I happen to really like the iq coming out of the 16-50. I agree that that quality control has not been pentax's strong suit, however,when they work pentax products produce some amazing images... The operative word being when.
Was reminded why I love pentax when I shot with a friend's D3s. That thing takes GREAT pictures, but I could not imagine holding that beast up the entire night of a wedding.
I know that's an extreme case, and there are easier FF bodies to handle (5dII), but the ergonomics on my K-5 are unsurpassed. A big deal when holding a camera for 8 hours. However, I have to seriously consider switching systems if the qc issue persists.
