Camera Co., Ltd.
| Kanto Camera Service
specializes in camera repair service in Japan.
We have been in business since 1970 and we
have over 40 years experience in this field.
・Attitude toward Repair Service
Basically, we give priority to restoration
of function. We repair cameras to be able
to take pictures. For that, we use genuine
parts as much as possible. However most of
the spare parts for vintage cameras are no
longer available. Then, we occasionally use
spare parts produced by our company. This
is because we think it will be meaningless
if you cannot take pictures although respecting
・About our Overhaul
The contents of OVERHAUL can vary from shop
to shop. Many repair shops take a cover off
and lubricate, do some simple adjustment,
and say overhaul is done. But, our overhaul
is completely different. We start overhaul
from disassembling the camera. Next, we clean
every parts and exchange grease. Finally we
adjust each mechanism, and assemble the camera.
After quality check, our overhaul is finish.
Even if customers cannot see the inside of
a camera, we never cut corners on the maintenance
of cameras. We believe that good maintenance
keeps a camera in a good condition for the
Our baking paint has been developed especially
for painting camera. After painting part,
we bake it in a special oven, so we can get
the paint durable and also beautiful finish.
The most important thing for beautiful paint
finish is the pretreatment process. If you
use sandpaper to strip metallic coating, the
base metal will be scraped. If the base metal
become thin, the cold and heavy feeling of
the metal may be gone, and its texture might
become lighter and cheap. Of course, our method
is different, and it hardly cause a damage
to the base metal. Furthermore, our skilled
craftsmen prepare the surface with careful
base repair works and sandblast (the actual
material is glass-beads-sand which is smaller
than sand). Since we invest a good deal of
time and effort to the pretreatment process
like this, we can keep the beautiful finish.
・Lens Polishing and Coating
We can offer lens polishing and coating. For
example, when your lens got haze and could
not be wiped off, we can remove the haze by
polishing, and at the same time we can recoat
the lens. However, polishing is not the best
method at every case. If the lens was polished
a little too much in order to remove the haze
and the scratches, the lens performance would
get remarkably worse. The center of the picture
(as long as it is in focus) may be relatively-OK
, but the depiction at the edges will be worse.
We often find lenses which has been polished
too much with the purpose of only making the
surface clean are on the secondhand market.
As you might expect, we never do such polishing.
Because there are these kinds of problems,
polishing is recommended in the case of bad
condition that affects photo. Please think
that it should be done for the purpose of
making the optics a bit better than current
worse condition. Some of the old lenses tend
to get haze or deteriorate with age. For those
lenses, we have produced alternative lenses
for replacement. With replacing the lens,
you can get not only good depiction but also
good appearance. Those alternative lenses
have been regarded as equivalent to the original
lenses of a good condition by the resolution
test, the MTF measuring test, and the test
photography of professional photographer.
We offer single lens coating. Since the color
of the coat differs according to the coating
thickness, we adjust color and thickness to
be the same as the original coat. The vacuum
deposition equipment is usually put into operation
to coat many lenses at the same time, so you
can not adjust the coating thickness and color
one-by-one. But, we do one-by-one without
thought of profit.
When you repair a lens, you need to disassemble
optical lenses, moreover you need to take a helicoid
and a mount off, and finally you assemble it all
again. All of those work cause to the change of
the depiction of the lens. If it is within an allowance,
there is no problem, but sometimes it may be beyond
the permissible range. In that case, only checking
and adjusting of the infinity focus is not enough
to notice the change of the depiction, then repair
work may complete without fixing it. To prevent
this kind of problem, you need to assemble the lens
with measuring the resolution and contrast. In our
company, we assemble lenses with measuring the resolution
using the projection chart in a dark room, and measuring
the contrast with MTF measuring equipment. Without
those procedures, assembly seems like a repair by
speculating. We never do such a half-hearted repair.
We have high skill and a lot of experiences of modifications.
For example, viewfinder of the Leica M6/M6TTL has
a halation problem, and we developed the modification
to reduce the halation. Later, Leica Camera AG started
to provide the modification of reducing halation
with a different way in Japan, but we still think
our modification method is more efficient. Other
modification is taking the sound of governor off
at 1/250 from Leica R6.2. We also developed the
way of making the Olympus Pen F series' viewfinder
brighter and making Nikon F3 AE lock operate by
pressing shutter button halfway. We provide a variety
of modifications. Please check them out at our website.
・Mercury Battery Adapters
The mercury batteries such as MR-9 are no longer
available, and there are no alternative batteries.
To solve this battery problem, we produce and sell
battery adapters which you can use with silver oxide
battery. Our MR-9 battery adapter change the outer
shape and also reduce the voltage of SR43 (silver
battery) to about 1.35V.
We are selling cameras, lenses, and accessories
in a unique style of Repair Company. Secondhand
cameras and lenses that have been checked, repaired,
or overhauled by us are available. And accessories
we developed are also available.
・Diploma of Leica Camera AG
We have some craftsmen who have trained in Leica
Camera AG. They have Leica diploma and have acquired
the skills of Leica Camera genuine repair method.
