15.4 Hasselblad 555 ELD
Ensure that the shutter release on the front of the Hasselblad 555 ELD is in
the DIG position when using a Phase One IQ back.
If for any reason you have to use the 555ELD in Film position (E.g. If the DIG
is not working) then set the IQ to Zero Latencey.
Shutter Latency Setting
The IQ back can be used with both Normal and Zero latency with the
Hasselblad 555 ELD.
An IQ back has a default Normal latency setting that helps to save battery
life. But users may experience unwanted double exposures when using a
two-shot release cable.
Motor Cable on Hasselblad 555 ELD
A motor cable is not required when using an IQ back on a Hasselblad 555
ELD body.
