Description
Dulens EF mount for the APO Mini Prime 110mm
This replacement mount converts the Dulens APO Mini Prime 110mm from PL to Canon EF. It is the focal-length-specific version: select it for the 110mm, rather than choosing a mount kit simply because it belongs to the Mini Prime family.
Changing the mount and retaining back focus
Work on a clean surface, remove the PL mount using the correct tools and keep the original screws and shims with this lens. Shims set the optical distance to the camera sensor; losing them or changing their order can shift infinity focus. Fit the matching EF mount without trapping a shim, then check that the lens reaches infinity and that its focus marks agree with the image.
The mount changes the mechanical camera connection. Focus and aperture remain manual; it does not add autofocus or electronic iris control. A lens adapter on the camera is a different solution from replacing the rear mount on the lens.
