Canon EF-M body + Canon FD lens
COMPATIBLE MF MA
Conversion is entirely possible.
The FD is an SLR system, which leaves ample space for mounting on an EF-M mirrorless. There's only one tricky part, the aperture control of the FD: this is a ring on the adapter that allows opening and closing the diaphragm of the FD lens independently from the pre-set value (usually marked with OPEN-LOCK). Keep it closed, unless you like to be surprised when taking pictures.
Find your adapter here:The "Canon FD bayonet" may actually refer to three different things, and although these mean no difference in using the adapter, they're worth a mention. The FL bayonet was the predecessor of the FD and could have been fitted on cameras (and adapters) using the FD bayonet lock. The FD bayonet has two versions: FD and nFD. The original FD has a breech lock, which means that only the silver ring on its end of the housing moves when fixing it (it doesn't have a lug, it tightens onto the bayonet lock). In the case of the nFD the whole housing of the lens turns when fixing (similar to a modern EF lens), but the bayonet itself doesn't turn inside the compartment (and has a safety release as well). There are 134 types of FD and 33 types of FL lenses, all of which can be with all kinds of FD adapter rings.
