so christmas finally came and after the longest year of my life, i finally got my beloved canon 40D. ive still got a lot of learning to do, and a lot of buying of lenses etc, but this is what ive got in the first few days of figuring it all out (17-85 kit lens) im planning on getting the canon 50mm 1.8 this weekend, is this a good choice? any pointers and advice for a complete noob is greatly appreciated. also, how do you convert raw files to jpeg without photoshop? can you do it in iphoto somehow? ive got no clue.
