(Nippon Kogaku K.K.) RF
Nikkor-T.C
1:5.0 f=50cm(500mm
f/5.0) telephoto lens for Nikon Bayonet S-Mount Rangefinder cameras Year Introduced: 195x#; Discontinued: probably
in 1961/2
#
Stated
date of release of this version in Nikon Rangefinder Magazine as 1955. This was supported
by R. Rotoloni's An illustrated History of Nikon RF cameras which has given a more
precise date as February, 1955; however, Mr. P.Braczho's Nikon Hand Book has suggested
as early as Sept. 1952 with the Preset version introduced in 1954. No info on the
exact date of release for the Leica SM (LSM) version.
For quite some time, no one knows if ever a Nikkor-T 500mm f/5.0 super-telephoto
lens was delivered in a manual mount but I would think there are probably two versions
being produced back in those rangefinder days. However, one thing is for sure, a
version has a preset diaphragm mechanism version. In between, Nikon also had produced
an alternate Leica SM mount (M39) model for other camera brands. Next, the M39 Screw
Mount version has no preset diaphragm installed onto. Whether the same manual diaphragm
for the LSM has been used as Nikon own early version has not been confirmed previously
but as the M39 Leica SM version has a very different look from pictures shown in
most publications and/or literature (see below for a series of the LSM version by
Kelvin LI) . So, personally, I would think such possibility strongly exist. Next,
please take note that Nikon had also introduced a fixed aperture F-mount Reflex-Nikkor
500mm f/5.0 Mirror lens in 1961
and SHOULD
NOT
be mixing up with this variable-aperture telephoto lens. i.e. The Mirror-Nikkor has
only a fixed f/5.0 aperture. Controlling aperture of that Mirror lens is via use
Neutral Density Filters or alternating film speed/types. Partly this was one of the
main reason why the rangefinder S-mount model was so low in production figure with
the debut of the F-mount Reflex Mirror Nikkor lens. |

NOTE:- Recently,
with a stroke of luck, Kelvin
LI,
a long time active Ebayer who specializes in collectible cameras had presented a
rare LSM Nikkor-T 50cm f/5.0 in his collectible auction. With permission, I am compiling
the said lens here for all Nikon enthusiasts to share the thought I felt earlier.
This lens has a S/N 647099

The Nikkor-T.C
50cm f/5.0 LSM
version
has a few areas which are quite different from the models that has the Nikon's own
Preset Diaphragm Mechanism installed. I wouldn't think Nikon will specifically released
a version with a different design in Leica SM i.e. assuming just like what Nikon
did for the Nikkor-Q 25cm in M39 SM which wasn't supplied with the preset mechanism,
but you can compare the lens tube section and even the wooden box that was supplied
with the lens (as standard accessory) where they are so different from version in
Nikon S-mount that followed (See below for another view of a version with Preset
diaphragm control). Another point of interest is:- I do notice from the few photos
that I gathered over the years on the Nikkor-T 50cm lens (as well as pictures used
in the respective publications from the few Guru collectors such as R.Rotoloni and
P.Brackzo etc. ) that virtually all of them were coated as indicated from the lens
data as Nikkor-T.C 1:5 f=50cm.
The on-lens f/5.0 maximum aperture can be considered as moderately fast in enabling
available light photography. And when combining it with a faster ASA film type, it
may provide good shutter speed options to prevent possible action blur which can
be quite common in super-telephotography. By the way, this lens was also one of the
only few Nikkor lenses that ever provided with a small f/45
minimum aperture (It provides a useful DOF scales referencess: f/45, f/22, f/16 and
f/8.0). By combining this extended level of depth of field control options and its
strong perspective compression optical characteristic, all these elements may be
useful for certain kind of creative and/or special application photography. |

| This is a very
huge and heavy lens. As you can see a typical setup from the illustrative photo below
with the customary combination in a RF Nikon body, Reflex Housing (shown is a Model
2
Unit) where even the dedicated lens hood is an extra-long type. Neither the weight
factor at approx. 8.5kg would suggest this is a very friendly lens to hang aorund
with. A very steady and rigid tripod is a MUST and Nikon had the tripod socket also
in a extended scale in diameter. You can literally forget about handheld shooting
unless you have special interest in "blur and movement" photography...
Some Japanese Nikon collectors had suggested (as well as R.Rotoloni) total production
is less than 300 units. I think it has both a lot to do with the price tag it came
along as well as finding good, vast application for this extremely rare piece of
Nikkor super telephoto lens. Today, even after half a century, the scenario also
remains the same - except for small group of Nikon collectors / researchers / camera
historian who may be specifically wish to re-building up a complete lens library
of the glorious old days of Nikon rangefinder system. |
