We have been using various Olympus (D-400- very old but good!) and Nikon models (950, 990, 995, 5000) and Canon S30 and S40 with compact Flash Cards and Smart Media cards. We provide our users with USB card readers that simplify the process of moving the images to a computer. All cameras have been used and abused on foreign programs, weekend trips, research travel and more... and none has ever failed. Otmar
