Another option to consider might be the Tokina 100mm 2.8 Macro. Ours is the Canon-fit version; it is a very good lens. I bought my Canon 2.8L Macro because I wanted a weather/dust-resistant 100mm with Image Stabilization, to use at work, not because the Tokina was lacking as a macro lens. For macro and short telephoto, shot on my own time, I still like the Tokina, and may well purchase the Nikon-fit version.
This is not an indication of prejudice against Tamron! My wife uses an 18-200mm Tamron regularly on her D7000, and we have a Canon-fit version as well, for the times she shoots one of the Canon cameras.
