Hi -
I just replaced the regular screen in my EOS-3 with the Ec-N grid screen
since I shoot mostly landscapes. It's great for balancing the horizon and
also enforcing the rule of thirds. It's also a half a stop darker, which
makes manual focussing a little more difficult, and I wish they had stuck
in a split-screen as well. Oh well.
The EOS-3 does some magic to superimpose its focusing points on all of the
Ec-screens. So there's no problem there.
Although the viewfinder screen goes a bit darker and you need to set CF-0
to compensate for the TTL metering (which is up in the pentaprism); I
believe the focusing mechanisms are in the body behind the mirror and so
don't seem to be affected by the 1 stop of darker screen.
