Fujifilm's X lens system is home to tons of small, fixed-focal-length lenses, but the Fujinon XF 8mm F3.5 R WR ($799.95) is the first prime that matches up with its widest zooms. The travel-friendly lens offers an immersive angle of view, focuses quickly, and is fully weather-sealed for your outdoor adventures. It's a compelling option for both landscape photogs who want to pack light and vloggers who record at arm's length, but you should still consider spending a bit more for the XF 10-24mm F4 R OIS WR if you're willing to give up a bit of wide-angle coverage for greater versatility.

Incredibly Wide Views From a Lightweight Package

The XF 8mm F3.5 R WR is small compared with competing options of a similar focal length and APS-C primes in general. It measures just 2.3 by 2.6 inches (HD), weighs 7.6 ounces, and supports 62mm creative filters. It's a breath of fresh air for photographers who want ultra-wide views without dealing with the bulk (4.8 by 3.5 inches, 1.8 pounds) or the price of the XF 8-16mm F2.8 R WR ($1,999.95).

Fuji also sells the XF 10-24mm F4 R OIS WR ($999.95), which doesn't go quite as wide but has stabilized optics. If you're willing to forgo autofocus, you can also check out the Venus Laowa 9mm F2.8 Zero-D.

The XF 8mm isn't just unique within Fuji's ecosystem. Neither Canon nor Nikon offers anything comparable, and the closest Sony gets is its E 11mm F1.8 G. Of course, 8mm is considerably wider than 11mm; it matches the views of a rectilinear 12mm full-frame lens. This perspective isn't ideal for everyday subjects but can be invaluable for capturing architecture, cityscapes, and broad landscapes in their entirety or showing your surroundings as you vlog.

The lens feels premium thanks to its metal barrel and full weather protection. I didn't take it out in rough weather because I was testing it with a camera that omits weather protection, but, in my experience, Fuji's weather sealing is among the best around. Another nice design touch is that the front element features an anti-smudge fluorine coating. The lens ships with a hood, as well as front and rear caps.

Handling and Focus

As I mentioned, the XF 8mm doesn't weigh much, so it pairs well with smaller Fuji cameras and the larger X-H2 series bodies equally well. I tried it with the mid-sized X-S20, which made for an enjoyable, lightweight kit.

The lens itself has a couple of notable control surfaces. The manual focus ring has a knurled metal finish and turns with a pleasing amount of resistance. I expect most photographers to rely on its autofocus—which is quick, quiet, and accurate—but manual operations work just fine. The dampened ring helps make fine adjustments possible, though the lens has a very short focus throw like most others in this focal range.

Almost all Fuji lenses include on-barrel aperture control. The XF 8mm's aperture ring goes from f/3.5 down to f/22 in third-stop increments, though you can set it to the A position if you prefer to handle changes from the camera body. You need to hold down a push-button lock to switch between the A and manual control modes, but it's easy to find and use by feel alone because of its clever finger hold.

Videographers should note that there's no way to set the aperture ring for silent control. That's a shame because the XF 8mm is otherwise a fine lens for movies. Autofocus is smooth and quiet, and there's no visible focus breathing. The lens omits optical stabilization though, so you still need to get a gimbal or tripod for smooth footage. Pairing it with a camera that has IBIS is also a good idea.

The XF 8mm focuses as close as 7.1 inches away from the sensor, which ends up being just a few inches from the front element. This showing is slightly disappointing though because other lenses like the Laowa 9mm Zero-D get much closer (4.8 inches). Yes, a minimum focus distance of 7.1 inches is fine for some close-up captures, but don't expect macro-like results.

XF 8mm F3.5 R WR: In the Lab

I used Imatest software to check the XF 8mm's resolution and distortion characteristics after attaching it to the 26MP X-S20. The lens turns in very good results wide-open (2,550 lines) and hits excellent marks for a 26MP chip starting at f/4 (2,800 lines). From f/5.6-11, it nets outstanding resolution (3,200 lines).

Diffraction cuts into picture quality at f/16-22. Although landscape photogs love using the smallest settings of a lens for sunstars, the XF 8mm is not, pardon the pun, an all-star. It draws small points of light as multipoint starbursts at its smallest f-stops, but the tines are somewhat mushy. The XF 10-24mm and 8-16mm zooms do better if you are after this look.

Digital correction is integral to the performance of the lens. Out-of-camera JPGs show straight lines and even illumination from center to edge, but Raw images suffer from visible barrel distortion and a bit of a vignette depending on your choice of processing software. Both Adobe Lightroom Classic and Capture One Pro include correction profiles, so neither issue is difficult to deal with, however.

The optics effectively suppress false color, too. I couldn't spot any lateral chromatic aberration, which is usually visible as purple halos in very high contrast areas of an image, or longitudinal chromatic aberration, which appears as false color in defocused areas.

The short focal length limits the potential for shallow depth of focus, but you can induce some bokeh if you focus close and put some separation between your subject and background. Defocused backgrounds look soft, but they don't melt away—you need a longer lens with a brighter aperture to achieve that look.

An Ultra-Wide View for Photos and Vlogs

Considering its vast coverage, the Fujinon XF 8mm F3.5 R WR is incredibly small. You can easily throw it into a camera bag and not worry about it weighing you down on your next trip to a national park or a big city. The lens can handle the rigors of travel too, thanks to its aluminum exterior and weather protection. We lament the lack of click-free aperture control for cinema, but if you like to capture landscapes or vlog on your trips, very few other lenses can pull in as much of your surroundings. Ultimately, it gets you the same epic, wide-angle views as the 8-16mm zoom far less, thus making it a great value. Just don't count out the XF 10-24mm, which gives you wide-to-normal coverage and cleaner sunstars.
