I bought the EF-S screen for the 40D, which I use regularly, but I don't notice much difference from the EF-D stock screen. The VF is a little brighter and the DOF preview seems more accurate, but that's about it. (using 2.8 or faster)


The Katz system seems to have everything I want, so I'm looking for some feedback - is it really like a rangefinder (split-screen/prism)? Is their "OptiBrite" finish worth getting? etc. whatever you'd like to share will be much appreciated.


I've read their metering guidelines and I don't anticipate any problems, just an adjustment. I shoot RAW and expose for a right-centered histogram, so I always do test shots anyway.


So - anyone use the Katz system? What do you think of it?
