Well....The guys and a gal from Pentax came to my shoot yesterday...They were totally chuffed to say the least. They can't wait to get their hands on the final images. The K10D worked famously. If it weren't for that frippen 2 giga card that screwed up it would have been perfect. I found myself going more and more for the 16-45 lens. I basically used the 21, 40 and 16-45. I don't think I used the 70..too long for what I wanted. I'll check my Raw's to check. I may have used it once.
I will say this. The studio assistant wants a Pentax K10D. After she saw the results, well it was over for her. She NEEDS it! It is just fine for pro application. If you are asking how does it compare to a D200..Well equal or better. Less noise and what an incredible user interface. I still have to get used to going for the 4 way toggle for choosing my focus point. It is a question of time. Been using Canon for years. It's like changing girlfriends..oooppppsss sorry..
Banding..NNNOOOOOOO. Noise.....NNNNOOOOOO. Sharp....YESSSSSS. In fact, for the Pentax, I have reduced my unsharp mask to around 200 to 240 at .3 pixels. I do have sharpen at 25 in Camera Raw however...None the less, if you have any questions..You Know!
