Canon 5D mark 1 comes with the Focusing Screen Ee-A. I like to have a custom grid on this screen. Is it possible to draw or maybe etch custom grid on this piece? If possible, how can we do it?
While cleaning my camera, this piece was scratched. What is its name? and is it possible to replace it?
I know this sounds crazy, but is anyone here in a habit of swapping their focusing screen between a regular (the ones shipped with the DSLRS) and a split prism screen regularly? Is is bad to keep ...
