Pentax U.S. Lens focus adjustment cost?

So anyone know what it would cost to have a DA 70mm adjusted? Mine is front focusing, even with -10 adjustment on my K20D.

Working with LensAlign

No idea on cost but I'm having the same problem with the 70mm *and* the DA* 50-135mm f/2.8 lens on my K20D....wondering if this is a chronic issue with the K20D?

I purchased the LensAlign tool with the Long Ruler Kit and am currently getting my focus issues sorted out. I'd advise anybody looking to get the LensAlign tool to spring for the LRK right from the get-go (get the LensAlign Pro Plus kit). I started out with the normal Pro kit and quickly realized that the short ruler was not going to work for the distances I wanted to "focus" in on (pun intended). With the short ruler, you almost have to work at 10-20x focal length distance from the tool which is WAY closer than I use any of my lenses (mostly landscapes and nature nudes). Even 50x focal length was a little too close but at that distance the ruler became a useless blur with the DoF at that distance almost encompassing the length of the ruler making it impossible to tell where precise focus was occurring.

Personally, I think there's issues with the K20D achieving reliable auto-focus....but I first want to make sure it's either not my lenses or operator error on my part. I could show you some initial tests with the LensAlign showing inconsistent focus....I would rack and re-focus the lens three times in a row on the LensAlign target and get three different results! Got the Long Ruler Kit the other day and now I'm anxious to repeat all of my tests again.

Regards,
Terry
