13.2 Flash photography on Contax 645
Use of flash sync cable
No cables are required between the P+ back and the CONTAX 645.
Flash sync cable must be connected to the CONTAX 645 camera.
The ash sync cable must NOT be connected to the P+ back. This
connector is only to be used when operated on a Large format camera
with the Phase One FlexAdaptor.
TTL flash
Because the CCD element reects light different than lm, and this cannot
be communicated to the Contax. Using TTL ash with the CONTAX 645
camera and P 65+ back, will result in a 2 f-stop overexposure. When
using TTL ash, the exposure compensation on the ash unit must
therefore be set to –2 f stops.
