I use an Olympus 35mm. I paid $120 dollars for it 10 years ago. Has a 10 second timer and a tripod mounting screw on the bottom. I carry one of those 6" adjustable tripods for taking timer pictures. it is very small and pretty flat so fits well in the outer pocket of my day pack.

Usually take appx 10 pictures of an animal. Usually get one or two good ones out of the bunch. I normally use 100asa film or 200 if I know the weather is going to be dark and dreary to try to get the best quality photo I can.

For me the photos are a major addition to a good hunt and would never trust them to an instant camera. If I happen to get a good animal I always get an 8x10 blown up and hang on the wall.
I don' t know for sure but I do not believe you can get good quality enlargements from the disposable camera photos. Just my opinion.

I' m with the rest of you guys however, noway I would carry an expensive camera out on a hunting trip. Just one more thing to keep track of and worry about.
