How do I do this, What do I need? All I have in my posession is the camera body, batteries, and memory cards but I dont have anything else. I am in the process of buying a 18-55mm IS lens so I am mainly wondering what other things do i need? I'm going to start with only one lens for now. other than lenses and a camera bag, what else do i need? I know i need the software but I dont know what type (if there is a certain type specially for my camera). If you could give me tips on what cites I could find these things (possibly as cheap as possible, but good quality) that would be great.
