instantphoto.eu MANUAL LOMO INSTANT WIDE or LOMOWIDESTAX
The Lomo'Instant Wide camera partially
fills a gap that Fuji didn't want close. Fuji makes wonderful instant
film that could be professionally used, but only makes crappy cameras
with very limited specifications. It has many features that Instax
cameras do not have, a page for this camera is here.
body of this camera is very compact, the ejection is quiet and
reliable, much better than the manual Lomo Belair Instant back with its handle. As there are no
motorized Instant Wide backs available (several projects have failed),
I tried to make a full manual camera out of a Lomo'Instant Wide camera. This is a step to step description of my project.
starts with dismantling the Lomo Wide. All first steps are reversible.
This might also serve as a guide for shutter/aperture repair of
the Lomo'Instant Wide. I will indicate the point of no return.
First unscrew the three screws at the deepest
point to remove the shutter/optical assembly. Be careful with the
Next remove the rear lens (3 screws clearly visible), you are now at
the diaphragm, a simple plastic blade, moved by an electromagnet for F22, otherwise it is F8.
you remove the other screws still visible, you will reach the shutter. Two plastic blades, managed by another electromagnet.

far so good, it would be reversible. Emptied of all moving parts,
the Lomo block does not produce any error, if you push the shutter button, it
ejects. The principle is simple: if there is a lot of light, the
diaphragm magnet will have current to put the blade with the small hole in
place. The shutter opening time is managed by second magnet, current=open, no current=closed.
question that arises: if you cut the
cables, will it produce an error? You need an intact circuit to eject.
I didn't see any other wires than those for the magnets. This is the
point of no return. If you cut the cables, it's over. I have done it, I
cut the cables finally. I presumed that Lomo does it the simple way,
they won't complicate their lifes. So: 2 magnets, 4 wires and no
electronic control. I cut the wires and all still worked.
This is the body with all shutter and optic parts removed, cables cut and the inner tube sawed off.
Now you can attack the next step: fix the new optics at the right distance. It won't be that easy, but we'll see...
shutter/optical block comes from a camera of my collection, an
Ensign 820. It has front cell focussing, so no helicoid necessary. It's
said to cover 4x5. Before taking the optical block off the camera,
measure carefully the distance from the lens to the film plane and
write it down.
The new block fresh from service.
took an old theaded aluminium extension tube which just fitted aroud
the outer tube of the Lomo body. The optical block is fixed via step-up
rings to the thread of the tube. Taking measuresI found out that it is
2mm too long. A ground glass confirms: it focusses up to 15m, but not
You can easily make a ground glass yourself. Take
an empty Fuji Wide cartridge and cut the back part off so that there is
a frame left. Make a ground glass from clear plastic, e.g. a CD
cartridge cover. Cut the clear plastic to the size of the cartridge.
Take some medium grain sandpaper and sand one surface until it
resembles a ground glass. Put it into the cartrigde frame, sanded side
down. Eventually fix with some glue. If you put the frame into your
camera, you can control focussing. In this case I took 2 mm off the
tube and focus was fine.
Some what longer than the original, but not too long.

disappointment the next morning, it doesn't work. There's a lot of
vignetting and there is a bright patch in the center of the photos.

need a bigger tube and cut into the heart of the device to avoid
vignetting, that's possible. Maybe there would be no problem with a
wider lens, like the original Lomo lens. But the optics have a problem
tried the optics on the old Ensign camera on 120 film and it was good.
Optics, aperture and shutter were revised by a pro. There is something
that escapes me. I had
exactly the same phenomenon with a camera that option8 made for me,
which he kindly took back and made me a different one, it is
a pity. One can see that there could have much sharper images than with
the Lomo optics. So I gave the camera to a friend, a professional of
camera work, to get vignetting out of the way. He cut a bigger hole for
a bigger basis..

Photo inside, F11, 3m. No vignettig and maybe only a hint of the clear patch.
Photo outside, F22, infinity. No vignetting, a bit of the clear patch still visible.
you have any ideas about the clear patch, please let me know. I tried
filters and hoods. I will try another lens later and I will try ND
filters to get speeds and aperture down. That's it so far.
