I spent $130 on the camera I am using now. I'm looking to spend no more than $600 on a camera at the moment. I don't care if it's used or not. I just need a camera that can use multiple lenses, and that's why I was thinking something Nikon since they apparently can take lenses made from years ago. I don't care if it has auto-focusing or not, rather do it all manually actually. I guess what I'm looking for is a camera that has the ability to take photos with a nice DOF without being so darn close to the subject like I have to when I use my current camera. What I would really like is a D90 but my budget isn't that great. I can't even afford the body at the moment let alone lenses, a tripod, speed lights, etc. I realize I could go to ebay to look for cheap-priced used cameras. What are my choices for camera models?
