Hi Sherry. My camera preference is an old one -- a Konica Minolta DiMage G530 -- which is only 5 megapixels -- but gives me crystal-clear, highly detailed Iris pictures (if I can hold my hands still enough) with very accurate coloration. You can pick one up on Ebay now and then. When I thought my camera wasn't working anymore (it ended up only needing a new battery), I couldn't find a G530 for sale so I took a chance on the next model after the G530 -- a G600 I think, which is a 6 megapixel camera -- and it does equally a fine job for me. So it is now my back-up camera.
In the interim, I tried a CoolPix camera, but couldn't get it to give me the quality of pictures that my DiMage cameras do. FWIW.
Good luck -- hope you find something that works for you!!
