we will be discussed some of the alternate versions designed for LEICA SM and Contax-mount
for this Nikkor-P 1:2 f=8.5cm telephoto lens. Briefly:- with a little hands from
Mr. David Douglas Duncan, Time Magazine photo
journalist who had been commisioned to cover the Korean War when it broke out in
June, 1950 he was experiementing and tried out for the first time with the Japanese
optic on his Leica, the resulting works had been published in many journals and newspaper.
It started a wave of cusrious minded reviewers and other photograpehrs with this
relatively unknown Company in the occupied Japanese terriroty. That was how Nikon
and Nikkor was exposed to the Western media. | RELATED STORY |
can provide us with a rough idea when actually Nikon began to enjoy its popularity.
Prior to this, to the western consumers/photographers they were still largely remained
as a replica-maker which offered affordable alternatives of German brands. The series
of mistakes made on the Nikon 1 and followed up Nikon M was also part of the reason
despite NIkon second attempt trying to patch the initial mistake of 32 x 24 with
a wider 34 x 24 film format. Although I can't be conclusive whether Nikon was trying
to create a new film format standard or simply was faced with technicalities. But
since they have along been developing lenses for others (most well known was being
the HANSA CANON), they would be so creative trying to do just that. Anyway, those
are history. In the eyes of the antique Nikon collectors, both the Nikon 1and M were
very collectible as both of these RF Nikon bodies form 2 out of 3 camera models that
provide with an odd format RF Nikon bodies (3rd model was the S3M with built-in capability
of shooting 72 exp. in a 17x 24 format). So, whatever I said will not reducedtheir
premium as used equipment hehe ...
LEICA Screw Mount
(LSM) - Nikkor-P
1:2 f=8.5cm Tokyo ("MIOJ" marked on
lens barrel) S/N
|Shown below is
an unknown LEICA SM Nikkor-P 85/2.0 TOKYO MIOJ version with an interesting production
serial number. The S/N starts with 801xxx which incidentally was found as the earliest
batch among the Bayonet-Nikon model EXCEPT it has an additional number behind in
this LSM version which makes it as a 6-digits model. However, if we assume
Nikon has allocated the 6-digits S/N system for the Leica SM version, the finishing
and overall appearanceappearance of this supposedly earliest LSM model could not
be produced at the same time as the Nikon bayonet version. Reasons being:- Except
for the large lens data inscription, the rest of other engraved numerals and lettering
on lens barrel were more refined which are identical with the version with S/N 903XXX
featured earlier. So, if the assumption was accurate in some ways, the LSM models
could be produced after the initial attempt with Nikon own version.
Whatever it is, this unknown Nikkor-P 85/2.0 TOKYO MIOJ was marked with Serial Number
801250 - only 10 number from the version BELOW - except this waswas made with a LEICA SCREW MOUNT configuration.
As I can't access the 801240 below to verify if it was also has a LEICA screw-mount
at the rear. But if it is, then may be we can establish a new theory that 6 digits 801xxx (Original Nikon
S-mount uses 5
for its earliest batch) could be the earliest batch to differentiate the LEICA SM
version from the Nikon own bayonet mount version.

|Next, due to
the different lens configuration which affect shooting and lens handling property,
the LEICA version has different rotational direction from the Nikon. i.e. RIGHT --->>>
LEFT. Further, unlike the earliest models made for the Nikon bayonet mount models,
it was interesting to note the LEICA SM batch has both distance/DOF scales index
colored, as well as an additional infra index (R) being added (the latter feature
was not available on the earliest Nikon S-mount model)s. The additions could probably
be aiming to improve its lens features with added appeal to LEICA users.

