I shoot snow crystals with a 50mm on a bellows, reverse mounted lens
preferred. Those crystals are a lot smaller than a camera. Who'd want to
take a macro picture of a camera?

50mm lenses are way too short to use on bellows, they only allow
super high magnifications, general purpose macro is out of the
question with them, thats why most dedication bellows lenses are
100mm not 50mm.
You are right on that, but there is no need to use bellows for any
general purpose macro shots.

The 1.7 50's are the sharpest of the three designs and have the flattest
field of focus, not as flat as a dedicated copy lens, but they're the
recommended lens for use with the Pentax Auto bellows, that is if you
can't find one of the dedicated bellows lenses of course.
I've used an SMC M50 1.7 for snow crystals and it has been good, better
than my sample of the A 50 1.4 and better then the M 50 F2. But it was
not as good (by far) as the M 50mm f4 macro. The SIgma EX 50mm f2.8 is
also better. The M 50 f4 is probably the best macro lens I've used for
extreme magnification, but it is dark and hard to focus on a foot or so
of extension.
