[rollei_list] Veiling Flare

Thank you Les and thank you Emmanuel for your welcoming me to the
RUG.

During the decades when a Rolleiflex Standard 622 was my main camera,
I was always delighted with the way it would produce with ease a size
of print that would be a struggle for 35mm.  On the other hand, when
shooting contre jour, which I like to do, with the uncoated Carl
Zeiss Jena Tessar, there really was quite a lot of veiling flare
in the negatives.

So I went over to the dark side and bought a Nikon.  Using a Rollei
had given me buildqualititis and most 35mm SLRs seemed to me to be
made of sandwich boxes, but the F3/T was acceptably robust.  1980s
Nikkor lenses with "Nikon Integrated Coating" (which used, so I've
been told, coating technology licensed from Carl Zeiss and from
Asahi Optical) tamed the flare.

When I got the test negatives back from my "new" 3.5F Whiteface, my
chortle of delight came to an end.  On one frame the shutter had
failed to open; the taking lens had consistently focused closer than
the viewing lens; there was some fogging of the spaces between the
frames; and the frame spacing was erratic.  Only teething problems,
to be sure, and someone less demanding might have asked for them to
be repaired under warranty, but there were too many teething problems
for me so I took the camera back for a refund.

The reason for this saga is that the contre-jour negatives also
showed a certain amount of veiling flare.  Nothing like the amount
I would get from the uncoated 1930s Tessar, but more than I'd expect
from multicoated 1980s Nikkors.  When I resume my search for a 3.5F
Whiteface, and I shall, am I the sort of person who would be better
served by the multicoated Planar rather than the single-coated
Xenotar?  Or am I being confused by the teething problems with a
particular camera?

Later,

Dr Owl
