RZ67 + 50mm on 16mm film So this is 16x70 format

16mm through a 6x9 back on a 2x3 Century Graphic. Seems I'm not the only one doing this kind of thing.

Well, you only get 6 shots a roll, so it won't be TOO hard.

Or you convert a Kodak 122. Then you will get 4 shots a roll, 56x138mm https://www.oddcameras.com/122_120_adapter.htm. That's still easier...

So sorry, we get away from the 24 shots a roll.

All those moments will be lost in time, like tears in rain...

This is the tech I needed 20 years ago! Thanks for the tip.

Until 3D printing was cheap(ish) converting old bigger format cameras to use 120 wasn't a very practical exercise. Mind you, I've seen 116 and 122 spool ends attached to a 120 spool, but they weren't something you could just order after a quick Google search...

I’ll be fetching my old Kodak folders out of storage next week! Soooo excited.

I have a Kodak Monitor 616 here somewhere. Its a beautifully crafted thing which as I recall, winds to the next frame without needing a red window.

Which function may or may not work with 120 film.

I have a Kodak Reflex II with automatic frame counter, but the counter is driven by a friction wheel -- a toothed wheel at the edge of the roller at the takeup end of the frame gate; this rides in the rebate of the emulsion side of the film. I also have a Bantam RF that uses a similar wheel riding the rebate of 828. Assuming Kodak stuck with a system that worked, you may find the 120 film fails to drive the counter mechanism in your Monitor 616.

choiliefan · Jun 13, 2023

Now that you mention it, pretty sure the counter on my Medalist II works the same way.
My curiosity is piqued re the Monitor and will endeavor to dig it out this weekend.
Thanks Donald.

I just need to source some 616 paper and I can roll 70mm into it.

I dont really understand this. Are we talking about the adapter for 35 mm film or the adaptor for 6x4,5 cm (the one mentioned by the poster before)?

The Rollei 24 frame kit is for 120 film. It has a counter geared for 24 frames. As I understand choiliefan's post, he took the internal film mask and opened it up to each side. Here's an Ebay grab of a kit. The internal mask is the lower right frame that locks inside the camera.

The guy who invented the scissors also invented this method, even before photography. (He not even needed to mask, as he was smart enough to recognise, that it is more flexible to cut from the image after it is made.)
Rollei had an adaptor that did exactly this without wasting film. It consist of gears with a lower number of teeth that you install into the camera so it advances not a complete frame height but only half. You get 16 frames on a roll of 120 film. The set comes with mask for the film gate, the viewfinder and the sunshade.
A similar adaptor exist for the Flexaret.

24 frames per roll of 120. I'm sure Leonardo D was cropping his paintings with a pen knife but I'm no Leo and I don't really like cutting up my negatives.

I've gotten closer to 30 exposures on some rolls btw.

I found another odd TLR (Kallovex) that natively supports 24 frames on 120 film, as well as proper masks on ground glass. So I made a 24x52 pano mask for the film gate, and now I can get 24 frames of pano.

To the OP; I'm not sure how I missed this thread. This is interesting stuff.
@blee1996 I'm trying to thin down my number of cameras dang it.

Mike, there's always cropping.

Indeed. I've cropped some of my Hasselblad shots (what!? the horror...) to great effect.

Where did you find this thing? I've moved past this 6x3 project but this camera looks really cool.

I got it from a local camera swap, out of curiosity. But after some research, it seems to be quite rare. From the serial numbers I collected across the web, there are probably no more than 1000 made in total.

@blee1996 nice find! There is very little info about this camera online. You should write a camera-wiki article to fill the gap .

I'm collecting all my research into notes, so later I can add an entry to camera-wiki. But many wiki needs reference, and I don't have a lot reliable sources.

One can get the format that the OP desires, but will never reproduce the wide angle and correct rectilinearity of a Hasselblad SWC.

Camera west has one. I'm not sure I would call their asking price cheap, but they have one.

Uhhh...Nope. Gotta eat. If I somehow become the next Leibowitz or something I'll be sure to pick one up.

Sorry to disappoint, but that Kalloflex on Camera West is not Kallovex. Similar name, but different mechanisms.
