The M 85mm f2.0 is a cracker of a lens. That is a good price for ***** + hood

I agree, especially when considering that the development costs for this camera will be far less than what is usual. The body and controls are K-3 III so apart from the sensor and tweaks to the processor I expect most of the work involved was rewriting the software.I think this will be a success for Pentax, even if it is fairly small scale

Thanks for that link, he explains it very well.Here's an interesting web page about the method and effects of the Bayer filter

The increased size is because the raw file contains data from all 4 discrete captures. It is only when you open the file in compatible processing software that the magic of PS resolution occurs. If you try and process the file in non-compatible software, it either won't open, or will use only one of the 4 captures to process into an image.The RAW file size is nearly 4 times (46.7 MB vs. 173MB) the non-pixel-shift version even though the image dimension in pixels is the same at 7360 x 4912 pixels.

Removing the usual RGB filter also removes the need to average over adjacent pixels so has a similar effect to pixel shift but, of course, it's only for mono not colour
Thanks for the explanation Steve, I see the connection now.Removing the usual RGB filter also removes the need to average over adjacent pixels so has a similar effect to pixel shift but, of course, it's only for mono not colour
So more accurate shades, and sharper images should be created by a monochrome camera.
Presumably the lack of the Bayer filter should have other benefits too, like a stop or two of better light gathering properties/high ISO performance ?
