Top Selling Digital Cameras. Interesting to look at this — at Amazon.com, clearly weighted towards the $150-300 price range. 6 Canon, 5 Sony, 4 Olympus, 3 Kodak, 3 Fujifilm, 2 Minolta, 1 Nikon, 1 Sipix in the top 25. The Walmart top seller list is a little different — 4 Canon, 3 each of Kodak, Olympus, HP, 2 each of Nikon, Vivitar, Fujifilm, and Sony, and then 1 each fo Toshiba, Meade, Concord, Minolta. I need to check some retail locations too to see what is selling.
