In the forty-odd years that I have have been shooting with MF gear (film at first, obviously, now digital) I have very rarely met another photographer using MF. At work I used to use MF for site recording and we also used it for aerial photography. But outside of that, 35mm ruled. And when I started, MF was not particularly expensive. You could pick up a Yashica 124G for about £65, or a Bronica kit for not much more and get great results.
So this scarcity of MF photographers is nothing new. If we go back thirty years, the only time you would ever see a Hasselblad would be at a wedding. That's why this forum is a great place to come and discuss a whole range of MF issues with very experienced users, because there certainly won't be many of them down at your local photo club.
