Shooting with a two-shot release operation
The IQ Digital Back is equipped with two shutter latency mode settings;
Normal and Zero latency. With the IQ Digital Back set to Normal latency,
because of the “sleeping” architecture of IQ Digital Back, the digital back must
be triggered twice to provide the sensor a “wake-up” signal before it can
initiate the capture.
The advantage of using Normal latency is that the sensor does not have to be
awake at all times. This both saves energy and makes sure that the sensor
temperature doesn’t rise unnecessarily over time, potentially degrading image
quality by causing unwanted noise.
This operation requires a special two-shot sync cable. The first release
activates the IQ Digital Back with the wake-up signal, and the second initiates
the exposure. There are several automatic, or semi-automatic, two-shot
solutions (sometimes referred to as wake-up cables) available for use with a
mechanical shutter.
Connect one end of the Wake-Up Cable (part number: 50300131) to the flash-
sync port on the lens’ mechanical shutter and the other end to the Multi Conn.
to Mini Jack Adaptor Cable (part number: 50300144). Then connect the sync
cable to the multi-connector port on the IQ Digital Back.
Ensure that Shutter Latency is set to Normal mode on the IQ Digital Back
under IQ Menu > Camera > Shutter Latency > Normal.
