I just got a budget to buy a camera for the college, mostly for my use so I'm not using my own equipment. I've taken a couple thousand pics using my own gear since I've been here and it's only been a couple of months. So I requested that the school buy some gear for me like they have for the other campus photogs. My budget was $7k, so I went with a gripped MkIII, the Tamron 24-70 2.8, and the Tamron 70-200 2.8. With extra batteries, a couple good CF cards, and a nice Glass Taxi bag, I just squeaked in under budget.
The Canon lenses in those ranges would have blown my budget to pieces. The two Tamrons both have excellent reviews and pretty damn near Canon's IQ. Now I just have to wait. I understand the purchasing process here can be interminable.
