Tamron 28-75 f:2.8 performance

The replacement Tamron 28-75 arrived today from KEH, and there is a big difference compard with the first sample of this lens

f:5.6



f:2.8

To me, the difference between f:2.8 and f:5.6 with this lens is negligible, so it's a winner. From what I can see, it's a little sharper than the Sigma 24-70 that I had.

Thanks to KEH for helping me out with the lens, three months after I purchased the initial copy.
