Viltrox Air AF 9mm f/2.8 Air 9mm
Delivering a 113.8° field of view, bright f/2.8 aperture, and a 0.13m minimum focus distance, this 9mm prime excels at dramatic close-up wide-angle shots. Its optical design uses 2 aspherical and 3 ED elements for edge-to-edge sharpness, while the autofocus reliably tracks eyes and faces. It's best for macro-focused wide-angle photographers and vloggers needing immersive, exaggerated perspectives in tight interiors or landscapes.

The 30-Second Version

实测数据
Performance
That macro score is the story here. The lens is practically touching the subject at its minimum focus distance, producing exaggerated perspectives and sharp detail that our database shows as best-in-class. The 13-element optical design with aspherical and ED glass does a decent job controlling distortion and fringing, though optical performance overall lands at the 54th percentile, so it's solid but not class-leading. For everyday shooting, the f/2.8 aperture is well above average in this category, giving you some low-light flexibility and a bit of background blur, even if bokeh quality is just okay. Autofocus with Eye/Face Detection is quiet and accurate enough to stay around the middle of the pack, and the built-in stabilization helps with handheld video, ranking in the top quarter of lenses we track.

vs Competition
The Sigma 16mm f/1.4 is a natural rival, offering a much faster aperture for low light and subject separation, but it's nowhere near as wide. If you need that 9mm field of view for architecture or environmental vlogging, the Viltrox gives you an angle the Sigma simply can't. The Fujifilm XF 35mm F2 XC is sharper overall but cropped tight in comparison. For pure macro, the Viltrox's 0.13m focus distance smokes most competitors. Its stabilization also puts it ahead of many budget primes for video work.

Overview
Viltrox's 9mm F2.8 lands in the 99th percentile for macro performance, which is wild for an ultra-wide lens. You can focus down to just 0.13m, letting you get stupidly close to subjects while still pulling in a huge 113.8° field of view. That combination opens up creative shots you can't really get anywhere else at this price point. At 414g it's not a featherweight, and build quality sits in the 43rd percentile, so don't expect premium feel.
Common Questions
Q: Will this autofocus well on older Fujifilm bodies like the X-T2?
Autofocus performance is solidly average for its class, ranking at the 54th percentile. It will work fine on older bodies, but Eye/Face Detection may be slower than on newer X-Processor 5 cameras like the X-T5 or X-H2.
Q: How close can I really get? Is it true macro?
Yes, it focuses down to 0.13m (about 5 inches), giving it a macro score in the 99th percentile of lenses we track. You won't get 1:1 reproduction, but you can fill the frame with small subjects in a way no other ultra-wide prime can.
Q: Is the F2.8 enough for astrophotography?
The F2.8 aperture is well above average for ultra-wide lenses, ranking in the 73rd percentile. It can capture the Milky Way with a high ISO, but you'll want a tripod since it's not as bright as dedicated astro lenses at f/1.4 or f/2.
Who Should Skip This
Skip this if you prioritize build quality or a tactile aperture ring, as it languishes in the 43rd percentile for construction and lacks the physical controls Fuji shooters love. Travelers might also look elsewhere, portability is its weakest area at just the 41st percentile, and 414g gets noticeable on long days. If you don't need the extreme wide angle or close-up capability, a more general prime will likely suit you better.
Verdict
If you're a Fuji X-mount shooter who wants to explore macro with an ultra-wide twist, this lens delivers a rare combo that tops our charts. The build won't wow you, and the missing aperture ring may frustrate purists, but the images you'll get in return are worth it, especially when you find it at the right price.
