Are the new rolleis really better?

Modern Photography, May 1956, pg. 50-132
Are the new Rolleis Really Better?
(3.5G [E] and 75mm f/3.5 Xenotar)

“Five or four element lens?”

“Now lets take a look at that five element f/3.5 lens. It’s no secret that
there was a cry from professional photographers for a Rolleiflex with an
f/2.8 lens and that these camera enthusiasts only got what they wanted when
a five element optical system was developed.”
“With a maximum f/3.5 aperture in 75mm focal lengths, the story has been
quite different. The four element Zeiss Tessar and Schneider Xenar 75mm
f/3.5 lenses have long been standards of excellence for Rolleis and many
other cameras. What more can the new Xenotar five element offer? For all
but the most persnickety professional, a good Xenar or Tessar will do
nicely. Testing the new Xenotar against a good example of a Schneider
Xenar, the resulting picture definition with both lenses was almost
identical. This is not to disparage the new Xenotar but rather point out
that a good four element Xenar or Tessar can be a very good lens indeed.
Perhaps the Xenotar proved a shade sharper in the corners at full aperture
than the Xenar. However, in actual photographic practice we doubt that this
difference would be perceptible. Xenar or Xenotar? They’re both fine

Rolleinar 2 Bay I Instruction Manual

Just got a fresh new Rolleinar 2 in its original leather case and box. the manual is like new. I scanned a copy and share with all of you in case you might be confused of how to use rolleinar 🙂


Feel free to share or press or do anything with this post 🙂

for use: first attache teh thin rolleinar to the taking lens (then, if required, other optical accessories in the follwing order: Rolleisoft, Filter, Lens Hood. ) Finally, attach the Heidosmat Rolleinar to the viewing lens Heidosmat, red dot up. To install: insert the rolleinar into the inner bayanet mount of the lens and turn to the right until it clicks into position.


Focusing is accomplished as suual on the focusing screen. Rolleinars require no increase of exposure. The depth-of-field always being rather limited at close range, the use of smaller diaphragm openings is recommended
