firmware1.41 is currently the best for me. FA43/1,9Limited focuses for the first time and accurately (fw1.30 and fw1.40 were not as good with FA43/1,9Limited)
test photos all on f1,9, AF-S, different distances and different light, profil Bright, JPGs from K-1, AF Adjustment -8

I'll try AF-C with DA*200/2,8 SDM, but that's not my priority, I photograph the landscape and portraits.
