Lens Distortion Fisheye HELP. Archived from groups: rec.photo.digital () I am shooting using a fisheye lens (century optics 3x fisheye) with my sony trv900. It works but i would like to know if i add distance to the fisheye lens to the CCD sensors...

really look like a fisheye on the 20D because of the sensor cropping. However it'd still probably be wide enough for my purposes. Another lens I've been looking at is the 8mm f4 Sigma. I understand this would become pretty much like a full-frame fisheye...

and actual stitching. Does anyone know if these tools would handle a fisheye lens correctly? I heard somewhere that for ultra wide, fisheye is sometimes better because it has less chromatic aberration, and the software can (apparently) correct the distortion...

some ways the "fisheye perspective" isn't as distorted as a normal wide angle lens is. With careful use on certain subjects, I almost like the look better than you get with a superwide normal type lens. People assume the only thing you can get with a fisheye...

I'm thinking of getting an old manual full fisheye lens and getting an adapter for my 10D. Sigma makes a new 8mm full fisheye, but I'd like a faster lens and I'd prefer to spend less money. Also, with that DOF I don't really think autofocus will be...
