I think there are four camera brands that are offering ways to shoot better black and white, though I think it’s still not like shooting black and white film and sometimes you have to do some tinkering with the camera settings.
Top of my list is Olympus/OM System, both for its black and white mono profiles, via the Creative Dial on the OM-3 and on the E-P7 and PEN-F before that, and for its black and white Art Filters, which can be as wildly contrasty, grainy and ‘sooty’ as you like. You can even add borders and vignettes and toning effects, though the latter aren’t great, to be fair.
