My wife has been involved in photography for quite sometime now. I assist her on occasion and it appears it is time she either upgraded her DSLR and/or got backup. She is currently using a 7D, which she raves about. Can anyone here please maybe give me a feeler on what I should be looking for her for a upgrade or a backup? Im buying it as a gift for her. I was thinking maybe keep the 7D as a backup and buy her a 5DM2, or even just buy her a T3i as a backup. Any suggestions is greatly appreciated. Her primary focus is portraits and sports..
