Then kodakspeak is marketing bollocks

and you should be using the commonly understood meaning of the term.

Nice camera, poor terminology

Looks an excelent piece of kit, but it's not a "full frame" sensor as you suggest. Full frame for a 645 medium format camera would be 60x45mm so that's barely over half frame for this format. That would be similar to calling an APS-C sensor full frame for for a 35mm equivalent DSLR. OK so 60x45mm sensors aren't exactly common, but that's still no reason to call this one full frame.

RE it's a crop sensor

Huh, what issues are those? OK you have an larger lens than is necessary for the sensor size but what else is there? If anything it is often an advantage to use a full image circle lens on a crop sensor, that way you are always getting the sweet spot of the image with much reduced vignetting and a possibly a more even resolution characteristic. Normally it is the non cropped sensors that show the limitations of older lenses.

40Mp CCD

That's a very nice sensor for a home astronomy setup. :)

Nice camera, nicer review...

So often tech site camera reviews are written by people that are gadget freaks first, and photographers second if at all. This writer is obviously a photographer, and her phrasing and points of inspection on this camera make this a highly worthwhile review. Kudos!

As for the camera, at that price point it is simply stunning. The sample image of the wooden fence disappearing in to the snow fields shows the DOF and detail possible with such an impressive specification and good glass.

This would seem to be a great camera for an aspiring amateur with bit of money, or a pro with little. For them the lack of a large lens selection is not a deterrent - they are not the people that buy a huge number of lenses. Those that can, will buy Leaf and Hasselblad. But for those who lack the money but are willing to spend the time and effort to work within a limited lens choice, this will be a perfect alternative...at least until Pentax can fill out the range. PLEASE Pentax would you do a great ultra wide, preferably rectalinear? (Hint: model it on the Oly 7-14mm!).
