They're very sharp images - I wonder how much of that is down to the lens rather than the camera itself. While I have no complaints with my Kx, I don't recall any of my images jumping out at me as being that sharp, leaving aside subject matter. Have you done much (or any) post-processing on them?
I started with the RAW files in Lightroom, where I adjusted WB, reduced noise and applied a grad filter from the top to reduce exposure slightly and increase contrast. Then the images were exported to CS5. The images have then had a general levels adjustment, with the lower part of this adjustment erased by about 40% using a large soft-edged brush (a general levels adjustment often makes the bottom of the images too dark).. Then I made selective levels adjustments using feathered masks (between 20 and 60 pixels depending on the size of the area) on different parts of the images. I then used an unsharp mask at a large radius (40 pixels and amount about 30-50) , using a heavily feathered mask (about 100 pixels), on the middle and far parts of the image, which reduces haze by increasing contrast. A few of the images have also had the saturation of the blue channel reduced slightly in the distance, again using a heavily feathered mask, to get rid of a touch of the blue cast you always get from altitude. All these adjusrments need careful fiddling to get them to blend into each other. Sometimes I tweak the individual masks by erasing parts of them using a soft-edged eraser at various opacities.The whole process perhaps sounds tedious but it generally takes about 10 minutes per image. Finally they are sharpened conventionally using unsharp mask.

The first shows K2 in the distance. All taken with my FA 24-90mm. Larger versions can be seen on my Flickr stream.
