I ended up going with the Tamron 70-200 2.8 G2 lens. A guy I work with has the Canon 70-200 2.8 IS lens so I rented the g2 lens and was able to compare both. There were pros and cons to both, but I really liked the Tamron a little better over all. I surprisingly get a higher keep rate on the Tamron.
