Brightin Star Fit 8mm f/2.8 APS-C

A 190-degree field of view and stabilization in the 79th percentile make this sub-$140 lens a standout value for Canon EF-M fisheye fun. But it's manual focus only, the aperture often locks at f/5.6, and macro performance is one of the worst we've seen at the 9th percentile. For creative wide-angle shots, it's a cheap ticket to a unique look if you can live with its quirks.

Stabilization is the surprise hero here, placing this lens well above average at the 79th percentile. It helps keep handheld fisheye shots usable, which is a godsend when you're framing such an extreme view. Aperture clocked in at the 75th percentile, but there's a catch: we can't confirm if it actually opens to f/2.8, as multiple users report a fixed f/5.6. Bokeh comes in at a solid 71st percentile, giving it a decent blur quality for a fisheye. On the flip side, optical sharpness drags it down, with center clarity that's acceptable but edges that go soft fast. That nets a 43rd percentile overall optical score, so don't expect corner-to-corner critical detail. Macro performance is abysmal at the 9th percentile, effectively a non-feature.

Stacked against the competition, this lens occupies a niche no one else touches at this price. The Tamron Di III VC 28-300mm and Sony E 18-135mm are versatile zooms with autofocus and broader focal ranges, but they're not fisheyes and cost considerably more. The Sigma Contemporary 18-50mm f/2.8 and Panasonic Leica DG Vario-Elmarit 12-35mm are sharper, faster, and more practical for everyday shooting, yet they can't touch a 190-degree view. The Nikon NIKKOR Z 17-28mm f/2.8 brings excellent wide-angle coverage with autofocus, but again, it's a standard ultra-wide, not a true fisheye. If you want a genuine fisheye on Canon EF-M, the Brightin Star undercuts everything else and gives you a shot you simply can't get with standard glass, even if you sacrifice autofocus and aperture consistency.

At a street price hovering around $140, the price-to-fun ratio is hard to fault. You get a 190-degree perspective and stabilization that most budget fisheyes lack. Just be warned: online prices are a mess, with some third-party sellers listing this lens at an absurd $28,978 (likely a data error). Stick to trusted storefronts like Amazon, where it's consistently under $150, and you're getting an affordable creative tool that punches above its pay grade for wide-angle experimentation.

The Brightin Star 7.5mm F2.8 III lands in our database with a 79th percentile stabilization score and a 71st percentile bokeh rating, both impressive for a sub-$140 lens. But the overall optical performance is just 43rd percentile, weighed down by soft edges and a fixed aperture that many users report is stuck at f/5.6, not the advertised f/2.8. For Canon EF-M mirrorless shooters, it's a manual focus affair through and through, so autofocus is off the table entirely. Still, that 190-degree field of view is a unique hook.

Autofocus-dependent shooters and video creators should pass—manual focus is a nonstarter for fast-moving scenes. Macro enthusiasts will be disappointed by the 9th percentile macro score, meaning close-up detail is a blurry mess. Travel photographers will also struggle, as the low 32.1/100 travel score underscores poor low-light performance and no weather sealing. If edge-to-edge sharpness matters, the 43rd percentile optical quality will frustrate you. This lens lives for creative fun, not critical work.

By the numbers, this lens is a rollercoaster: stabilization (79th percentile) and bokeh (71st) shine, but optical quality (43rd) and especially macro (9th) are rough. User sentiment sits at a middling 51st percentile, yet overall satisfaction is surprisingly high with a 4.2-star average across 1,280 reviews. For Canon EF-M shooters itching to try fisheye photography without a big investment, the Brightin Star 7.5mm is a scrappy, fun choice. Just know you'll be wrestling with manual focus, a wonky lens cap, and an aperture that may not do what the box says.
