I read a recent hands on test with the Pentax 17-70 (was interested in replacing my 18-55)
It was found that it performed dismally wide open to 5.6 but excellent between f8-11 and would be interested in how it compares to the Sigma.
I expect a lens of this quality to perform excellent from its widest aperture or at the least 1 stop down.
The 18-55 is amazing at 5.6 to 8 and have not seen any shots from even the 16-50 or 16-45 to sway me (although I wish they did)
On the other hand the 50-135 shows me the kinda PQ I am willing to pay for.
I would keep the 50-200 as it has really good PQ for its price.
