Does...Fully automatic 35mm autofocus SLR camera mean that this camera is only usable in autofocus mode? I'm going to be taking an intro to photography class this coming semester and we need a manual camera. I saw this on the possible camera I might be getting for x-mas. Am I out of luck here? Also, will a camera that does have both auto and manual focus, will it work just fine in manual focus compared to auto? I don't want to get a camera that I can't use for this class. Thanks for the help!
