My first SLR was a Practica LTL 3.
I miss the FF. I miss the ability to manually focus.
I do not miss the quality of the lenses though

That's 3 stops?
I can't imagine a focusing screen making that drastic of difference in exposure.
I can't say I noticed a difference on my XK when I changed the screen, which I did frequently.
I need to look into this, I was thinking of getting a split-prism.
Nowadays, in Canon DSLRs the light meter is in the prism housing.
There used to be camera's with the light meter in the body (below the focussing screen). I those cases changing the focussing screen didn't matter.
Also off course, back in those days, not a lot of camera's offered anything apart from some sort of CWA type metering pattern, so it didn't matter much.
