ok, so I have a few questions and am hoping someone could please help me out. I just recently (about 2 months ago) bought a Rebel XTi and have the lens that came with it (18-55mm), also my husband bought me a lens for mothers day (70-300mm) so that's the equipment I have as of now. What lens is best for portraits? How important is it to get a flash kit? Also anything you can tell me about filters would be nice as well. I'm sorry I have all these questions, I've just never had a SLR before. My last camera was a Canon Powershot SD630 so this is all new to me. Any help would be greatly appreciated! Thank you!
