[quote:3496ace15f="Horst]Why should that be rubbish. On the contrary. My example was to show, that to get the same resolution as the current Pentax APS-C A 37mP are required.

Regards, Horst[/quote]The pixel density is much lower than that of the 36.3 MP Nikon D800 as the 645D sensor is 44 x 33mm as opposed to 35.9 x 24mm

So if you want to keep the same quality as present you should have about 37mP on a FF sensor.

Absolutely, hence Nikons D800 with 36.3 MP, putting 24 MP in APS-c is futile as you have reached the limits of lens resolution at 16 MP or there abouts.

Personally I think the CCD sensor of the K10D has far better colour fidelity than later CMOS censors, I still use the K10D on occasion for Macro shots of flora and fauna for that reason, fitted with a Tamron 90mm Di one of my favourite lenses.
