Early SLRs had dim focussing screens, late SLRs had brighter but smaller focussing screens and once AF hit the market they were next to useless for actually focussing (manually that is). There's a sort of historical high spot for nicely built useable SLRs that roughly corresponds with "late 70s".
Not al early SLRs had dim focusing screensl. I have yet to find any SLR, or DSLR viewfinder that is brighter than the one in my 1959 Zeiss Ikon Contarex, though the mult-coated viewfinder in the LX does come very, very close. Of course the Contarex is not exactly compact since it even makes a Nikon look small. 🙂
