Really new into the SLR stuff. Looking for some answers to some really dumb questions! 1. Is it ok to store the lens on the camera or should I take it apart when I put it in the bag? 2. Do I need a cleaning kit of some kind? My camera has a vibration dust removing thing, but what about the lens etc? 3. UV filter? Necessity? 4. Anything else I need besides camera, lens, card, and bag? thanks for the help!
