I have a Rebel XTI with a kit lens and am looking for a new lens (or two?) Mainly I am looking for a great portrait lens, although for somewhat candid portraits. (I have two small children who are always on the move, so I usually take pictures of them when they are playing rather than having them sit for formal portraits.) I also am an avid gardener, and would love a macro lens to photograph my flowers and their winged visitors. I have looked at the 50 1.8, 50 1.4, and 50 2.5 macro reviews. I have also read the reviews for the 60 2.8 macro. My question is this: should I get a 50 2.5 macro to cover both portraits and macro (and if so, will it be quick enough inside for portraits and good enough for macros of insects?) Or should I get a 50 1.8 for portraits and a 60 2.8 for macros (which will be around $100 - $150 more than just the 50 2.5)? Or is the 50 1.4 so much better than the other 50s that I should get it despite the fact that I would then have to wait awhile for a macro lens?
