Due to parallax and the optical sloppiness of rangefinders and supplemental viewfinders, versus an SLR screen, at long and very short focal lengths, SLRs win. Never had trouble focusing the 19, although I do use the regular split image screen. Shoot the 19 at 5.6 (best aperture) and focus will not be an issue. BTW, Erwin says that the 21 ASPH and the 19 are toss-ups, optically. At "very great enlargement," an area where I have some experience, I would find Kodachrome 200 unusable vs. Kodachrome 64 due to the pronounced grain w/200. I have enlarged Kodachrome 64 shots to 4'x6' with beautiful results. David W.
