In which case, you'd simply set it back to default and you're back to square one, surely? No better - or worse - off than when you started.

You are correct of course. But call me old fashioned, I have always found it best to establish the actual fault first before attempting a fix.

. I now know how to figure out whether i need to adjust up or down. The basic question i have is HOW to make that adjustment. I see it on the C4 menu screen (#27 AF fine adjustment) but can't figure out how to move it + or - on the scale. The 4 way navigation bar moves the menu to #26 or #28. How do you make the lens adjustment?

Don't have your camera , but on my K1 you need to use the down button first, then use the right/left buttons to dial in correction.

Mov to the right + to correct back focus, or to the left - to correct front focus.
