I bought a Tamron 28-75 f2.8 a while back, I picked the Tamron over equivalent Canon (24-70L) because many reviews claimed it to be sharper... But mostly because it was a third the cost.
Anyway! I took 4 pictures at f11, f5.6, f4 and f2.8. 11, 5.6, and 4 look fantastic but f2.8 looks horrible. All were tripod shot at a relatively low ISO from a 40D. Then I did a 100% crop
My question is: is 2.8 bad enough that this might be a bad copy or am I expecting too much.
