Now if you were planning on doing video with the Zeiss or older lenses that would be different. I think I would like to use a screen then.
It would be cheaper just to get another AT-1 I bet.
this would be pointless with video because the center of the split screen is used for focus, which means that the subject you are trying to focus on would always need to be in the center.
but why do you mention the pixel LCD screen in terms of focusing? are you using live view to shoot?
