What is the best screen for the OM-1 and the 50/2 macro lens?
What is the best screen for the OM-1 and the 50/2 macro lens?
The 2-13 and 2-4 focusing screens are clearly the best, being quite possibly the best focusing screens ever put into a camera. I have the 1-13 and 1-4n screens as well and they are very good. However, the 2-13 and 2-4 screens are MUCH better with any lens out there. The only real problem with those screens is that they are: (1) very expensive; (2) very rare; and (3) lucky owners (like me) generally feel the same way about them as the late Charleton Heston felt about his guns . . . . ("Out of my cold, dead hands . . . ." is the quote).
I disagree. For my money, the 1-4n screen is the best due to higher contrast. I had a hard (very hard) time focusing a modified 2-4 screen in an OM-2n when I had it (both the camera and the screen) and I seem to miss focus more often with the 2-13 screen in my 4T than the 1-4n screen in my OM-2. I also tend to work faster with the 1-4n screen as I'm not constantly trying to "match" vertical lines to confirm focus. With the 1-4n, once you nail focus the scene seems to jump out at you...Ken Norton of Zone 10 referred to it as a "sparkle" which is not a bad description. This is especially true when using lenses that are sharp wide open like a late SN 50/1.4.
It seems the 50/1.8 gets no respect but it appears to be a nice little lens, especially for travel.
