Size #00 shutters

Compur #00 and later Synchro Compur #00 seem to be the smallest of the standalone shutters ever made in series.

The shutter is quite rare, and we have only a few adapters for it.

Their main dimensions are:

• Front lens cell thread: M22.5x0.5
• Rear lens cell thread: M22.5x0.5
• Rear mount thread: M25x0.5
• Lensboard hole diameter: 26.3mm
