- Although I really hate the viewfinder, I've left it intact for the time
being. I would like to replace the big viewing lens with a ground glass,
then add a prism to the top, like the 45 degree prism the Russians made for
their Hasselblad copy, the Kiev.
- On my version, I've installed a flash shoe on the top plate. This was
salvaged from an old folder and attached to my top plate with screws. I use
a Sunpak Auto Zoom 2400 with several tilt positions. Placement of the shoe
will depend on the type of flash you use.
The Russian Sputnik stereo camera is the only medium format stereo camera that
was mass produced after 1960, and surely the easiest to find. Its reasonable
price on the collectors' market has helped bring many into the field of MF
stereo. Unfortunately, it is a camera of many design faults. The most serious
are light leaks, internal reflections and lens flare. Once these problems are
eliminated or at least reduced, the Sputnik is capable of producing excellent
results. This guide gives you my suggestions only, as there may be other ways of
improving performance as well. Some of the modifications are reversible, an
advantage should you decide later you would rather return your Sputnik to its
original state. While far from definitive, these suggestions may prove useful
for those who have despaired over the poor quality of their Sputnik images.
HERE'S A BRIEF LIST OF RECOMMENDED MODIFICATIONS:
- Reducing Internal Reflections
- Reducing Light Leaks
- Reducing Lens Flare
- Adding Lens Shades
- Improving Advance Performance
- Adding Strap Lugs
- Adding a Tripod Screw Adapter
- Adding a Flash Shoe
- General Cleaning of Optics and Relubricating Focus
PLEASE NOTE: As Sputniks differ from body to body, all dimensions here
are approximations only. Please measure your own camera carefully before making
baffles or plates.
Probably the silliest of design concepts was having a shiny surface to the
inner chambers of the Sputnik. Light reflects off the sides and fogs the
image, thereby greatly reducing contrast. There are two ways to reduce
this: flocked paper and baffles.
Flocked paper is a fuzzy black material that looks like very fine
velvet. It is available from Edmund
Scientific Co. at a very reasonable price. To line the inside, cut out
separate pieces for each of the sides as well as top and bottom of the
film chambers. Making a paper template first would be helpful. When they
fit, glue them in place with contact cement.
|Baffling involves making walls inside the chambers to block the
reflections. These can be made of cardboard, brass or aluminum. Mine were
K&S #255 aluminum .016 thick. These were 53x55mm frame with 33x40
square openings. A 5mm bent strip along the edges was also needed for
securing. This was painted and placed to butt up to the edges of the spool
well. A slight bend on the top was needed to accommodate the mirror well.
Next, I made a second set of baffles to go closer to the film plane. For
these I used K&S #173 3/16" angled brass. This is a strip of
brass with a 90 degree bend across its width, perfect baffling material. I
cut and bent it into a couple of squares 57x53mm, painted them matt black,
and stuck them inside 16mm from the film plane. All baffles were secured
with contact cement.
My first suggestion is to paint all shiny or metallic surfaces inside or around
the doors with flat black enamel, especially the inside parts of the back lock.
Next line the space between the doors with a strip of black velveteen using
contact cement. Velveteen can also be used as a baffle around the inside hinge
area. Attach strips on the inside door where the hinge meets. Attaching some
thin black string, like crochet wool, to the inside grooves may be effective as
long as there is room. If the above method doesn't work, more drastic measures
may be needed.
|One method is a camera bra. It has a similar function to the camera
case, but it's more light tight. Using 1/8" matt board from a framer
or art supplier, cut four pieces to cover the bottom, back, and sides.
Leave about 1/8" each dimension, and leave an extra 1/8" width
for the sides and bottom. Cut a hole for the film counter, measuring from
the top of the board. Also cut a hole for the tripod socket, measuring
from the front. Now tape these together with duct tape. It should fit
loosely from the bottom and back. Now cut two pieces 2 1/2"x 3",
and glue these vertically to the inside of the back, one butted up to each
side. This gives a little groove for the door lock. Now cut 1/2" wide
strips of matt board for the side, tops, and back. Cover the inside with
black velveteen,and the outside with vinyl. A piece of vinyl attached to
the front top corners of the sides will secure the front. You could even
add latches for a strap.
||The most effect option is to make a brass or aluminum plate that
completely covers the top and bottom of the body. The top piece will be
c-shaped to allow for the viewfinder, with holes for the knobs. If you
drill holes in the top plate to allow for the six screws that attach the
knob assemblies, you can simply attach the top plate with those screws
without having to glue. This will cause the film posts that fit into your
spools to not fit all the way down into the spools, so some modification
would have to be done to the knob assemblies. You may also want to make
little protrusions to hold the lug straps, especially if you don't use a
case. The bottom will have a hole for the tripod mount. Attach velveteen
around the door edges of the plates, then glue the base to the bottom
using contact cement. The advantage to this method is that it allows you
to include lugs for your camera strap as well as a flash shoe.
Reducing lens flare
Loosen the tiny set screws around the lens mount (three to a lens) Just loosen
them enough to remove, or you'll lose them ! Pull off these covers. You'll see a
ring clip holding the middle element in place. Carefully remove these clips with
a dental tool or small screwdriver. Don't let it spring! Hold a tissue over the
front of the camera and face the camera down. The middle elements should drop
out. These are the ones that desperately need the edges coated. A good quality
permanent black marker should work. Cover the edges as well as the etched bevel
that forms a 45 degree ring around the optic. After they have completely dried,
dust off and replace. You may want to do further dusting with a dust gun as well
as clean the other optics while you are in there.
These are definitely a must. Some Sputniks did have them, but if yours doesn't,
try the following:
- 27mm series V adapters with series V shades. These are sometimes found in
used camera stores for a few dollars. The adapters slip over the lens
mounts, then the shades screw into the adapters.
- Another ingenious way I've stolen from Stan White. Take two caps from
Ilford Multigrade Paper Developer and cut the appropriate holes in the
middle. The screw threads even act as light baffles!
Another common problem is a sticky advance knob. It can bind and be very hard on
the fingers. Removing the advance knob and assembly, cleaning off the old
lubricants and replacing them with a little vaseline or a proper non-migrating
lubricant will help performance a little. The next option is to replace the
original knob with a bigger one. Removing the tension spring will reduce
friction, but you would have to instal a ratchet gear inside to prevent film
Cosmetic and Other Modifications
- Since I'd done so many modifications, I decided to also give it a
Mod look. I used a textured splatter paint to liven up an incredibly
- The shutter trigger is too small and hard to find. Other than
attaching a new trigger mechanism to the side, you could try using an
accessory release that screws into the cable release socket. These
should be available at used camera stores.
- The tripod screw mount needs a 1/4" insert to use with standard
tripods. These should be avialable through most camera dealers.
- Although I really hate the viewfinder, I've left it intact for the
time being. I would like to replace the big viewing lens with a ground
glass, then add a prism to the top, like the 45 degree prism the
Russians made for their Hasselblad copy, the Kiev.
- On my version, I've installed a flash shoe on the top plate. This
was salvaged from an old folder and attached to my top plate with
screws. I use a Sunpak Auto Zoom 2400 with several tilt positions.
Placement of the shoe will depend on the type of flash you use.
General Clean and Lube
Lens cleaning is pretty straight forward, just be sure you use the appropriate
lens cleaner and tissue. Focus lubricants must first be removed with a
distillate like naptha, then replaced with a non-migrating lubricant.
