The people at Pentax Forums created their first review of the K-5 camera.
Overall it’s pretty good. I especially found the comparison to the K-7 helpful in seeing just how much of an improvement the K-5 is. Besides the obvious improvements, I’d say what is nicest about the K-5 is that Pentax is giving users more control. 5 user modes, two auto-focus priority settings for AF.S/AF.C, raw button can now be a custom function button, and ISO noise reduction can be controlled individually, auto-align in HDR mode.
