“ Going digital
There are no moving or electronic connections between the Photomicro Adapter L and the Olympus OM camera body, so it is easy to adapt digital camera bodies that are less deep than the OM, and Canon EOS digital SLRs are often used. The most suitable are the EOS 5D Mark II and EOS 6D, because they have a sensor the same size as 35mm film.

Olympus OM camera bodies and the SC 35 Type 12 scientific camera have a register distance of 46 mm from the film plane to the front surface of the mount for lenses. Canon EOS digital SLRs have a corresponding distance of 44 mm, and so they need an adapter 2.0 mm thick when they are used to replace an Olympus body. It is not possible to make an adapter for Nikon F camera bodies that maintains parfocality, but replacement rear lens mounts are available. „
