FF & BF adjustment image

[berry]

Found this, talking about FF and BF. I have downloaded the picture and use to check the FF/BF problems, it works. Maybe useful for those whom have the K20D, which have the lens adjustment.

Thanks Berry for the info. Just tried w/ my DA*1650 lens on the K20D, worked pretty well. Now it's spot on from 16mm to 50mm

You can use debug mode to do AF adjustment on the K100D (at your own risk )

If your lens is spot on, you will see cross hair circle on the photo taken, if not, you only can see one out of focus circle in the center.

Thanks for this piece of wonderful information.

This is so much easier to test if our lens back or front focus!!
