Hi everybody. I'm planning to acquire a Brightscreen focussing screen # p232, the one with microprism spot center only (no split image), to use it with a late Canon 5D mark one and Leica R lenses. Would you say that it gives in focus shots from f/1.4 to f/5.6? Do microprisms darken significantly at f/4 or f/5.6? Thanks for advice.
