Komura f=80mm 1:1.8 for Nikon-S (RF)
KOMURA was the brand name of a series of interchangeble lenses made
by the Sankyo Optical Works Inc. (Sankyō Kōki), established in 1954
and kept in business to the beginning of the 1980's. Its president
was Mr. Mitsuru Kojima.
f=80mm 1:1.8 "Long Focus Lens" - notice, they don't call it Telephoto
on the lens case.
Why? It's an classical ERNOSTAR design, which is different from a
Telephoto.
It's longer in size than the SONNAR-design Nikkor f=85mm 1:2
(Sonnars always are short in length) and slightly faster. Available
in different mounts: Nikon Rangefinder (Black/Silver "Zebra" style,
Leica LTM/M39 (Black/silver), M42 SLR and
Exakta-SLR. All are quite rare.
According to Takehiko Kobayashi (Lenses for Leica, LHSA-article) it
was released in 8/1957, which date matches the "Zebra" or "Black"
style fashion.
Now, look at the coatings. Nikkor-P.C. 1:2 f=8.5cm, Komura f=80mm
1:1.8, Canon (Leica LTM) 85mm 1:1.8.
The Canon (released latest, 1962) and the Nikkor have much deeper
coatings than the Komura, which blueish coating looks like 1950'
style. So you may believe, it flares more than the others.
Recorded Serial Numbers:
4550123 my/ bought in 2009, sold it about 2015.
4550186 photo arsenal
4550207 photo arsenal
3550238 Kevins cameras
3550096 Ebay 231,38 USD M42
3550275 MFForum, M42
Total produced: despite the "high" serial numbers, some hundred in
each mount, maybe 1000 in total (at best)
In direct comparison, the Komura isn't just as "silky-smooth" in
handling, surface quality and lettering than the Nikon lens. But it
wasn't that expensive too, back then.
Lens design: 5 Elements in 4 groups - a perfect Ernostar! Greetings from
Dr. Ludwig Bertele.
The
following is UNDER CONSTRUCTION!
Komura f=85mm 1:1.4 for Nikon-F (SLR)/
native Nikon mount
The fastest 85mm for Nikon or any SLRs in 1964, and
for the next 10 years, until Zeiss released their PLANAR 85/1.4 in
QBM mount. Carl Zeiss Jena had the Biotar 75/1.5, but made it mainly
only in Exakta mount (some M42).
Design similar to the "Dream lens" CANON RF 0.95/50mm
Komura f=100mm 1:1.8 for M42 (SLR)/ Uniadapter
According to this site the Unidapter lenses were
developed in the 1970's.
Difference in coating: 100/1.8 is blueish, while 105/2.0 is
amber/yellow-brown.
