Digital Camera Info.com has compiled a full measurbation review/test on the K-30. The test consists of 24 sections and some sections are further divided into several sub-sections for even more measurbations! :-o
You can begin with the first "samples" section here, where the shootout against K-5, Nikon D5100, Canon Rebel T3i and Sony A55 begins! At the first glance, I am impressed with the noise and the level of details retained with the Pentax cameras, whilst the colour rendition of the K-5 images seems to be more vivid and "purer" but the noise control of the K-30 at high ISO seems to be better.
I have decided to give up on further commenting on the rest of the tests and it is just too detailed! :-o Just go read yourself and go figure out anything whatever you could find or interpret! So, my this blog post would just end here! :-D
