My E-P1 is on the way and, quite frankly, I'm new to everything photography related. I have read and re-read many posts and blogs, but wondered about a few beginner aspects. I got the zoom lens kit, a 50mm OM and 58mm Minolta legacy off ebay (along with adapters) and plan on ordering a spare battery. Other than a case and lcd protector, is there anything essential that I'm missing? I know some people use a UV filter, but I haven't ordered one and wondered if they are necessary? I don't have a tripod, but plan on this being a hand-held shooter. I hope this hasn't been beaten to death already. I looked for a beginners thread but didn't find one. Thanks, Lee Almost forgot . . . I'm a Mac user. Will iPhoto be ok for RAW files, or do I need to step up to something better?
