I've always been into photography but cameras are just too damn expensive. I've finally saved up a good amount of money to buy a camera with. My choices are the following: Nikon D80 Canon Rebel Xsi (Gotta wait until april) and a Canon G9. ( I know the G9 is p/s) I am looking to learn more about cameras and photography. In my opinion, I thought that in terms of price and quality, these were the best entry level cameras. Please feel free to correct me if im wrong. And please help me choose a camera... (Besides the Megapixels, I honestly don't know what else to look for. The numbers in the specs make no sense to me. Please tell me what i should be looking for) The only reason I added the G9 as an option was because you can actually put different lenses on it. I thought I should mess around with that for a few months before saving up and moving onto a DSLR. And another random question. I was browsing through different cameras. And i know there is no need for every single one of them, but do any photographers out there actually have a handful of cameras that they use? Ultimately I wish to pursue this as a pretty serious hobby but the prices of these cameras... Please recommend some books also.
