The Sony E 15mm F1.4 G ($749.99) is a much-anticipated wide prime lens for the company's APS-C mirrorless camera system. It straddles the line between a wide and standard angle, with a fixed view that's just a smidgen wider than what you get from the E PZ 16-50mm starter zoom. It competes directly with the affordable Sigma 16mm F1.4 DC DN Contemporary, which is often available for less than its $450 list price. The Sony E 15mm is a bit slimmer than the Sigma, but just as sharp. The lens also notably adds robust weather protection and includes an aperture control ring. We continue to recommend the Sigma if you're on a budget, but if you've got the means, the E 15mm F1.4 G is a worthwhile investment and an Editors' Choice winner.

G Series Prime

The E 15mm F1.4 G is the first prime lens of its type for APS-C cameras and joins zooms like the E 16-55mm F2.8 G in Sony's lineup. G lenses include some features you don't get on basic entries for the system; for example, dust and splash protection as well as more thoughtful tactile controls. The family sits beneath the company's highest class of lenses, G Master, but, so far, Sony has released those lenses only for full-frame cameras. You can use lenses like the FE 14mm F1.8 GM with an APS-C body if you want, but you end up spending and carrying more than you need.

The 15mm F1.4 G is relatively easy to carry, on the other hand. It measures 3.0 by 2.5 inches and weighs just 7.7 ounces. It's much more manageable than the Sigma 16mm F1.4 (3.6 by 2.8 inches, 14.3 ounces). It's not the lightest wide lens for the system, however. Sony also sells an ultra-light E 16mm F2.8 prime (0.9 by 2.4 inches, 2.4 ounces) for around $250, but it's an old lens from 2010 and doesn't work well on new cameras. No one should buy it and Sony should stop selling it.

The lens uses a sturdy polycarbonate construction material, just like the Sigma. This build choice is in line with recent G and GM series lenses. Sony has largely abandoned metal barrel optics because modern plastics are just as durable and provide cost- and weight-saving benefits. You can still find some metal lenses in the Sony lineup, but they're older designs like the Zeiss Sonnar T* E 24mm F1.8 ZA.

For years, we criticized Sony for including weather protection in midrange APS-C cameras like the a6400, but not offering any protected lenses to match. The E 15mm F1.4 G (and other recent APS-C releases) is an exception that can resist dust and splashes. We're disappointed that the front glass omits anti-smudge fluorine, however, so you should use the included hood or add a 55mm filter to protect the glass from stray fingerprints.

Now our criticism is more in the lack of availability of quality cameras to match with a lens like the E 15mm F1.4 G. All of Sony's current-generation APS-C sensor models, the a6100, a6400, a6600, and ZV-E10 our out of stock, and a bit out of date versus more recently-refreshed cameras from other systems. The a6400 just came back into production, and still leads many competitors in autofocus performance, but isn't quite as stunning if you're critical about video. We hope to see Sony freshen its camera line to better match up with G series lenses.

Handling and Controls

The E 15mm F1.4 has more tactile controls than other E lenses. Sony typically reserves the aperture control ring for full-frame lenses but, here, it's just as functional. It moves from f/1.4 through f/16 in third-stop increments, as well as swaps to silent, click-free operation via a toggle switch. The barrel also includes a customizable button on its left side that you can configure via the camera menu.

Linear motors drive autofocus. Focus is quiet and practically instant—there's no delay when you shift focus from close to far-off targets. Manual focus response is linear as well, so it's based on how far (not how quickly) you turn the focus ring. That's good news for videographers who want to repeat focus racks. The lens also shows absolutely no focus breathing, another plus for video creators. A long throw, about 170 degrees to move from near to distant focus, is a benefit for precise adjustments, too.

Focus is available to 6.7 inches (17cm), which means you can get up close to subjects. The wide standard view means the macro capability isn't great, however; the lens manages about 1:6.7 life-size reproduction at best.

