Where i am from, indeed Pentax users are a rare lot. Almost cpuld say just half a step from extinction.
I participated in a good number of photoshoots in past 5-6 months, and i have yet to encounter one single other Pentax user.
All i see of the rest are Sony, Nikon, Canon, Olympus and Fuji (not in that order in terms of number).
And every time i pull out my MZ-S (i primarily use the MZ-S, and less of the K-1, for such shoots), i will get odd looks within 10-15mins, for two reasons.
First, that i am using film, second, that i am using a camera which (1) is Pentax and there's just No One Else using any Pentax and (2) it is a Pentax which none had even heard before or know it existed.
But one thing for sure.
They all had this somewhat envious look of the FA77, as almost all think the 77 looks just so very nice.
But yes, i also get odd reactions when they learnt it is a 77mm lens (well, no one else has such an odd focal length).
So, yeah, Pentax users are bloody damn rare (although i think in Japan and Europe, probably more popular).
The day i see another Pentax user at a photoshoot i join, i think i may just go buy lottery, good chance might just strike a few thousand dollars
