Flash / Strobe
The CFV can be used together with most studio or portable units.
When attached to a 503CW, the TTL function is also available.
Most flash units are suitable for use with the CFV. However, for the sake of safety, care should be taken when using studio flash units (strobe) and tethered to a stationary computer.
Portable units
Attach the flash sync cable to the lens (or camera body in the case of a Hasselblad 200 series model) and make the appropriate settings according to the unit.
This also applies when using studio units when:
a)tethered to a computer not connected to a regular electricity supply system.
or
b)tethered to an Imagebank or laptop computer running on batteries.
With studio type flash units (strobe) and tethered to a computer
If the CWD is tethered to a computer that is connected to a regular electricity supply system as well as a studio flash/strobe unit that is also connected to a regular electricity supply system/generator system, then make the following connections instead:
a)Connect the flash sync input cable from the sync contact (PC connector) on the lens to the flash sync IN terminal on the back.
b)Connect the flash sync output cable from the flash sync OUT terminal on the back to a regular flash sync cable that is connected to the unit.
TTL function – 503CW only
A TTL function is only available with the 503CW. The reflective characteristics of the digital sensor are different to film surface characteristics for which the TTL function was originally designed. However, by changing (in effect, ‘tricking’) the setting, TTL exposures can be made. Proceed as follows:
Move the ISO selector on the 503CW so that is becomes approximately 1⅔ f/stop higher than the ISO setting on the CFV. Therefore, for example, when the back is set at 50ISO, the ‘film speed setting’ on the camera should read 160ISO, and so on. Testing for the most suitable compensation that suits you is recommended.
See appropriate manuals for connection details regarding the various units and adapters.
