  Single Frame Shutter for the ARRIFLEX 435

 

The newly developed single frame switching device for the ARRIFLEX 435 now offers a comfortable control for exposing single frames.

With the new single frame hand control unit a multitude of parameters can be pre-programmed. Access to all individual frame functions is possible via an RS 232 interface.

Also developed recently is the Integrated Capping Shutter which considerably simplifies work compared to the other capping shutters currently in use.
   
 

Single Frame Hand Control:

With the robust hand control unit, the following functions can
easily be controlled and set:

  • exposure time from 1/8s to 999s
    with a camera shutter angle of 180°.

    With a camera shutter angle of 11.2°
    the shortest exposure time is 1/128s

  • intervallometer operation with intervals of 1s to 99 hours, 99 min.

  • repeat counter (burst) from 1 to 99

  • fully automatic control of the ARRI Integrated Capping Shutter

  • signal output to activate an external Capping Shutter

  • trigger input

  • automatic signal to switch on light sources in intervallometer operation

  • signal output to activate a flash

  • input to the socket for an external light meter to match exposure time
    to the current lighting conditions
   
 
 

Integrated Capping Shutter:

On reflex cameras the mirror shutter usually is not sufficient for lengthy breaks between two frames - the shutter is simply not lightproof enough.

Therefore, for single frame shots, normally an extra capping shutter is attached in front of the lens and is opened only for the time of the single frame.

This, however, has the disadvantage that the image cannot be viewed through the viewfinder as long as the capping shutter is closed. To avoid this, ARRI has now developed a newly patented capping shutter.

The main feature of the new Integrated Capping Shutter is a shutter which is attached behind the mirror reflex shutter, thereby preventing light from falling on the film. With this principle, it is always possible to look through the viewfinder. With the ARRI Integrated Capping Shutter the time between exposures has been extended with respect to the light-tightness of the shutter assembly to approx. 1 hour.

A further advantage is that the area in front of the lens, for example for filters or a mattebox, remains free.

This new solution displays compactness and a considerably quicker reaction time compared to normal capping shutters.
