Paul Graber posted excerpts from the K-7 review (which was written by Angela Nicholson):

… she likes the camera quite a lot, finding it “extremely comfortable to hold and use”. She likes IQ and detail resolution, and unique-to-Pentax features such as built-in level adjustment. Live View now fully rounded and of genuine use. During review process, she adds latest firmware and notes improvements. But she finds a few niggling problems:-
* AF improved, but still behind Nikon and Canon
* Viewfinder not that comfortable to use and a bit gloomy
* Menu system less flexible than competitors

Also, the Canon 50D and Nikon D300 / D300S might be preferred by sports photographers for the Autofocus speed, but “… landscape, still-life and macro photographers could well prefer K-7.”
