I really like this film, Konica VX 400, and used to shoot quite a lot in the past. It was cheap, it could be found at any self-respecting dealer, and it was in my opinion the best of both worlds, colour and b&w. To me it was a good film, on the same level with the Ilford’s XP2 (another film I like very much).
Mind you, this film is the monochrome version of the Konica VX, which is basically a C41 monochrome film, suitable for bw processing. Not the easiest film to work with, and many do complain that the tones are not what they should be. But I like it the way it comes, kind of dramatic and old-style appearance. That orange mask is a pain, but it renders a certain something to the feeling of the image.
I process this film in bw chemistry and scan it as a regular Minox negative. Nowadays it is really hard to come by, very expensive and of course, discontinued. I still have a 8 roll brick saved, and I guess I will save it for Minox cutter. Or, who knows, perhaps I will sacrifice a roll or two for my Nikons, just for fun.
