Lens design happens in software, lens testing happens on an optical
bench not a camera.

Having time for my idle brain to get into mischief, I got to
wondering how Pentax designs and tests the D FA lenses without
having a full-frame (24 x 36 mm) camera to test them on.
Do they use the two (or so) prototypes of the MZ-D that they must
still have?
Do they use full-frame Canons with a lens adapter?
Do they have a non-camera setup -- that is, a stationary box with a
24 x 36 mm. sensor, shutter, and lens mount? This solution seems
most likely.
Any thoughts?
