Ok, I've seen quite a few photos taken with a fish eye lense. I do know that the lens and filter do differ. From what I've read, the lens gives you a "real" fisheye look and the adapter gives you a like-ness of it, but does no more than buldge the image out. For the money and because I'm poor. Is an adapter an ok solution for the money or do they kinda suck? Is the "soft focus" different from a diffuser? What kind of flash can I get for a Canon EOS 650? What is a good zoom lens for this kinda camera? Thanks.
