Lesson 10: Variations on The Escapement Retard

This lesson expands on your knowledge of shutter mechanisms by introducing shutters built into the camera body, rather than the lens. It also introduces the unique "Double Escapement Retard" system used the Ilex Acme leaf shutters used on some older large format lenses.

As with previous lessons, there is a Study Procedures guide, a Lesson Text, and a Quiz. Read the Study Procedures first, then the Lesson Text.
