By sort of a freak accident I got a chance to buy one of these cameras today. I’ve had a Pentax *ist DS for a about a year and half. It’s been a great camera and there’s really nothing wrong with it. That doesn’t mean that it could be better.
The main selling points of the K10D is the 10Mp censor, Share Reduction and weather sealing. I want it for the 10mp and the SR.
Unfortunately I’m baby-sitting tonight, so it’s limited how much I can play with it. But I’ve been through the menus, clicked and turned all the knobs.
My first impression is that it’s quite heavy compared to the DS. And that it autofocues very, very fast, and that’s in a dimly lit apartment. Oh, and that I have to order a bigger memory card in a hurry, as the 16mb DNG files (the PEF files are 13Mb not much better, and unsupported by my raw software).
Autofocus: Even my Sigma 70-200 1:2.8 APO DG locks focus in my dimly lighted living room at 200mm and f/2.8. I’ll have to see how it does with the x2 teleconverter tomorrow. Something the DS had problem with in low light.
ISO Noise: Yes, it’s there and it’s quite visible at 1600iso. I’m not sure that it’s actually worse than the DS, but I’ll have to do tests to find out. The thing with it is that it seems more ordered and therefor more eye catching.
