It snowed a little today (got damn cold too) and I tried a few snow
crystal shots with the Q. Details and some sample shots are here:

Had some odd flare (?) or something with my standard reverse mounted
50mm setup. Better luck with with a regular mounted 50mm macro. I had
tested the AF360 flash with a Q mount lens and it worked like a charm -
even though it was bigger than the rest of the camera setup by a fair
margin. With the K mount adapter the flash seems a bit wonky, at least
per my expectations. It stays in P-TTTL mode and I can't get it to
manual mode. It will only do P-TTl or SB. I thought P-TTL would only
work if the camera was in communication with the lens's chip. While
flahs compensation worked (in that it changed the intensity of the
flash) I still had to resort to putting a hanky on the flash to control
the intensity of the light and keep everything form being blown out.
I was in "relearning" mode since it has been 2 years since I have had a
good session shooting snow crystals (last season was a bust), but things
went smoothly.
I have high hopes for this setup still. As ISO 160 the noise is pretty
much nill and the focus peaking plus the 4x MF focus assist make it much
easier to focus. Working at 1 to 2x is still much easier that 4 to 8 x.
The snow today was not very good in terms of its form, but I think the Q
will be great for this and other extreme macro stuff. I might wind up
getting the pricey Pentax K to Q converter with the built in leaf
shutter, as the sync speed of 1/13th did not help much.
