would the k20d be better in autofocus speed? and high iso quality? i see now it's very low price, and selling the k10d it would be not a big sacrifice.
Landaris:
My first post to your thread was based upon my experience shooting the K20 & Tammy 17-50mm. I never shot the K10. But I so often read that the K10's AF is "nearly identical" to the K20s. Based on this, I thought it notewothy to offer my opinion.
I think it is generally accepted that the K20 offers at least a stop of better ISO performance than does the K10. Again, I have not shot the K10, but most reviews and most of the opinions I encounter point to this. Best of luck.
