what does NON-Perforated film adapter look like?

K2adie · Apr 20, 2016

hey, sometimes I find bulk with with no holes on them (NON-Perforated)
I was going to throught and saw some people mentioning they bought an adapter for their cameras, so it can use NON-Perforated film.

After about 2 hours of google searching, I cannot find a single photo of it.
If you have one, or a modified camera, please take a photo of it and upload it. I want to see one to build one.

I have meters of portra film with no holes, both in 35mm and 70mm and I'm just looking for an adapter or some way to use it with my nikon's and hasselblad.

thanks

I've not heard of an adapter, but I have heard of bodies that do not use sprockets to advance the film or control frame spacing. Apparently there are 35mm cameras out there -- motorized/electronic -- that advance the film and in some manner count the sprocket holes, or have the motor advance only as much film as needed based on calculating the changing diameter of the take-up spool caused by additional layers of film. I've also read of people who put tape over the sprockets so the unperforated film can slide over them more easily.

I read some people had adapters for their hasselblad backs, some did for 35mm. Some people have them modified but I have never seen any of it. I can probably make or 3d print one but i need to see a working project once

The Canon EOS 10S/10QP can shoot non-perf film with no problems. Just tape the leader to the take up reel and away you go.

I have heard about that camera, I dont like digital film cameras that much. I like Fm2, F3, Fm3a and such... and suggestions on a similar one?

I have no idea how your Nikon works, let alone the Hasselblad, but sacrifice some film to experiment.
Just try it and see how it works in your camera, at least the 35mm. With no film, open the back and turn the advance. Does the shutter cock and sprocket wheel move with no film? If so, you might be fine.

I have a Sears KS-2 (Ricoh XR-7), and have run non-perfed film through without a problem. The backing plate holds the film flat enough, and the sprocket wheel and shutter cocking mechanisms are driven by the advance mechanism - not by film moving them. You may end up with inconsistent frame spacing, but they should not overlap.

I have a Konica Autoreflex T which was modified for use with unperforated 35mm film. Instead of sprockets moving the film there are rubber rollers where the sprockets used to be.

There are discussions in forums about Hasselblad 70mm-back conversion for unperforated film. But no details. i filed down dents of the film-counter. Yes it does not transport film but rotation tells the mechanisme how to transport. must find out how it will behave over full lenght. No problem if only a few images are transported. but i have no camera. There were problem with ELX motordriven images. But in the discussion is said that a rubber ring is added where these dent were. so a specialist must take apart this axis and execute the steps. Graflex RH50(67/70mm) is using DP and UP films Double and unperforated films.
I have this Canon EOS 10s. xkaes at aol dot com can deliver all kind of slitters. I am cutting down 70mm when not available in 35mm. i have a center 7035 slitter. and one cutting only center-part to avoid perforation. One can cut 120-size from one side. one -side perforation will stay to not interfere with machines when cut inbetween(on both sides).

Can you please upload a photo of it?

I have modified a Nikkormat Ftn by adding sufficient textured rubber tape to the sprocket spindle that it provides friction to pull the film along. Negative spacing is non-standard, but it works a charm. Very cost effective.

828 shooter here. If you can't get this to work or just want to hook a brother up, please tell me where you get this non-perf 35mm if it's B+W, or sell me a roll! I'm running low on my non-perf stock!