There's no optical stabilization, but we don't expect to see that feature in a wide F1.4 prime. From a practical standpoint, most photographers can likely manage motion-freezing handheld speeds without a problem, though you should pair the lens with a stabilized sensor camera (either the a6500 or the a6600) if you like to make long exposures without a tripod.

For video, the lack of optical stabilization is a bit more of an issue. For the best results, you should use a tripod or gimbal for stabilization. The ZV-E10, a camera made for vloggers and content creators, offers Active Shot digital stabilization, but it limits the view of the lens by a 1.44x factor. If you expect to rely on Active Shot for handheld footage and want a wide look, either the E 11mm F1.8 prime or E PZ 10-20mm F4 G are more sensible choices because of that additional crop.

E 15mm F1.4 G: In the Lab

I paired the E 15mm F1.4 G with the 24MP ZV-E10 and Imatest software to check its resolution. It captures excellent resolution at wide apertures (2,800 lines) and crosses over into outstanding territory by f/4 (3,200 lines). There's some flexibility here: wide apertures offer a shallow depth of field and capture plenty of light in dim conditions, or you can stop down a little bit for tack sharp results from center to edge.

The aperture goes all the way down to f/16, but image quality suffers at the smallest setting. You are also more likely to see some ghosting, bright spots of light caused by internal reflections, at f/16. Even so, you should stop the lens down to get landscapes with the sunstar effect—the E 15mm has a seven-blade aperture that draws crisp 14-point sunstars. At wider apertures, lens flare is much less of an issue, though you might still see soft, glowing flare when you point the lens at a strong light source.

Sony leans on in-camera corrections here to remove barrel distortion and vignetting, both of which are visible in Raw images. Camera JPGs and videos show straight lines, though some corner dimness is present at f/1.4. If you opt for Raw capture, you need to apply distortion correction manually or wait for a correction profile. Adobe Lightroom Classic includes one-click corrections for most major lenses and it's only a matter of time before the photo editing software adds one for the E 15mm F1.4 G.

The lens controls chromatic aberration very well. I made several images of power lines against a clear sky at f/1.4 and couldn't spot any false purple color around them, even toward the corners. I noticed some longitudinal chromatic aberration (LoCa) in transitions between in- and out-of-focus areas, but you have to pixel-peep to see that flaw in many instances.

One of the reasons to opt for an F1.4 lens is to snap photos with soft, defocused backgrounds. The character of the defocus, referred to as bokeh, is lovely here. Backgrounds fall off into blur, with soft-edge highlights that make for less busy backgrounds than the wider-angle E 11mm F1.8. Highlights are mostly round at wide apertures but show a cat's-eye shape toward the corners of the frame. Use a moderate aperture, from around f/2 to f/5.6, at close distances to get rounder highlights at the periphery.

A Worthwhile Splurge for Sony APS-C Creators

The E 15mm F1.4 G fills a gap in Sony's E-mount lens series, and is a strong debut as the first made-for-APS-C F1.4 from the company. Image quality is right up there with the company's best E-mount lenses, and we're quite happy with the design: weather protection, linear focus motors, and tactile controls justify the price.

There are alternatives to consider, of course. You shouldn't buy the cheap Sony E 16mm F2.8, because it doesn't work well with new cameras; the Sigma 16mm F1.4 DC DN Contemporary is a better pick if you're shopping on a budget. The Sigma retails for $450 but is often on sale (you can get it for around $375 as of this writing). It's an excellent performer optically, but doesn't focus with the same aggression as the Sony, isn't fully weather-sealed, and weighs twice as much. Still, we like it enough recommend as an affordable alternative.

The E 15mm F1.4 G is a worthwhile upgrade if you've got the means. At around $750, it's one of the more expensive primes you can get for an a6000 series camera, undercutting the costliest, the long-running Zeiss 24mm F1.8, by just $50. The E 15mm's focal length is a better fit if you favor broader views, and bringing more modern optics and weather resistance along for the ride. We'd love to see Sony follow with a new generation of cameras to really make the lens sing, but that doesn't stop us from naming the 15mm F1.4 G an Editors' Choice for creators already entrenched in Sony's system.
