K10D vs K20D w/ some other lenses

I also did AF comparison between these two cameras w/ some of my other lenses. All photos are 100% center crops. A tripod was used in all tests.

K10D+FA24 @ F8

K20D+FA24 @ F8

K10D+FA85 @ F1.4

K20D+FA85 @ F1.4

K10D+FA77 @ F1.8 (after AF adjustment of 150um):

K20D+FA77 @ F1.8 (no AF adjustment done):

Some other lenses need to be adjusted on my K10D but don't need to w/ the K20D:
FA31: add 80um
FA200/2.8: add 190um

Overall I feel the AF w/ K20D is much more accurate w/ all the lenses I've tested so far.

Hope this finding is helpful to some potential K20D owners

Cheers!
