Subject: [rollei_list] OT: Schneider enlarger lenses
Hello all,
I just bought an old Durst 606 enlarger from an even older
gentleman. It came with two Scneider-Kreuznach lenses a
4.5 50 and a 4.5 75. These seem to be in excellent
condition. This is the same company that made the S-Xenar
for my Rollei 35 (I assume). Are these enlarger lenses
valuable, and they don't seem to be coated - am I correct
in thinking that enlarger lenses don't get coated?
Thanks,
Elias
Schneider made some excellent enlarging lenses after
about 1946. These are the Componon series. Schneider also
made some decent economy enlarging lenses under the name
componar. All of these are coated.
Enlarging lenses need to be coated just as camera
lenses do. The effect of flare is a bit different in
enlarging (from a negative) because it causes the shadows to
spread out. A high flare enlarging lens can result in
somewhat muddy looking prints.
As with any lens the condition of the glass is
paramount, look for scratches, gouges, etc. A lot of very
fine scratches, sometimes called "cleaning marks" can cause
a considerable amount of diffusion ruining the contrast of
the lens.
Schneider has posted a complete serial number list on
its web site so its possible to date any Schneider lens to
within a year or so.
