One of the most useful things Erwin ever posted was the analysis of the "probable" focusing accuracy of said RFDR.... I didn't save it, maybe someone else has it.....but it confirmed what we leica users new 20 years ago -- empirically, of course... For example, I shoot a LOT with a 90 Summicron (old style/and current) I can hit 2 out of 3 on a good day, wide open, at less than 15 feet or so....wide open....but it's still a crap shoot at wider than f2.8 or 4....unless you're 40 feet, then no problem....portraits are a nightmare with a 90 f2 or 75 1.4 at 6-7 feet! Give me FAST normal to wide lenses on the Leica, and a 105 1.8 on the Nikon with a brightscreen....
