I've got a compound shutter I'm scared to touch. I have found a resource, but I really don't want to "fiddle" with this baby. Seems like it's already on the edge of death.
"B" is for bulb, yes?
Then what is "M" and "N"? It came from europe so these might be german abbreviations?
There doesn't seem to be a button to open the shutter for focusing, either.
