This adapter allows use of LTM lenses (39mm Leica mount thread) on the micro Four Thirds mount digital cameras.
The adapter is well made, all metal construction. It has a nice design feature - the inner part which accommodates the lens has three set screws. When the lens is installed, it can be oriented in the correct position, with the dials facing up, by loosening these set screws and turning the inner part. A small screwdriver is needed for the job.
The Jupiter-3, Jupiter-9 and Olympus E-P2 are show for illustration only and are not included.
