I’ve added the 75mm crops to the Tamron/Sony 28-75mm F/2.8 comparison page. Some people are going to get mad when they see the crops, but I can assure you I re-shot the 75mm test sets several times just to make sure focusing was as perfect as possible on each lens. I also evaluated the focusing speed and accuracy, and found little to no difference between the two using the A900.
I’ll add some center and corner crops from the Sony Carl Zeiss 24-70mm F/2.8 in a couple of days, so check back. Based on what I’ve seen so far, this comparison will also make some people mad!
