the same thing. AF unusable from 5.6. (tested with yet another lens)
Lens: Tamron 17-55 2.8
Im postive this is an official problem of the k30 with this Tamron lens.
How does that lead you to conclude that it is the fault of the K30? If I follow everything correctly, you have tried multiple lenses on more than one body. The only way to say for sure would be to try those same lenses on a different models of Pentax cameras.
Okay, let's suppose that it is a problem with Tamron 17-50/K30 incompatibility. (i.e. all lenses work on all other models and none work on any K30.) How does that put the onus on Pentax to remedy the situation? Pentax isn't an aftermarket body manufacturer for Tamron lenses.
