Can Canon EF 35-80 Old Zoom take 35mmX35mm image on 120 film without problem ?

There may be vignetting at the widest zoom setting. If this is the case, I expect this to be mostly gone by about 45mm.
One of they key issues with this lens for use on 120 film is that if you want a functioning aperture, you'll have to electronically control it, for instance with a butchered Canon EOS camera. If you're OK with only using it wide-open, you can ignore this.

Hello Koraks , Can I set the aperture to f:22 in the camera and remove the lens with setting in this aperture or removing the lens makes set to f:4.5 or so ?

 

[koraks]

You can indeed use a camera to set the aperture to f/22. Mount the lens on the camera, turn on the camera, then set the aperture to f/22 and press the depth-of-field preview button. If the camera doesn't have one, make a photo with a long shutter speed. While the aperture is stopped down, remove the lens from the camera. The aperture will then remain stuck at this value.

Thank you very much indeed , this saves the day. Thank you.

Great, have fun with the experiment!

DIY Swing Lens 120 Film Jeff Bridges inspired Camera with Canon EF 35-80 - Which Format Should I go ?

I loved the attitude of jeff bridges to widelux cameras and I found his idea a widelux is between cinema and photography. It takes time photographs really.

As a poor folk , I found a canon ef 35-80 zoom lens and I want to take 35mm high format swing pictures with it when the lens set to f:22 and the zoom to 35mm.

I want to learn your wildest ideas what format should I go , 35mm X WHAT ?

 

[OAPOli]

Nominally, the lens will cover a 43mm circle. Some lenses have a rectangular baffle at the rear which may vignette the circle. 35x35mm fits in a 49mm circle.

This choice of lens is an awkward one to make a DIY camera.

Would a cheap prime such as the 28mm f/2.8 not give better results than the 35-80mm ?
Coverage wise and general image quality .
I say 28mm rather than 35mm as 35mm lenses tend to be f/1.4 and expensive.
I'm not sure if Canon do a cheap 35mm .

Aperture wise , would a larger than f/22 not be better to avoid diffraction?
If you need f/22 due to the shutter speed being long , put an ND filter on the lens to reduce the light entering it to offset an aperture one stop brighter .

Just a few thoughts that might be of no help .....
Enjoy your experiment, hopefully it'll give you what your interested in.

Coverage-wise almost certainly not since it's a shorter lens so the image circle will be smaller, as it will definitely not be any larger than strictly necessary to keep cost, size and weight down.

I'm not sure if Canon do a cheap 35mm

EF 35/2.0; an oldie, should be available fairly cheaply second hand, but the 35-80 can probably be had for free.

I forgot the f/2 .

F22, swing lens camera?
Since that would likely be tripod mounted, why not make a medium format pinhole camera with curved film plane?

 

[koraks]

why not make a medium format pinhole camera with curved film plane?

The film plane on this idea is so curved that we've now gone full circle!

Which is sharper ? 6X17-24 Curved plane or 6X17-24 Anamorphic

Which camera is better and sharper edge to edge. curved plane pinhole camera or anamorphic pinhole camera ?
