Digital FX format K-mount

Since there are so many nice K-mount full frame lenses around I am wondering, are there any DSLRs available to use these to their full potential?

I am just starting to explore the options for my K20D and something tells me the DA lenses being optimized for it should be the best choice.

Bit of a beginner's question I know...

Not yet. Pentax only has the K20D and K200D DSLRs which are APS-C. I believe the Samsung models are equivalent.

I don't know of any other brand of DSLR that uses the K-mount.

None of other dSLR's use K-mount. But there are adapters for Canon, Olympus and Minolta/Sony Alpha, so I guess EOS 5D and 1Ds's could be used with some od K-mount lenses... Nikon D3 and D700 are afaik out of game, due to some differences in focal distance. Maybe it could work with some optically corrected adapter...

Just because the older lenses were designed for 35mm, does not mean they are not performing at their best on the crop sensor DSLR.

The bit of the lens you are not using on a DSLR is the edge. This is always the weaker part of the lens, so not a disadvantage at all. Due to the greater sensitivity to stray light/reflections in a DSLR, some of the old lenses (wide angle especially) might show more propensity to flare, so a hood is especially essential.

I have quite a few "K";M;and FA lenses, and they are terriffic on my K10.
