7.5mm F2.8 Ultra Wide-Angle Fisheye Manual Focus APS-C Mirrorless Camera Lens, Fit for Canon EOS-M Mount M, M2, M3, M5, M6, M10, M100, M50, M200

This lens is well made. IQ is excellent for a cheap lens. As with any fisheye, there's significant vignetting around the edges, but that's a factor of the optics involved, not a flaw of this lens. Wide open, sharpness is a little soft, but stopped down a few steps, it's fairly crisp in the center, with a bit of softening on the edges. The coating gives a very warm cast to shots, which can be used creatively or comped out in editing.Aperture ring is unclicked, which I dislike. Video shooters will appreciate it. The focusing ring has a bit too much resistance, but it should smooth out with use. There's a small issue with the cap. It sits on the built in lens hood, and doesn't snap in at all. There's a ring of felt inside the cap that's supposed tp hold it in place with friction, but the cap comes off *very* easily. It's rattled off in my camera bag multiple times. I put some frog tape inside to provide better grip, but the hood rips it up quickly.Gotta say, this thing is built like a tank. All metal, and heavy. This lens weighs more than some of my full frame and aps-c lenses. Construction is excellent...with one major issue.The lens I recieved doesn't lock onto the body properly. The cutout for the stop pin on my M50, M, and M100 doesn't line up properly, so the lens starts to disengage when you turn the rings. I've almost dropped it right off the body several times. I'm not sure if this is a common occurrence, or I've just gotten a lens with a defect. I've started an exchange for a new one. I'll update after the replacement arrives. If it's present in all these lenses, this is a huge problem.Customer service is also nonexistent. I emailed the company before I started the amazon exchange over a week ago. Haven't heard back.UPDATE: I got the replacement soon after originally writing this review, and the defect was not present. Forgot to come back and update. I've been using it for almost a year now, and I really like it for what it is. Very well built. The action never did loosen up, but it's a minor gripe, and likely an intentional design choice as opposed to a defect. Even so, this is a great little piece of kit. You get a ton of lens for short money. If you're looking for a fisheye to play with on an M body, this is what you want.

Solid, hearty build - the quality is very high for the price point. Smooth operation, fun to use. Color rendition is very nice, it has a pleasing feel, not too vintagey or yellowed at all. Image quality is great in the center - maybe 30-40% of the frame. I see descriptions of vignetting at the edges - I wouldn't call it that. It's downright blurry at the edges (not "soft"). So, know that going in. I didn't notice so much until I moved up to higher megapixel camera, or maybe I just didn't look closely. Still, at this price, it's worth it - but beware the edges. There are competitor lenses in the same budget with much better edge rendition, if that's important.That said, still glad I have it, not looking to unload it any time soon. May try one of the longer focal lengths, as the quality is totally worth it.

Was really excited to get this and start playing with it. However, after only taking a couple shots, the focal ring stopped working.Will update once I hear back.Update: Received a replacement and it seems as sturdy as the first one did. Have yet to really get the opportunity to use it again though, so I suppose time will tell if this one will break as well.

Quality more then the price 👌

Always comes out too dark and shows way too far away

Not compatible with EOS-T6i Rebel body. Not sure if it needs an lens mount adapter.

It don't want to conect with my canon m50.The camera is not doing pictures with it :/

The lens arrived in perfect condition (and I returned it in same condition). The reason I returned it is that I found the fish-eye characteristic at 7.5mm to be too extreme for my purposes. I couldn't find a landscape/street photography use that worked for me, nor could I make use of the macro focal length either.Nothing wrong with the lens. It just didn't meet my particular photographic needs.It might be the perfect lens for some photographers (looking for a particular effect), but I could not figure out how I might get sufficient use from such a lens as to justify even such a modest price.Having said that, I was EXTREMELY impressed with the all-metal build quality and the quality of optics provided at such a reasonable price point. I will certainly look for other lenses in this brand line-up (and related brands by the same manufacturer?) as I remained very impressed with the product quality.ALSO: Jennie from Brightin Star reached out to me through Amazon with a very friendly message asking why I had returned the lens in order to get feedback. This was extremely impressive. Outstanding customer support!All of this deserves 5 stars ... even for a product I chose not to keep. Happy lens hunting!
