Well now I have two whole prime lenses.....the 50mm and now a Tamron 90mm f/2.8 macro.
Read lots of reviews and got a good price on local craig's list for a barely used one.
I played with it a little and now I know how hard it is to get that dof right with a macro shot as can be seen in these examples.
Also, if anyone is looking for a nikon 18-135, which I still think is an excellent walk around lens, I'll be selling one on ebay starting on Sunday and whatever I get from it will be going to Greg's fundraiser.
