135compact.com       16mm cartridges

16mm film is a movie film format, as was 35mm film. In the early days it was cut from 35mm film and thus had perforations on one side (single perforation). Please note, that the perfs and their area of 35mm are bigger than those of genuine 16mm film. The 16mm format was rapidly adopted by still camera producers to build smaller devices. The film usualy sits in a cartridge, but no standard has been established, many have 2 cassettes, one feeding and one taking. So every maker invented his own system. Some, like Minolta, even sold a choice of readily available film cassettes. If you want to use your camera, you should at least have one (pair of) cassette(s).

16mm film is still made. There is double perf, single perf and unperforated film. Check, which one suits your camera. Some need perfs to advance. Smaller picture formats can use double perf film, bigger ones would have the perfs (or sprockets) visible in the picture area. There is 10mm of usable space between the perfs of double perf film, 12.5mm to the side of single perf film. Film can also be s(p)lit from other formats like 120. Below the "back" button at the bottom of the page I will show some results from expired film.

Let's start with the Minolta cassette.

An empty Minolta cartridge. It was widely spread and it obviously later inspired Kodak for their 110 cartridges.

It's all plastic, easy to take apart. The take-up spool is quite big as the film is attached to it and wound by fractions of a turn, not via perforations. So the difference in spacing between a nearly empty and a full spool isn't too big.

You can feed any 16mm film for early Minoltas, 10x14mm format. The later ones need single perf, the perfs have to be at the bottom of the cartridge, towards the "bridge" between the 2 spools. Or you feed unperfed film. Feeding film has to be done in total darkness or a good changing bag. Cut about 45 cm (18") of film, roll it tightly, put it into the feeding side, let some cm go out of the slit and close the lid. Secure the lid with some tape. The rest can be done in subdued light. Tape the first cm of film to the take-up spool put it into the take-up side and close with the lid. Secure with tape and you are done.

New Old Stock (NOS) Minolta film. I even got results from the film expired in 1973 and shot in 2019. But it was a bit over the limit, the emausion flakes off in some areas. I developped it with Rodinal 1+25, 9 minutes at 20° (as if it were 80 ISO) and got acceptable results. In any case you get a reloadable cartridge.

The cartridge is protected by a sealed case.

Let's continue with the Kiev cartridge.

jpg/16_kiev_30_IMG_1014.JPG
A Kiev cartridge, obviously inspired by the Minolta cartrigde. The first Kiev Vega was a copy of the Minolta 16. Even the cartridges matched. But with the Vega 2 and all later Kiev cameras, they changed the picture format to 13x17mm, which needs unperforated film, and they changed the core of the take-up spool to get more film into the spool. So a Kiev cartridge cannot be used in a Minolta camera.

jpg/16_kiev_30_IMG_1015.JPG
All plastic, as the Minolta.

jpg/16_kiev_30_IMG_1018.JPG
Taken apart. Loading procedure as for the Minolta.

jpg/16_kiev_30_IMG_1054.JPG
Kiev also sold 16mm pre-cut film, but it's just the film, without cartrige. This one expired in 1993, not usable anymore (see end of the page).

jpg/16_kiev_30_IMG_1055.JPG
Both cartridges compared. You can easily see that the core of the Kiev take-up side is smaller. So a Minolta cartrige fits into a Kiev, but Kiev cartridge doesn't fit into a Minolta. I have been told that you can swap the bigger Minolta capstain with the smaller Kiev capstain. I have not tried it yet as I have cartridges for both.

Mamiya sold film in cartridges as well. As most photo dealers would not take all possible cassettes in stock, they tended to take those that sold best. It seems that Minolta took an advantage over Mamiya, so Mamiya lost the battle about 16mm cartridges and then sold less cameras. In the end they all lost to the new Kodak 110 Pocket cartridge.

Let's first have a look at the Mamiya Single cartridge. These were reloadable. In the beginning of 16mm film most people loaded their cartridges themselves from bulk. You usually got your cartridge back from the lab with your developped film. They look like this:

jpg/16_mamiya_16_cartridge_IMG_4559.JPG
4 Mamiya metal reloadable single cartridges.

All single cartridges fit all cameras. For the take-up side you have to open the cartridge, take out the core and slide the film start under the spring. Then put the core back, close the cartridge and pur both cartridges into the camera. Close, wind twice and you are ready.

As most 16mm camera producers sold ready loaded film for their cameras, Mamiya did the same and created its Mamiya Double cartridge. They are made of plastic, but can be reloaded as well. They look like this:

jpg/16_mamiya_16_cartridge_IMG_4628.JPG
Some old film and an empty cartrige.

The double cartridges fit also into the old models. Eventually you have to change a screw on the bridge between the 2 compartments to a headless one. To reload these cartriges you will have to take the black tape off to seperate them and prepare bits of tape to re-tape them.

Next let's have a look at at the Edixa 16.

jpg/16_edixa_16_IMG_0938.JPG
Edixa sold its own film in cartridges, which were technically like 35mm canisters, film taped to to a core so that is could be re-wound into the canister. The camera has a removable winding spool which you need if you want to use this camera. Size-wise a Minolta or Kiev feeding spool would fit, but you would have to deform the lid to make room for the rewinding mechanism. The camera uses unperfed film. You can use single perf film if the perfs are towards the top of the camera, the camera opens from the bottom and lies on its top in the picture above. I have not seen an Edixa cartridge yet.

Nevertheless you can load and unload the camera in the dark or a changing bag. Put the start of the film into the winding spool, put the spool into place, tightly roll the rest of the film and put it into the feeding side. Close the camera. You can even use the 2 photos before the counter goes to "1". Do not exceed the film numbers as it won't stop at the end. Unload in the dark directly from the winding spool to your developpment reel.

