On a few old 35mm cameras I think I recall that depending on the lens I used, the focusing aids (split image rangefinder and microprisms) changed a bit.
I now own a couple of Tni DSLRs (both with kit lenses) and I miss my focusing aids even if I rarely focus manually anymore. But I don't know if the lack of focusing aids is because I own inexpensive bodies or because I own inexpensive lenses.
Are split image rangefinder and microprisms part of the lens or the body in modern DSLR systems?
