Abstract
A camera assembly has a support that defines an optical axis. A traveler is movable along the optical axis between first and second positions relative to the support. A turret is disposed in and movable with the traveler. The turret has a primary aperture. The turret is pivotable relative to the traveler, between a first position in which the primary aperture is spaced from the optical axis, and a second position in which the primary aperture is aligned with the optical axis. The turret can have a secondary aperture that is aligned with the optical axis when the primary aperture is in the first position. An over-center mechanism is switchable between a first state, in which the over-center mechanism biases the traveler and turret into respective first positions, and a second state, in which the over-center mechanism biases the traveler and turret into respective second positions.
