You're right -- I identify myself as a Pentaxian, even though I use several brands of film cameras and my digital camera is a Sony.But apparently, unbeknownst, I do identify as a Fuji user, despite actually owning and using several brands of cameras
Pentax is my first and favorite, and my preferred camera for 35mm film -- though that's not entirely the case, as I use Ricoh K-mount bodies with my Pentax lenses as often as actual Pentax bodies.
Or it might just be that I like saying "Pentaxian". Maybe I'd like my Nikons better if I could call myself a Nikonian. I could be considered Mamiyan, and I'm sometimes a Minoltist, but I don't own the equipment to be Canonical or an Olympian.
