The Sony ZV-E10 has become a popular choice for vloggers who live and die by their YouTube views. But its well-established lens system lacks any ultra-wide prime lenses, which are useful tools for recording video at arm's length. The E 11mm F1.8 ($549.99) addresses this shortcoming, and is the widest autofocusing prime you can get for crop-sensor E-mount mirrorless cameras. If you like the view at wide angles and favor the defocused backgrounds an F1.8 lens delivers, the E 11mm is worth a look. Just note that it isn't as well-corrected optically as the next-widest first-party prime for the system, the E 15mm F1.4 G.

Wide Angle and Aperture

The E 11mm F1.8 realizes a much wider view than the E PZ 16-50mm F3.5-5.6 OSS or E 18-135mm F3.5-5.6 OSS zooms that Sony bundles with its APS-C mirrorless cameras. This new lens squeezes more of the world into the frame, a benefit for photographers who explore urban environments, capture landscapes, or work in tight interiors.

Sony already has some wide-angle options in its library, but the E PZ 10-20mm F4 G and E 10-18mm F4 OSS zooms don't gather nearly as much light as this F1.8 prime. You won't be able to adjust the angle of view with the E 11mm, but its f-stop means you can easily blur backgrounds. Vloggers who often present to a camera can also likely find a reason to use this type of lens for walk-and-talk selfie footage as well as in the studio.

Although the E 11mm F1.8 is the widest autofocusing prime available for the system, its view is only slightly broader than the $400 Rokinon/Samyang 12mm F2.0 Sony AF or the pricey Zeiss Touit 2.8/12 ($1,250). If you don't mind manual focus, you can get a wider view with lenses with a shorter focal length, like the Venus Optics 9mm Zero-D.

Despite netting big views, the E 11mm F1.8 is an easy lens to carry. It measures about 2.5 by 2.5 inches (HD), weighs just 6.3 ounces, and supports 55mm front filters. The box includes a petal-style hood along with front and rear caps.

The front element skips anti-smudge fluorine, so you may want to add a protective filter. The lens resists dust and splashes, but most of Sony's APS-C series cameras omit weather protection. The most recent models to offer this feature are the a6400 and a6600. Both have been out of production and out of stock at retail for months, but Sony just restarted manufacturing for the a6400.

Snappy Linear Autofocus

The E 11mm F1.8 doesn't offer much in the way of manual controls, but it covers the basics: there's an AF/MF toggle, a customizable function button, and the manual focus control ring. If you're looking for a more tactile experience with on-barrel aperture control (something you don't get on the 11mm), a G series option such as the E 15mm F1.4 G is a better fit.

Autofocus response is lightning-fast; the lens shifts focus from close to distant subjects in an instant with the ZV-E10 in testing. Manual focus is an option too. The focus response is linear, so you can easily repeat focus racks. The focus throw is fairly long: It takes about 170 degrees of rotation to move across the entire range, which is good news for anyone who wants to make precise changes to the plane of focus.

The 11mm focuses close, up to about 5.9 inches, which is good enough for 1:5 macro images. You shouldn't turn to this lens for traditional insect or flower macros, but it's a very good choice if you want to play with perspective and show a wide background behind a nearby subject.

Focus breathing, an unwanted effect in which the angle of view changes as you adjust focus, is nearly absent here. That means the frame stays steady when you present to a camera and that you can make creative rack focus video shots to your heart's content without anything distracting from your subjects.

The lens doesn't feature optical stabilization, though we don't consider that to be a surprise or glaring omission—it's just not something you see in this type of lens. Photographers aren't likely to miss the feature, though it does mean you likely need to bring a tripod or find a place to stabilize your camera if you want to make long exposure photos. Alternatively, you can pair the lens with an a6500 or a6600 camera as both models have a stabilized sensor.

Many vloggers who use the ZV-E10 may still look to the 11mm F1.8 for handheld video, however. The ZV-E10 doesn't offer physical stabilization but has an Active SteadyShot digital option. This mode crops the angle of view (at 1.44x) but is effective at reducing shake and jitter in video. If you want to realize the full view of the lens and get smooth handheld video from the ZV-E10, you need to add a gimbal to your kit.

E 11mm F1.8: In the Lab

I paired the E 11mm F1.8 with the 24MP ZV-E10 and Imatest software to check its resolution. Even wide-open, it shows excellent detail across the frame (2,800 lines). Edges suffer, however, and there's some loss of light and contrast as you look away from the center of images.

The lens does a better job at the periphery by f/2.8 and delivers its sharpest results (an outstanding 3,100 lines) from f/4 through f/8. We see some loss of clarity at f/11 and f/16, but you should set the lens to its narrowest f-stop to get the best possible 14-point sunstars. The starburst effect is pronounced, but not as clearly defined as in results from the E 15mm F1.4 G. The sunstars are somewhere between mushy and crisp, with sharp tines that separate into streaks as they move away from the center.

You're sure to see some flare and ghosts in these types of shots; they're hard to avoid at f/16. The prominent green ghosts the lens shows are heptagonal as a result of the 11mm's seven-blade aperture. Generally speaking, expect some ghosts when you work against a strong, prominent backlight, such as the sun.

The E 11mm relies on correction profiles to compensate for distortion and an optical vignette when you take JPG images or record video. If you work in the Raw format, you need to contend with both, as the barrel distortion is quite noticeable and corners are dim at f/1.8 and f/2. We're reviewing the lens ahead of its announcement, but expect Adobe to add a Lightroom correction profile soon.

Defocused backgrounds are achievable because of the f/1.8 aperture and I'd describe the 11mm's bokeh quality as characterful. Hard-edged highlights give backgrounds a busy, soap bubble look. Highlights are generally round when you shoot at the maximum aperture, though they take on a cat's-eye look toward the edges. And, at moderate apertures, the bokeh takes on a heptagonal shape. You can find some false purple and green color (also known as longitudinal chromatic aberration, or LoCa) in backgrounds if you look for it, but it's as much of a contributor to the lens character as the hard edges of the bokeh.

I note some lateral chromatic aberration (purple color fringing) in high-contrast areas of the frame, such as with tree branches and power lines against clear skies. The effect is visible from f/1.8 through f/2.8 and is more noticeable in camera JPGs than in Raw files I processed in Lightroom Classic. Sony embeds a CA correction profile in Raw files that does a better job than the ZV-E10's JPG engine.

A Wide Prime With Character

Sony has spoiled us a bit with lenses, and many of its recent entries are optical marvels with few critical flaws. The E 11mm F1.8 is proof that not every lens can be perfect, but it's by no means a dud. We're very happy with its resolution, for instance: It manages crisp detail on an APS-C camera like the ZV-E10, with outstanding results at the stopped-down apertures you're most likely to use for landscapes and similar scenes.

Flare should be a concern for landscape specialists, however. The lens tends to show some ghosting when you point it toward the sun. Both drone pilots who are considering the 11mm F1.8 as a lightweight prime for use with the Airpeak S1 and travel vloggers should consider this downside, too. Defocused backgrounds can also show a bit of a soap bubble effect. Whether this is a problem depends on your taste and how you use the lens.

All that said, we can still recommend the E 11mm F1.8. It's a well-made lens with weather protection and a speedy autofocus motor. It's also a much better value than the ancient Zeiss Touit 2.8/12, which I recommend against buying today. If you want a similar optic for less, you could consider the Rokinon 12mm F2.0 AF for $350, though we haven't yet tested it.