10 digits difference

Tokyo ("MIOJ" marked on
lens barrel) w/ f/16 minimum aperture
take note this Nikkor-P 85/2 Tokyo MIOJ models were similar with the early Nikon
Bayonet mount models with MIOJ marking engraved on lens tube. The minimum aperture
was confined to f/16 only for this version (Late LSM Models has added provisions
for f/32 and /22 - read more info below).
of the Nikkor-P
|While most Nikon
folks are fond in focusing on the Nikkor-P 85/2. Many do not realize Zeiss JENA has
a very good telephoto at this focal length too. I think mainly due to Leica had seemingly
very contented in kept refining their established lens group of 73/90mm focal
length LEITZ lenses* while within the Leize
lens family, Leica only has an excellent Summarex 85/1.5 (1943~1960) (where
Nikon eventually brought their fast lens speed 85mm telephoto Nikkor-S 1:1.5 f=8.5cm
in 1951 to take on the Leitz); and thus, the Zeiss Sonnar 85mm 2.0 was often being
compare to the Nikkor-P as both lenses share similarities in identical focal length/maximum
lens speed. However, I guess there was not a secret where Nikkor-P 85/2 embodies
with a strong flavor of the Zeiss design inside out as during the Nikon RF infancy
stage, German optical designs were often being used as basis for the oriental makers.
So, to be fair, we should also adjust/tune our thinking where it should be other
way round whenever we are doing an accessment of a product appeared at the time of
The adoption of the optical design for the entire product cycle of the Nikkor-P,
despite it has gone through so many changes physically has remained using the same
optical construction of 5 elements in 3 groups design throughout. In this respect,
I would think there is any question in doubting the optical excellence it can deliver
for photographers as this was exactly where Japan overall optical industry were first
being introduced to the West. So, it would be an acknowledgment to find a oriental
made optic was used on a Contax rangefinder cameras.
* RELATIVE:- Velostigmat
Summicron 9cm f/2.0
Summicron 90mm f/2
different designs of the Carl Zeiss 85mm f/2.0 Sonnar appeared in different
stages/mount version. The above is Contax. The left has a LSM configuration.
In general, I would think during the initial stage, Nikon had been carefully accessing
the difering architecture between Leica and Contax as well as other aspect such as
marketing etc. which had them finally settled with Contax/Zeiss framework as the
basis for their Nikkor bayonet lens design for their S-series models. This decision
had probably resulted with some of the share identical lens handling features between
the two Companies in some examples such as rotational direction of the lens from
RIGHT-->>LEFT (Leica operates the other way round i.e. LEFT-->>RIGHT).
Even the major segment in aperture / focusing and lens mounting section but with
an exception of the rear ring portion. Other differences are just the thickness and
dimension of the individual rings. Typically with a Contax Mount Nikkor-P 1:2 f=8.5cm
telephoto lens are quite similar with the Nikon bayonet version.
|There are a few
lens features that separate the Nikon from the Contax-mount models. The MAIN problem is,
I still have NOT come across any of the MIOJ TOKYO Nikkor-P 85/2 in Contax mount
yet which made the issues here a little muddy (unclear) here so, all I can based on is this
"EP" model where presumably was either occupation OR just after but before
the next version upgrade which has a different black/chrome appearance
I have placed this explanation on else where in the Nikkor site. But just to save
you from clicking to other pages just to find out what the hell is this mark stands
for. An "EP" marked item
was just to differentiate mechanize / goods that sold during the post war Japan era.
EP engraved items were distributed via military "duty-free" outlets or
sometimes referred as PX distribution system during the period. Technically, you
can refer them as the same with "MIOJ" (Made in Occupied Japan) products
except EP extends longer period for the US troops in Japan after quoted "MIOJ"
on products were expired.
Case stufy references on some of the Contax-mount models introduced at
First was the
added aperture of f/22 and f/32. It was indicated on the DOF scales as well. This
addition was also being replicated over to the LEICA late Nikkor-P 85/2 models (refer
to the LSM section above this). Another inclusion which was missing in most of the
MIOJ Tokyo edition on Nikon bayonet models is the infra index that also was provided
on the LSM models. However, as the difference in lens handling property, the Contax
models has the index placed at the left after the distance index and it was red colored.
One thing that kept puzzled me was why this was not made as standard feature on the
all chrome MIOJ Tokyo edition on the Nikon mount models.
Lastly, all the models made for Contax has an inscription of a "C"
on the other side of the lens tube. Note: at least one version that had surfaced
that uses without the '
encasing the alphabet "C". It uses different font too (see a few
lines below this).
with S/N 292903 at the right hand side has a different "C" (Contax-mount
Nikkor lens) used on the lens barrel. This was the first model that I encountered
without and open/close inverted comma. Besides, it uses a different type type face.
The usual engraved marking is marked 'C'.
me, the differences can be minute, but all I am interested was during the time of
change, does the Contax models have other changes too ? --->>>
