Hi folks, is anyone using the Brightscreen splitscreen (Number 5 in their terminology) for their Canon 5D to focus manual lenses? I have all these great Nikon and Zeiss lenses from the old days and I have been using adapters, but with my eyes not being what they used to be, it is getting harder to achieve perfect focus, esp. for f/1.4 lenses I did install the Canon precision focusing screen and while it helps, it still isnot fast enough to achieve perfect focus. Tne Brightscreen sounds like the solution.
Are there any known or experienced issues with these?
