I'm pulling a photog no-no and switching from Nikon to Canon. Sold my Nikon D50 and switching to Canon 50D. I'm only purchasing one lens to start with and will be doing a few portraits with it. Plus I have a 1 year old daughter who will be the main subject. Having trouble deciding which lens I want to go with first. The 50 mm f/1.4 USM AF or the 85 mm f/1.8 USM AF??? Any suggestions? eta: when shooting portraits I shoot outdoors.
