May 2023 Part 1 — This Month Through Your Adapted Lens

Alan WF

Member
An invitation to dust off your precious (or not so precious) glass and head out to make some photographs: the real reason for the existence of all our lenses.

Here are the guidelines:
  • Images with a removable adapter between lens and camera
  • Images with the lens mount permanently modified to fit a different camera
  • Images with the lens held by hand without an adapter (freelensing)
  • Including metadata (camera, lens, aperture, shutter speed) is encouraged but not required.
  • Comments are encouraged, but please keep them friendly and constructive.
Continued from the April 2023 Part 1 thread.

Regards,

Alan
 
For birders, one of the delights of travel is that common birds elsewhere are often new and interesting to the visitor. A week ago, I was birding in Mexico City with a visiting Canadian, and he was fascinated by the Great-tailed Grackles, which I see every day. This week gone, it was my turn. I was visiting Mérida, Yucatán, for work, and managed to catch some quick birding sessions in the city before breakfast. I found these White-winged Doves to be quite beautiful, despite them being one of the commonest birds in the city.

Regards,

Alan

This lens is rare to begin with- a 5-element Schneider Xenar fully coated, made in the 1940s- as per the serial number. Did not know it was a 5 element lens until opening it up to clean. This is a classic Tessar formula lens where the first element is split into 2 elements of lesser strength. The original 5cm F2.8 Tessars were poor performers used wide-open, edges suffered. Schneider "resolved" the problem using two elements where Zeiss used a single, much thicker element.

Wide-Open, and at F4. 19th century Graveyard in our neighborhood.

SO- a rare lens, probably the only one in Leica Mount.
 
This is one of the first fully-coated lenses ever made, a Carl Zeiss Jena 5cm F1.5 Sonnar. The vacuum deposition equipment was installed around 1935. I have this lens, and another within 100 of it that is uncoated. When bought off Ebay, had a big buildup of internal Haze. Time and effort to carefully disassembly and clean the lens, the inner surfaces were hard-coated. Later lenses, ~1939, used a soft coating on the inner surfaces. A friend of mine in Germany looked up the records and found that another lens from this batch of 1000 lenses, SN 1909598, was also coated.

Converted to Leica Mount, conversion is reversible. Wide-Open on the M9.

A neotropic cormorant resting on one of the old concrete piles in Lago Huetzalin in Xochimilco, México.

Sometimes you just need to get closer, even if it means wandering out on some of the moored boats (trajineras, to be precise). I’m not sure my green clothes worked as camouflage against the yellow, red, and blue woodwork, but the cormorant didn’t seem to be bothered.

The set-up shot is by a fellow birder, Gerardo Cárdenas.
