I have Olympus OM-1n and I love Metz Mecablitz 45 CL-4 analog when used as bounce flash. With manual focusing lenses, I am so used to left-hand focusing but this flash have left-hand grip which makes hard if not possible to focus with right-hand + cock the shutter + release.

I am thinking to fit an additional focusing ring with a handle to turn, if something like this is available.

How you guys are managing it?
