canon 600D fish eye converter

hi, anyone know how i can fit this lens to my 600d?

That lens adapter is for one of the Canon Powershot series and I seriously doubt you can use it on a DSLR if that is what you are attempting to accomplish. On the Powershot series, I'll use the G2 as an example, there is a ring where the the non-removable lens meets the "boxy" part of the body. When the ring is removed threads are exposed. Sometimes a barrel shaped adapter was used and then the lens like what you have was screwed into the adapter. Canon made some "telephoto" and "wide" adapters and 3rd party manufacturers made others as you have found. The important thing was that the "normal" lens of the Powershot body was still used so it and the accessory lens became an optical system. Even if you could physically mount the accessory lens you have to a DSLR, you would not have the additional lens elements that are part of the Powershot body.

I would suggest you repost this over on the Powershot forum should you want to learn more. Perhaps even it for sale over in the Marketplace.

tanx for the info, I had it on a pwershot a570is but the camera broke down so now i have this lens and a 600d.
I will try something like this http://www.flickr.com …iscuss/72157594​212520387/
