Maybe my experience is unusual but even before autofocus I used plain  
ground glass screens for focussing. I have a grid GG screen in my R8  
and the same in my OM4Ti. I preferred not to have the obstruction  
centre screen and anyway I always thought that micro-prisms and split  
image range finders were angled to look through a f5.6 window (they  
tend to go dark at apertures slower than this) so the effective range  
finder base is rather small - though perhaps we are more sensitive to  
micro-prisms than coincident type focussing? Anybody know?
