This is a highly competitive & with high expectations for camera features, quality, design, etc. The design engineers have done a great job in putting Pentax in a glorious quality spot. In the real world, choices are aplenty and they are bound to be acceptable to many categories of users. Bearing this in mind, it is sad to say that this K-01 design if placed side by side with the others, it will be overlooked as a piece of cheapskate. Miniaturization, high perceived value with quality is the way forward. It is simply not appealing because it does not look serious and it is thick and bulky obviously by comparison difference with the others. I know the quality is highly acceptable as being tested by DxOMark but I am sure not buying it. I am really curious to know at the end of the day, the number of K-01 units can be sold worldwide.
Nothing much to ask for, for this is not a Nikon D7000 or a Canon 60D. Overall it is acceptable. Good performance.
