And also

As with other Pentax DSLRs, not only is image stabilisation built into the body, but so is the autofocus motor, allowing you to use any old pentax AF lens without modification.

Sorry

Misread your post - didn't see the AF in "any old AF lens."

Consequently mine has.

Really 12.4?

The full-res photos don't seem all that sharp. About only high frequency components that I could find in Photoshop was noise. It reminds me of some research in the 90s on how to upsample media in ways that trick the brain into seeing a higher resolution image. I recall that high frequency noise was used to mask lost details, then your brain would then replace that noise with a very convincing assumption about what the details should be.

The high ISO photos look great. There's relatively little noise and noise suppression damage. Put a bright lens on it and take it into town at dusk.

Are you sure?

Same for Minolta^H^H^H^H Sony

...who first came up with the idea six years ago in the Dynax 7D.

I see Pentax, along with Canon and Nikon, are still stuck in the 1930's when it comes to flash mounts though.
