645Z Split Prism Focusing Screen

Dear All

Am trying to find some good old focusing aids for the 645Z - I find that focus confirmation even on the 55 2.8 is not "pixel-level" accurate. I like manual glass, especially given the price

I have done some research and it seems that the 645D can take the old AA-82 and AB-82 screens - presumably 645Z uses the same screens?

Also it appears that it is no longer easy to find these screens, and brightscreen looks as though it has closed down - anyone has any idea where screens could still be found?

Yup, the 645Z takes the same screens so you should be good to go as long as you can find them.

BTW, the best method for focusing manually with high accuracy is to use live view magnification along with focus peaking. This trumps focusing screens in my opinion.
