MOVIECAM Iris Control MCIN-604
PACKAGE CONTENTS:
- (1) MOVIECAM Iris Control MCIN-604
SPECIFICATIONS:
The Moviecam Iris Control MCIN-604 is a specialized electronic module designed for the Moviecam Compact (and Compact Mk2) 35mm film camera system. It is used to automate iris adjustments, particularly during speed ramping (changing the camera's frame rate during a shot), to maintain consistent exposure. [1, 2, 3]
Key Specifications & Features
- System Integration: It typically works as a component of the Moviespeed box or specialized accessory boxes that handle microprocessor-controlled variable speed operations.
-
Functionality:
- Compensates for exposure changes by automatically adjusting the lens iris as the camera frame rate fluctuates.
- Interfaces with external iris control motors (such as the Moviecam SRN 27/97) to physically move the lens aperture ring.
- Connection: It connects to the camera's Accessory Plug or specialized "Syncobox" module.
- Precision: Designed for high-accuracy synchronization, often cited alongside speed controls accurate to 0.001 frames per second. [1, 2, 3, 4, 5]
Operation Context
In professional cinematography with the Moviecam Compact, the MCIN-604 allows a cinematographer to perform a "speed/iris ramp." For example, if the camera speeds up from 24fps to 48fps (losing one stop of light), the Iris Control module will automatically open the iris by one stop to keep the image's brightness identical throughout the transition
