Originally posted by normhead If you look at the regard the Sigma, Tamron, Nikon, and Canon 70-200s have earned, this is a lens they have to get right. And as Pentax improves the AF system, this lens will have to be able to meet those standards, not just current ones. It's not good they didn't get it right the first time, but releasing a dud won't help.
As already discussed, behind any performance or production process improvement, is the fact that any release prior to the FF release would not make much sense.
Better wait for the lens tests to be conducted with FF body...
