Tilt-Shift Adapter for Canon EF and FD lenses to EOS-M and Micro Four Third Systems

thingiverse

Here is a Tilt-Shift Adapter that can be configured to attach Canon EF or FD lenses to an EOS-M camera. Old FD lenses will allow for selecting the f-stop, while EF lenses will provide wide open aperture and detailed control of depth of field for miniature style photography. I've always wanted one of these adapters, and I was also curious about whether it's possible to print in the required precision and create a functional adapter. Shift and tilt can be set between plus/minus 10mm and 10 degrees, respectively. I use it with the EF 24 mm L 1,4 II or the FDs 85mm 1.8, 135mm 2, 24mm 2.8, or 50mm 1.4. Integrated a lock for EF lenses that uses a spring from a pen and the adapter will also lock onto the EOS-M. To mount an EF lens, tighten the rotation stop to secure the adapter in place. To mount an FD lens, first insert the lens with the red marker at a 45-degree angle to the right of the marker on the adapter, then turn left until the red marker lines up with the marker on the adapter. Press the lens down and turn right until it locks. This will engage the aperture lever. Even older Breech lock FD lenses will also fit, which can be set to manual aperture operation directly by pushing the lever counter-clockwise before mounting on the adapter. There is limited space in 26 mm for the mechanics, so I printed this in Carbon fiber PETG at 0.1 mm resolution and a 0.4 mm nozzle for strength and precision. Parts for the EF or FD version are labeled accordingly, with the rest being shared parts. Glue the FD 3 parts together to assemble the adapter. Tolerances are very tight to ensure a good light seal, so the surfaces need to be wet-sanded with a sanding sponge and 220-400 grid until everything glides smoothly together. If there is enough friction, you can remove the screw for the shift adjustment and have a quick adjustable adapter for handheld operation. Required screws include: 1x Hex head M4 40mm 3x Internal hex M3 50mm 2x Internal hex M3 40mm 1x Internal hex M3 30mm 3x Internal hex M3 20mm 1x Internal hex M2 8mm 3x M3 nuts 1x M4 nut 1/2 spring from a pen If you have any questions about assembly, please ask in the group. I also added an adapter for Micro Four Thirds Systems with an flange focal distance of 19.25 mm. It has not been tested as I don't have a M4/3 camera, but it might work - let me know if you try it.
