The lens adapter connects your lenses with an M42 connection to cameras with a MFT connection. Due to the precise and accurate assembly, the adapter securely locks into the bayonet connection of your camera.
The connection is entirely mechanical, so no electronic data transfer takes place. Thus settings regarding f-stop, focus, etc. have to be made manually. Focusing to infinity can be done without any problems.
Please note: to connect lenses with a bigger rear-mount (f.ex. Wideangle-Lenses) is mechanical not possible.
