So...I've been wanting to buy the Tamron 24-70 f/2.8 VC for a while, but had other priorities. I've rented it for the couple of times I need a 2.8 standard zoom and it was fine, but I didn't really have time to use it extensively and of course there is copy-to-copy variation. But, I've been seeing some reports of the 5d3 outer AF points not working as well with the Tamron (vs Canon 24-70 v2), and have experienced myself that AF Servo sometimes doesn't track so well near the edge of the frame. That, however, was in crappy (and changing) lighting conditions inside where any camera (well, maybe not the 1DX) would struggle.
So, I'm probably going to be renting the Canon 24-70 v2 for next week for comparison, but I'm interested in hearing from those who own the Tamron and 5d3 to tell me about their experiences since there's currently a $100 MIR going on for it for Sept, which with my CC points back I can get for just under $1K. Less if I sell off my 2nd 24-105 which I might just do.
So has the outer AF points been a problem on the 5d3? Performance otherwise been good?
