Haven't had any grief at all, but definitely interest. I've had one old pro who told me some war stories from back in the day, explained that he could never "go back", but he respected the fact that my choice differed from his.
I've been lucky perhaps in finding a local photo group which isn't chock full of photo gear heads. Just people who enjoy photography. I seem to have been dubbed the resident B&W expert (God 'elp 'em LOL!) and we even had a "film inspired" photo walk with limits set on number of shots per card, ISO changes and no chimping allowed. I may even have inspired a couple of others to at least run a roll through their old film cameras one in a while.
So, to date, all positive.
