Modified kodak no 3-a for 120 panorama's
Using a 122 to 120 film adapter it's probably the cheapest option to shoot 6x14 panorama's.
Replaced the kodak lens with a 105 mm lens from an old Kinax camera
Jammed shutter
The original Kodak lens had a shutter that wasn't working. So I replaced it with a 105 mm lens hoping it will cover the big negative size. Taping a piece of tracing paper or wax paper to the mask where the film is exposed, you can create a 'ground glass' to test your lens coverage and meassure the new infinity point of focus.
A clip from a fotofame as the new infinity point
Recallibrate focussing
To mark the new infinity point I glued a clip from a fotofame as a stop to the ground plate. When extending the lens it will now stop at the new infinity mark. I might try some marks for closer focus in the futere but for now infinity is what I will use for panorama's using this camera.
Vilt on the back and red transparant inlay
Camera back modifications
The camera back has no pressure plate. I glued some vilt to the back to tighten the space between the mask and camera back. Also I applied a transparent red sheet in the autographic window. The window is now used to view the frame numbering when advancing the film.
Smaller mask to fit 120 film.
Film mask adjustments and 120 spool adapter
A smaller film mask for the 120 film made out of an acrylic sheet painted black. And a 122 to 120 film spool adapter. I bought my adapter in Italy at camerhack.it. Check this gallery for some panorama's made with this camera
