The accelerator starts at ISO640.

I haven't done any AF tracking since I have it, so I can't tell for AF tracking. For AF.S the speed is the same, the K1II is maybe slightly better to lock focus in the dark vs K1, from what I've tried but maybe it's subjective, anyway if there is a difference in AFS it's not striking.
Originally posted by Sperdynamite I think the Pentax implementation of pixel shift makes for an ideal scanner, but in these conditions I'd prefer if there was as little in camera noise suppression as possible-understanding that noise with PS and at low ISO is already minimal...
PS doesn't work with moving subjects. It it is about using PS or dynamic PS to remove noise on stills in poor light (high ISO), at high ISO on the K1 II the accelerator is active even with PS and dynamic PS, so you wouldn't expect the best sharpness at high ISO anyway. But shooting a castle at night without a tripod with dynamic pixel shift will deliver an image quality that no other FF DSLR can match (given that the castle will not move, usually they don't ..)
