Olympus OM Focusing Screens

[anerjee]

Hello,

I've been using an Om-4 Ti with a 28/85 combination, with a lot of fun. I'm thinking of adding a 50/1.2 for low light use, and hence want to check what focusing screen is optimal.

Based on the images given in this link, I have either the 1-13 or the 2-13 screen installed now. Not sure how to tell the difference between the two.

I'd like to check which screen is best suited for low light work?

thanks!

The 2-13 screen (which is very rare) says 2-13 on its mounting tab.

As for ease of focusing in low light, I used to like the 2-13 because it is noticeably brighter. But as I have gotten older, I now like the 1-2 microprism screen, because it seems to snap into focus better for me in low light.

The two would be suited with 50/1.2.
You can check which one is installed by unmount it and read.
2-13 may be brighter but the 1-13 is as good for 1.2 lens to focus accurately.
