Default D-100 and Sigma 8mm Shopping

I'm looking to move into the Digital SLR market and have been thinking D 100. I was told the Sigma 8mm circular fisheye produces images that are slightly chopped off and that you lose a little on the narrow side.

Can anyone validate this? I need to occasionally shoot iPIX images and have a full circular fisheye just for that purpose.

If this is true does anyone have a better suggestion?

I hope to buy a Kodak 14N a few years down the road and would like to stick with compatible hardware.

Thanks
Jim

The 8mm Sigma image will be a circular one chopped off at the top and bottom of the frame. That using a D1x/h/D100. If full frame, you'll get a circular image in the middle of the frame.

Just so I'm not confused, full frame means a full sized 35mm CCD, correct?

I'll have to search for some samples of this combination. I may still be able to get by using the D-100 in portrait mode and shooting 3 images at 120 degrees instead of two at 180.

I suppose I can practice the 3 shot method with my 990 to make sure it will work.

Thanks for the help

Here's a simulation of what I recall the viewfinder image looked like when I peered through a D1x with a Sigma 8mm fish-eye mounted on it:


This is what the same lens might provide on a film body:


I never attempted to make panoramas using images like that, perhaps a fish-eye that provides full-frame coverage would better suit you? I don't own that 8mm lens, I just peeked through one that another photog was using
