Originally posted by Daveinozbikes Brian it appears you have a fair bit of front focus...try it on -2 or -3. As the man said..costs nothing to play!!!
I tried using the K20s AF Adjustment feature using every setting from - 10 through +5 and while I can get a slight improvements of various amounts on closer shots, anything from about 8-10'+ in the 50-75mm range
that the camera says is in focus shows up very soft on screen or printed.
Customer service, apparently doesn't much care what happens if you're not using a Pentax lens on one of their cameras. Their rather dismissive response about what they'd suggest was, "We don't test our cameras with other manufacturers' lenses ... I suggest you contact Tamron to find out if their lens can be made to work on the K20D."
I've done that and will see what Tamron says, but I hope this isn't typical of Pentax customer service. And if it's typical of the industry, then it's probably our fault as consumers for buying into this kind of noblesse oblige.
And please don't flame me with the customary "if you don't like it, leave, who cares" responses.
