Abstract
A camera system including a matte box assembly for use on cameras for supporting a plurality of filters, the matte box assembly includes a support bracket which supports the matte box and which (1) axially translates toward and away from the lens and (2) in a separate action, once it has been axially translated to a given position away from the lens, the support bracket pivots 90.degree. away from the lens. The assembly includes a crank arm for actuating both the axial translation and the pivoting action sequentially.
Claims28
A matte box assembly for a camera, comprising
- a main bracket;
- a first support section supported on the main bracket and axially translatable thereto;
- a second support section supported on the first support section and axially translatable thereto;
- a matte box movably mounted on the first support section about a first pivot;
- a link arm having a first end pivotally connected to the second support section and a second end pivotally connected to the matte box at a second pivot offset from the first pivot.
A camera system comprising:
- a camera;
- a camera support upon which the camera is removably mounted;
- a lens assembly removably mounted to the camera;
- a matte box assembly movably positioned in front of the lens assembly, comprising
- a main bracket,
- a first support section mounted to the main bracket and axially movable thereto,
- a matte box pivotally mounted to the first support section,
- a drive mechanism for axially translating the first and second support section a desired amount within a predetermined range and once the first support section has been translated the predetermined range, for pivoting the matte box away from the camera.
A camera system including a matte box assembly for use on cameras for supporting a plurality of filters, the matte box assembly comprising matte box and a support bracket which (1) supports the matte box and which (2) axially translates toward and away from the lens and (3) in a separate action, once it has been axially translated away from the lens, the support bracket pivots 90.degree. away from the lens, the matte box assembly including a crank arm for actuating both axial translation and pivoting action of the support bracket sequentially.
A method of controlling position of a matte box assembly for use in front of a lens on a camera, comprising the steps of
- operating an actuation mechanism to axially translate the matte box to a desired position between a fully contracted position to a fully extended position;
- operating the actuation mechanism to pivot the matte box assembly away from the lens, the actuation mechanism sequentially translating the matte box to the fully extended position and then pivoting the matte box away from the lens.
A matte box assembly for a camera, comprising
- a main bracket;
- a first support section supported on the main bracket and axially translatable thereto;
- a drive mechanism including (a) an axial drive mechanism for axial translating the first support section relative to the main bracket, and (b) a pivot mechanism for pivoting the matte box on the first support section selectively toward and away from the camera, wherein the drive mechanism comprises a single actuator which operates both the axial translating and the pivoting of the matte box.
