I was checking what is available from Canon for 5D MKII as a help for MF lenses. It looks like people only refer to EG-s.
I was in touch with ZEISS in Germany and this is what they highlighted as a problems with EG-s:
"the EF-s type screen is the only screen Canon offers for the 5DMkII. But it has no focusing aids (split-screen image, microprism collar) so it does not give you advantages compared to the standard focusing screen."
What is the best solution available for Canon 5D MKII?
Thanks for suggestion.
