On the subject of older lenses, I'm off to the darkroom (oh joy&#33 to see how a 1934 Voigtländer Heliar fares when enlarging a 9x12cm to 8x10"...

I already know what 1960s Xenars, APO-Lanthars, Symmars and Angulons can do, as well as my newest lens: 1972 121mm Super-Angulon.

So far, I see no need to "upgrade" my lenses.
