Viltrox Air AF 9mm F2.8 E 9mm

A stupidly good ultra-wide prime for the money. Sharp, tiny, and all metal, but the noisy AF means video shooters should stay away.

Sharpness wide open at f/2.8 is genuinely impressive, and it only gets better stopped down. The STM autofocus is snappy and accurate for stills, landing in the 86th percentile among all lenses we track. But here's the thing: that same motor is noisy enough that video shooters will hear it whirring away in quiet scenes, which explains the lens's weak 55.3 video score. The HD nano coating does its job suppressing flare, though you'll spot some purple fringing in high-contrast edges if you go looking for it.

The obvious competitor is a zoom like the Tamron 18-300mm, which gives you way more versatility but can't touch the Viltrox for sheer wide-angle drama or low-light capability at the wide end. The Meike 50mm f/1.8 is another budget prime, but it's a totally different focal length for portraits, not landscapes. If you need an ultra-wide on APS-C and don't want to sell a kidney for Sony's 10-20mm f/4, this Viltrox is the smart money move.

We're seeing prices all over the map, from $159 to an absurd $3602, so shop smart. The real price is the low end, and at that number, this lens is an absolute steal. It delivers optical quality and build that compete with glass costing hundreds more. If you're paying anything over $250, you're getting ripped off, go find a better listing.

The Viltrox Air AF 9mm f/2.8 is the ultra-wide prime that makes you question why you'd spend three times as much on a first-party lens. At 175 grams, it's so light you'll forget it's on your camera, and the 13.5mm full-frame equivalent field of view is gloriously wide for landscapes, cramped interiors, and street scenes where you want everything in the frame. It's not perfect, but for the price, it's a little bit of a miracle.

If you're primarily a video shooter or vlogger, this isn't your lens. The noisy autofocus will contaminate your audio, and the lack of stabilization makes handheld footage jittery. Grab something like Sony's 10-20mm f/4 PZ instead, it's built for that job.

For stills shooters who want an ultra-wide perspective without the back pain or the credit card debt, this lens is a no-brainer. It's sharp, tiny, and built like a little tank. Just know that if video is your main thing, the noisy autofocus will drive you nuts. Buy it for photos, love it for the price, and leave the vlogging to a quieter lens.
