K10D and K20D under tungsten/fluorescent light

I managed to do some AF test w/ K10D and K20D under both fluorescent light and tungsten light. Seems both camera can focus properly under fluorescent light, but both have FF problem under tungsten light:

K10D+FA77 @F1.8 under fluorescent light:

K20D+FA77 @F1.8 under fluorescent light:

K10D+FA77 @F1.8 under tungsten light:

K20D+FA77 @F1.8 under tungsten light:

A tripod was used to take all the photos. All photos are 100% center crops.

Luckily I don't take photos under tungsten light that often ...
