full picture, check out the graphs in our full standalone lens reviews.

There's more to it than just the technical side, though! Beyond the lab, our reviewers test lenses in real-world environments. We work with lenses both indoors and outdoors, in studio conditions and in natural light, with as many different subjects as possible (or appropriate – there's no point testing a landscape lens' ability to shoot a portrait!).
We take into account everything from handling and ease of use to autofocus speed and the overall quality of the images produced.

How to choose
Prime or zoom?
Sometimes it’s hard to decide whether a zoom lens or a prime lens will be a better buy. Zoom lenses tend to be more versatile, as they cover a broad spread of focal lengths. However, there’s a lot to be said for prime lenses, which generally have a wider or ‘faster’ aperture rating and are often relatively small and lightweight. Some photographers find that they only tend to use wide-angle zooms at or near their shortest focal length anyway, which is another reason for considering a prime lens.
Do I need speed?
If you’re mainly using a wide-angle lens for landscape photography, you won’t need one with a really fast aperture rating, and an f/5.6 lens should suffice. That said, most of the lenses in this buying guide have aperture ratings of f/2.8 or faster. That’s a real bonus for astrophotography, for which wide-angle lenses are particularly well suited, as well as for shooting architectural interiors under low indoor lighting, and for night-time cityscapes.
How do I tell if a lens is full-frame compatible?
It can be tricky for the uninitiated to recognize the difference between Sony lenses that are made for full-frame or APS-C format cameras. The clue is in the title. APS-C format lenses have an ‘E’ prefix, whereas full-frame compatible lenses have an ‘FE’ prefix. Sigma designates its lenses as ‘DC’ for crop-sensor cameras and ‘DG’ for full-frame. Bear in mind though, that you can shoot with E lenses on full-frame cameras in crop mode, and with FE lenses on APS-C cameras with no limitations.
What’s the APS-C crop factor?
Sony’s APS-C cameras have an image sensor that’s the same size as a frame of ‘Advanced Photographic System type C’ film. That’s quite a bit smaller than a frame of 35m film, on which full-frame digital cameras are based. The outcome is that the ‘crop factor’ gives a 1.5x magnification in the focal length of lenses. For example, a 10mm wide-angle lens will give the same field of view as using a 15mm lens on a full-frame camera.
Do I need OSS?
Optical SteadyShot can be really useful if your Sony camera doesn’t feature IBIS (In-Body Image Stabilization). It’ll help counteract the effects of camera-shake and ensure you get sharp handheld shots more consistently with slow shutter speeds. However, OSS is generally not featured on wide-angle lenses, as camera-shake is less of a problem in handheld shooting compared with standard and telephoto lenses.
