Gb makes a good point. Unless you're going to follow the process through yourself, or you have a competent lab, the "best" lens won't do much good. Doing B&W film is one of the joys of photography, because you can do all the work yourself, except, of course, making the film. So to update my earlier post - uncoated lens, D-23 developer, and print in the darkroom. Pick your own tools, do the work yourself, and enjoy.
