Richard, my memory will not allow retrieval of all the
lenses I tested, but the following are some that I still
have, the others were either disposed of or returned to
their owners. The El-Nikkor 50mm 1;2.8, Schneider Componon
1:5.6/80mm (used for slide copying) Comparon1:4.5/50mm,
E.Rokkor 1:4.5/50mm.
Your comment on field angle is interesting. I had a friend
who collected enlarging lenses like some women collect
jewelry, he was amazed at the results I got from a
Mayer-Optik Lydith 3.5/30mm camera lens. Being a wide
angle it was marvelous for large prints. In my earlier
years I used a Zeiss Biotar that came with my camera that
was also excellent as an enlarging lens. The Russian copy
of the Biotar, for the Zenith camera would also be worth a
try.
The first El-Nikkor I bought was rejected and I was a bit
put off, but felt obliged to try again; in the event the
second turned out to be an excellent lens. The most
disappointing was the illustrious name referred to in my
earlier post, it was not all sweetness and Leitz! I can
only repeat, f8 is a great leveler.

Thanks Clifford. Well, you confirmed my suspicion that
modern lenses are still subject to the same sort of
manufacturing variations that have always plagued the ilk.
The Comparon was Schneider's economy lens, not to be
confused with the Componon. I have an Enlarging Rokkor, its
an excellent lens, I think a Heliar type similar to the
Kodak Enlarging Ektar. I am a but surprized by the
performance of the Biotar since fast lenses tend to be more
critical of distance than slower ones. The same for wide
angle lenses. One problem with WA enlarging lenses is light
fall off. I have a 135mm Componon I use for 4x5 and have to
burn corners. If I could I would use the next longer lens
for each size, i.e., 75mm for 35mm negatives, 105mm for
Rollei negs, and 205mm for 4x5. That takes a long projection
throw.
