That's correct - but the same lens model, even if its a different copy of it.
Unfortunately the User's Manual reads like a prescription but no clear explanation of what the function actually does.
Originally posted by Tom Lee Also, do you know what the increments are on the adjustment screen? They go from 1-10,. but 1-10 what? Inches, centimeters?
Sorry to come back to you with all this, but just wanted to be sure I understand it all. Thank you very much for your replies.

As far as I can see, its an arbitrary scale.
+/- 1 hardly makes any visible difference, while +/- 10 is quite a visible change.
-negative adjustment is for Front Focus problems(the lens is focusing nearer than intended) +positive adjustment is for Back Focus - the lens is focusing further than intended).
Be Careful using this function. Use a focus test chart, set on a tripod, focus in good light. Controlled and repeatable conditions, a bit like a science experiment.
Many times what a user thinks is a Back or Front Focus problem is simply the camera focusing on a different object from what was intended - because its bigger, nearer, brighter, more contrasty etc. The centre focus is not really a small area, and if you have a mixture of near and far objects around it, its easy for the AF to get confused.
I hear the K-7 has improved on this - looking forward to it.
