Originally posted by dlh Since you're invested in a lot of APS-C glass, and presumably don't want to have to go out and buy all new and more expensive FF lenses, I'd suggest you get a KP. The finer pixel pitch on its sensor makes it pretty much equal to the K-1 in image quality. It lacks a few features, such as the built-in GPS (it can do "astrotracer" if you buy the separate GPS module), but if you get the battery grip for it, which will accommodate the larger K-1 battery, you can take pictures for a really long time without thinking about the battery.
I feel like the K-1 is an industrial strength workhorse, but the KP is nimble, flexible, and easier to use. (Keep in mind this is an expression of "feeling", not analysis.)
This makes a lot of sense to me, and lately the price has been amazing for a premium-built beauty like the KP certainly is. It does not have a couple of the on-body controls of a flagship model like the K-5, but it atones for that by having programmable buttons, and also having a new, and very useful system of controls on top with new features. Because of this design and its compactness, no room for a top LCD, but the pull-out rear screen is sure nice when working from a low or high position. The camera's processing engine for out-of-camera JPEG images is exceptional- very fine imaging. I got mine in silver, and I love it.

Of course, there can be no DSLR as lightweight as most of the 35mm film bodies, even well-built metal bodied like the Super Program or the AF model, the MZ-S, but the KP comes the closest in its compact design with accompanying fine construction. As to the K-1, some comments allude to the K-1 being not much different to a K-5 or K-3, while in reality as shown in the illustration above, it is over 1/2 lb. heavier than a K-5, while the KP is about 2 oz. lighter. That is very substantial. I notice even that 2 oz. difference quite distinctly. Since you enjoy the feel, etc of your Super Program (I have one also, as well as the MZ-S and other AF bodies) you will probably appreciate the design concept of the KP! Its modular design with different grips and a battery grip, allows the user to change its design to accommodate various specific needs and situations. A very unique DSLR.
You will no doubt find its superior imaging to be quite a noticeable improvement, even over your very good K-5. This is yet more likely in view of your having some very fine DA glass, from what you have indicated.
