I got some good manual focusing lenses and looking for a suitable focusing screen. Focusing screen E-A, E-B, E-L could fit the bill but they are very difficult to find it in ebay.
Other focusing screens I can find for realatively cheaper price are E-D and E-I. May I ask how easy to focus with E-D?
In my instruction manual there isn't an E focusing screen, maybe you intended H , there is H screen,
anyway i have C and D , D has the grid but you have to focus looking just at the ground glass so
is needed a little training to focus without a split image.
I have two 650 and one 630 eos but in one of the 650 autofocus doesn't work so i'm planning to buy the
L screen for that camera to use with manual focus , L screen is splitted i 4 parts , i think is the best
as gives vertical and horizontal alignement .
