K20d focus issue.
Clarky I believe if you use the focus adjustment on a Pentax lens the camera will recognise the lens and adjust accordingly. Of course it will apply the same adjustment to any Pentax lens of the same type, as it can't read the serial number. I'm not sure it works for third party lenses. It'll be in...

Thanks Gwyn. It would be a right pain if you had to go through menus each time you changed lenses :?

K20d focus issue.
I don't have a K20D, so not sure, but isn't there an option for applying the same adjustment to all lenses? it sounds as if your K20D just needs a global ~-5?

K20d focus issue.
The K20d (and K10D) recognizes third party lenses, but it sometimes sees different lenses from a given manufacturer as all the same. It comes from the fact that third party lenses are reversed engineered, so third party manufacturer sometime use the same I.D. chip in more than one lens model.

K20d focus issue.
And some older Sigma lenses incorrectly identify themselves as Pentax lenses of a similar type. For example, my Sigma UC 28-200 used to identify as a Pentax SMC 28-135.

Yes, thats right but the focus adjustment for that specific lens is retained by the K20D, even if it can't tell the difference betw...

K20d focus issue.
Can I just ask, how do you find the focus adjustment menu, and how do you know what firmware you are running? Can not find reference to either in teh K20d manual. I have performed a focus chart test, and it is ever so slightly back focussing with my DA* 16-50. No massive biggie if I can make the ...
