It only goes up 125th so it seems like it is a press shutter.
I can't figure out how to close down the aperture to say f22 or f32 to check focus, instead of wide open. I read you should set it on B(ulb), but can't figure what to do next.
If I open the lock on the cable release and depress slightly, I can close the aperture as much or little as I like and hold it there, but I don't know what aperture it is exactly.
