Yes! I rec'd my camera last Thursday and finally had a chance to play around with it over the weekend. The only caveat is that some of the DL's functionality may not be supported by the older lenses meaning you have to do some things manually.
KAF and KAF2 lens (autofocus) are fully supported (except for the power zoom on KAF2).
KA is fully supported (program mode) but you will have to manually focus the lens.
K is supported for aperture priority through the "M" setting. Also, no autofocus is supported on K mount. You make a setting within the custom screen to permit manual aperture settings (one time until you deselect it). When you have composed the picture, you press the AEL button and the camera meters the shot for the aperture setting on the lens and sets the shutter speed automatically. It sounds more complicated that it is.
M42 screw mount lens are supported through a bayonet adapter. The process is the same as K mount except that, for convenience, you will probably focus the lens wide open and when ready to meter, manually stop down the lens and then press the AEL button to set the shutter speed and then shoot.
There are an estimated 24,000,000 lenses made for Pentax cameras, everything ranging from junk to classic primes and they all work. Many of the older lenses can be had for a song on Ebay or pawn shops and are every bit the optical equivalent (or better) than anything manufactured today.
