Eclair ACL Shutter (175°)

Eclair ACL Shutter (175°)

The plane shutter. In the ACL, unlike other reflex cameras where the mirror is also used as a shutter, a large diameter, plane shutter having an exposure angle of 1.750 operates in front of the film.

The shutter cuts off the image in the direction of the smallest dimension, i.e. from top to bottom, and is so shaped to ensure an even exposure.