Let's then have a look at the Mec 16 SB camera.

jpg/16_mec_16_sb_IMG_0958.JPG
The Mec has 2 identical cartridges.

jpg/16_mec_16_sb_IMG_0960.JPG
Mec also sold its own film in those cartridges. The camera needs perfs for film transport. It was designed for double perf film. Single perf film works in mine, if the perfs are towards the bottom of the camera. In the picture the open camera lies on its top.

jpg/16_mec_16_sb_IMG_0961.JPG
Cartridges open. You don't need to open them for feeding. You can just slide the film in via the slit, it's guided inside. Do not cut it too long, it might jam. If you roll it tightly before feeding, it helps a lot. As always, it has to be done in the dark or a changing bag. Loading the camera can then be done in subdued daylight. Don't forget to reset the counter, the film transport stops after 24 pictures. If the counter shows "0", the transport stops.

We have talked about reloading cartridges, but where do you get the film? One possibility is film for 16mm film cameras. There is good advice about it on internet, just google it. The film commes in reels, often 30m and even more. As you need only about 50 cm for a cartridge, a reel gives you a lot to shoot.

Another possibility is a film slitter. This lets you use any kind of film you already know from bigger cameras. It's a good choice in my opinion. You can either slit 135 or 120 film. From 135 film you can only cut one 16mm strip. If you have a Minox as well, you can cut a Minox strip at the same time for free. A 36 exposure cartridge gives easily 3 lengths of 50cm. 120 film is shorter. You can cut three 16mm strips from it, but it's only about 80cm long. The remaining parts of the strips can be used for shorter testing cartridges.

jpg/16_film_slitter_IMG_5173.JPG
This is a special slitter, built to my needs. It cuts 120 roll film to two 16mm strips and one 21mm strip as I own an Ajax F21 camera.

jpg/16_film_slitter_IMG_5174.JPG
4 razor blades cut the film easily.

jpg/8_film_slitter_IMG_5171.JPG
This is a 135 film slitter that cuts two strips of 9.2mm Minox film. From a 36 exposure cartridge you get 4 loadings.

jpg/8_film_slitter_IMG_5172.JPG
It could also be made to cut one 16 mm strip and one 9.2 mm strip, there is just enough room between the perforations.

With 3D printing slitters are easy to make or it's easy to find someone to do it for you. Just think about it well before you buy the one or the other.

jpg/8_16_film_slitter_IMG_5175.JPG
Both models.

 As we already talked about Minox, we will at last have a look at a non-16mm cartridge, the famous Minox cartridge. It's for 8mm format on 9.2 mm film. Here they are

jpg/8_minox_cartridge_IMG_4633.JPG
4 film boxes with cartridges, one is empty.

jpg/8_minox_cartridge_IMG_4634.JPG
They are similar to the Minolta cartridges, capstain driven.

These are reloadable as well. You will need a film slitter to get 9.25mm film.

In general: If you need a spool for your camera, look for offers of cheap or broken items that come with a spool or cartridge. Ask the seller, if the interior is not shown. Single empty cartridges tend to be too expensive. Expired maker's film can also be a source.

I wish you patience and perseverence loading film. Once you're used to it, it's easy. It might help to waste one strip of film to try in daylight and get a routine. A 30m reel gives you more than 60 cartridges. So let's enjoy these old little camera beauties.

Some hints for 16mm developping reels are here.

Some results from expired film. This section might be updated if I come across more of it. At the moment it's a very cheap scanner which has a 16mm mask. As soon as Lomo gets a new batch of their Digitaliza mask to be shipped with their new 110 film ready, I will test the film and scan the photos on a better scanner. Nevertheless you can see what you may get from old film. The scans have been reduced in size for this page.

Minolta 16 100 ISO film, expired in 11/1973:

jpg/16_minolta_100_05.jpg
Scan w/o post treatment. Calais, quartier Mollien.

jpg/16_minolta_100_08.jpg
Scan w/o post treatment. Calais, quartier Mollien. The film is quite o.k. for a film which is more than 45 years old. But it has reached its limits. The emulsion is flaking off in some areas (top, right in this picture) and grain is clearly visible. But it's still fine to test your camera. I developped it with Rodinal 1+25, 9 minutes at 20° (as if it were 80 ISO).

Minolta 16 320 ISO film, expired in 1/1976:

jpg/16_minolta_320_17.jpg
Scan w/o post treatment. Calais, quartier Mollien. Heavy grain, as expected. High grade film wasn't that good in those days. High grade film doesn't keep as well as low grade film in general. For a 43 years old film it's fine. I exposed it as 250 ISO and developped it with Rodinal 1+25, 8 minutes at 20°.

jpg/16_minolta_320_17k.jpg
Scan with contrast encreased (30%). It helps but also increases the grain. It creates an extreme "blow-up" look.

jpg/16_minolta_320_08k.jpg
Another one with contrast encreased.

Svema 65 film, 65 ISO, expired in 12/1993:

jpg/16_svema_65_21v.jpg
Scan with scanner put to "lighten", but w/o post treatment. Calais, quartier Mollien. Although much younger than the Minolta film, this is not usable any more. All you get is a grey film base with a darker gray picture on it. I exposed it as 50 ISO and developped it with Rodinal 1+25, 7 minutes at 20°. Old Svema film doesn't have the best reputation. I will try another batch later.

jpg/16_svema_65_21vk.jpg
Scan with contrast increased by 30%. Doesn't help much and makes the uneven parts more visible.
