Focusing Screen Type M

[pakodominguez]

Hello,

Does the FDA-FM1AM (type M focusing screen) really works for manual focus?

Thanks for your help

In the Dynax 7D, an M-type focusing screen really makes a difference---for the better. In particular the depth-of-field preview is more accurate. Of course, at slow lens speeds the viewfinder becomes darker than with a G-type screen but that's no problem really. An SR-T camera's screen used to be darker still.

I haven't tried the Sony M-type screens yet but I'd guess they're just the same as the Konica-Minolta ones used to be. For the A900, I opted for the L-type screen, i. e. grid lines. It's a shame that Sony doesn't offer an ML-type screen because that's what I want.

Same here - ML is the obvious technical user choice, combined. I have opted for L because I value it more than M for my normal range of work.

Thanks!
I'm thnking on a M type focusing screen for macro work -I just got 4 Rodenstock lenses (60mm; 75mm; 80mm and 90mm) that I will use on a Minolta Bellows modified for A-mount and sharpness with the regular focusing screen is hard!

In this case I am afraid an M-type screen won't make much of a difference, besides a darker viewfinder image. The M-type screen is most useful at wide apertures, i. e. 1:2.8 and wider. With slow lenses on a bellows which reduces effective apertures even more, I guess you'll be better off with the standard G-type screen.

One more time, thank you for your help, Olaf.
