Re: [OM] Beattie 1-3 (82402) vs Olympus 2-13 focusing screen

Different strokes for different folks. I like the way the 2-13 
microprism 'collar' area disappears when in focus. I have a Beattie 
all-matte in the OM-4 and a 2-13 in the 4Ti. They are both brighter than 
the 1 series screens and both work well for me. Using different screens 
lets me know which viewfinder I'm looking through.
I've never made a brightness comparison between them. Given the ability 
of the human eye to adjust to light, I'm not sure a subjective 
comparison would tell much. I guess putting 2 cameras side by side with 
identical lenses might show a difference? The real test woud be to put 
each in an OM-1 or 2 (which read brightness from the focusing screen) 
with a fixed light source and compare the meter readings. Trouble is, 
the 2-13 screen has to have part of it's tab filed off to fit the 
earlier cameras adn I don't feel like doing that to mine. Anybody want 
to donate a 2-4 or 2-13 screen for scientific investigation, just send 
it on and I'll post the results  ;-) ! Spare Beatties welcome as well :-D  !
