Artra Lab Oculilumen 10mm f/5.6 Fisheye 10mm

The Artra Lab Oculilumen 10mm f/5.6 is a tiny manual focus fisheye with a huge 172 degree view. It's best for creative and macro work, but the fixed f/5.6 aperture and no autofocus limit it to well-lit, deliberate shooting. Worth it if you can find it near USD 80.

The 10mm focal length on APS-C gives you that full 172 degree fisheye view, and the 6 element, 5 group design with multilayer coating keeps contrast decent and flares under control. Manual focus only, which is fine for a lens like this since the huge depth of field at f/5.6 means you're not constantly hunting. Minimum focus of 200mm lets you get close for exaggerated macro-style shots, and our database puts its macro performance well above average. The fixed f/5.6 aperture is the main limitation. You'll want bright daylight or a flash, and the lack of stabilization means handheld low light shots get shaky fast.

Against the Viltrox Air AF 9mm f/2.8, the Artra Lab gives you a wider fisheye view but loses autofocus and two stops of light. The 7Artisans LITE AF35mm F1.8 is a completely different beast, a fast autofocus prime for general use, not a fisheye. The Tamron Di III VC 28-300mm f/4-7.1 is a superzoom with stabilization and autofocus, far more versatile but nowhere near as wide or distorted. The Sony E PZ 16-50mm f/3.5-5.6 OSS is a kit zoom that's more practical but boring by comparison. If you want a fisheye specifically, the Artra Lab is one of the few budget options in EF-M and E mount. If you want a general purpose lens, every competitor here beats it.

Pricing is all over the place. US listings run from USD 80 to USD 150 across four vendors, so shop around before you commit. At the low end, this is a cheap ticket into fisheye photography. At the high end, you're paying a premium for a lens with no autofocus and a fixed aperture. The CAD 205 listing in Canada is on the steeper side once you factor in what you're getting. If you can snag it near USD 80, it's a fun creative tool. Near USD 150, it's harder to justify unless you specifically need this exact focal length and mount.

The Artra Lab Oculilumen 10mm f/5.6 is a tiny, manual focus fisheye for Canon EF-M and Sony E APS-C bodies. It gives you a massive 172 degree field of view in a 120g package that basically disappears on your camera. This is a specialty lens for people who want wild distortion and exaggerated perspectives, not an everyday walkaround optic.

It's fixed at f/5.6, so you need light. No autofocus, no stabilization, no weather sealing. But for fine art, experimental portraits, and creative close-ups, it delivers a look you can't get from a standard wide angle.

Skip this if you need autofocus, shoot in low light, or want a lens for wildlife and sports. The fixed f/5.6 and manual focus make fast action a frustrating experience. If you want a general purpose wide angle, the Viltrox Air AF 9mm f/2.8 gives you autofocus and a brighter aperture for not much more money.

Buy this if you're a fine art or experimental portrait photographer who wants extreme distortion and doesn't mind manual focus. It's also a fun second lens for creative close-ups and weird perspectives. The fixed f/5.6 and lack of autofocus mean it's not for casual shooters who want to point and shoot. But for the right person, it's a cheap way to get a look that's hard to replicate.
