Interesting. A bit strange, I see the K-1 picture has ISO 2500 and the 645 only 200. Never ebcounter so much noise @ ISO 200. Probably false information and both shot @ 2500?Michiel:
I understand. I don't use my K-1 often, but PS is worthwhile when possible. Shots below (pre-dawn) are K-1 witn 28-105mm using PS and 645Z with 80-160mm. Z shot has more resolution but the K-1 has much less noise. Approximate same angle of view in both, heavy crops.
