K20D - AF adjustments - for all and for one - cumulative or not ?

Hi All,

I am reading some postings about AF adjustments for K20D now (I do not
have a camera w/ me at work) - I see some (one or two) postings stating
that if you will put AF adjustment for "all" lenses as X and for "one" lens as Y, then the resulting adjustment will be X+Y.

Is it true or not (can we go beyond "-10" and "+10" that way) ?

Please share your experience. Thx.

I'm pretty sure the manual say:

If you've choosen both AF adj. for all and for one, AF adj. for all will overrule AF adj for one.

So 10 should be the limit.

I also wonder, any good way to test if your lens need AF correction? Me and my new and very untrained dSRL eyes can't really calibrate it on "feel".

That would be good if it were true.

There isnt as much room for AF adjustment on the K20 as on the K10 hack. Would of been good if they left our options as open.

I finally reread the AF adjustment page of the K20D manual and it says if Apply All and Apply One are both set, it will use Apply All. (Read the second bullet in the gray box at the bottom on page 106)

So Karn is correct.

Karn: this ought to be the best way for you to check that.
But a warning, unless you notice problems in your images, testing can lead to insanity.
I would suggest testing only to confirm a creeping suspicion.

Manual clarifies this. Only 1 setting takes effect.
