DCRP Review: Pentax K10D
I found this to be a very fair and accruate review of the camera unlike some of the other reviews I have read. One wonders how much time some reviewer's really spend with a camera in real picture taking situations.
I particularly like the fact the this review, when dealing with a less than perfect performance in some area, does point out that in many instances the camera's settings can be used to correct the perceived problem.
All in all this review mirrors my own experience with my new K10D.
Check out the gallery photos and especially the seagulls in the shot of Alcatraz in San Francisco Harbor.
