Pros: build quality, sharpness, stabilizer

Cons: Weight

Opinion: top perspective that combined with the "top" camera like the 645z expresses its full potential. Excellent construction and choice of materials, high optical quality that expresses an extraordinary sharpness at all apertures and in all sectors. Sure it weighs ... and along with 645z formed a duet "tough" to carry but the results definitely compensate a little 'more effort. L I have proven in travel reportage and extreme flexibility in a range of well-chosen focal make it an excellent companion. From landscapes to portraits (not pushed) is a perspective that never betrays. Fantastic stabilizer which operates quietly four diaphragms. I wonder why Pentax continues to limit the optical park is the average size of the new K1 in old projects when with goals of this level shows that they can do! It is a perspective that "costs" but this parameter I consider secondary as it caters to an audience prof. from "high-end"
