I shoot with a Rebel XT and I would like to get in to some portrait photography. (I've mostly done sports photography for local baseball leagues and I use the Canon 70-300 IS USM for that.) I live at the beach, so I would be doing most of my work there, but I would also like to shoot some studio portraits also (I'm using the word studio loosely - I should just say indoor). From what I'm reading, everyone loves the 85mm 1.8. Would this be a good choice for me? Thanks for your help.
