A: Olympus lenses with a Micro 4/3 mount can fit a Panasonic camera with the same mount. However, this mount is for the older Olympus OM SLR lenses. If you intend on using a telescope or spotting scope with a Panasonic camera with a Micro 4/3 lens mount, then the Kowa TSN-CM2 T-Mount Camera Adapter Ring (Micro Four Thirds), BH # KOCM2M43 is needed. https://bhpho.to/2T1qKCo
