Summary: i got this for my t3i (along wth adapter) and while it works just fine. its not fisheye on the crop sensor at least not from what i can tell. if you want the fisheye effect for a crop sensor this isnt what you want. i do like the lens as its very light and gives a different effect to pictures.
This lens is pretty awesome. I have an old Diana made before ...

Summary: Let's compare prices on KEH, shall we? Cheapest 24mm lens: $248 dollars. Cheapest fisheye lens: None for sale; usually about $300 bucks. This lens is pretty awesome. I have an old Diana made before Lomography bought the brand, so I can't use it as a system accessory. I've got it hooked up to my crotchety old Nikon F2 with the fifteen-dollar adapter, also sold by Lomography. A lot of people say there's no fisheye effect. No duh.
Summary: Product arrived in a timely manner and well packaged. However, I'm not sure if it was the adaptor or the lens with the problem, but I wasn't too satisfied with the quality. I could barely tell the picture was meant to be fisheye and the lens didn't even fit completely to the adaptor.
Summary: I use this lens in my full frame canon camera with the mount adaptor and I have good results. The focus is not really sharp, and it has some color aberrations, but this is almost what you are looking for when you invest your money in lomo lens. It's a good cheap fisheye lens to do different and cool videos and pictures.
Summary: Nice ultra wide fisheye lens! The viewfinder is helpful in composing your shot but is very close to the hotshoe thus knocking the flash a little off to the left, but not by much. Sturdy enough even though it is plastic. A fun lens to add to craziness to your photographs!
