Ikelite 6870.40 for Canon EOS 40D Webcam User Manual


 
Using External Strobes
This housing has Conversion Circuitry built into the camera tray.
When used with Ikelite DS Substrobes the Conversion Circuitry
provides real Canon eTTL flash exposure with over and under-
exposure compensation of two f-stops in half-stop increments.
The Conversion Circuitry also offers Manual exposure control
with 31/2f-stops of under-exposure control in 1/2 stop
increments.
The Conversion Circuitry is powered by the Ikelite DS Substrobe
when connected to the housing with the #4103.51 single or
#4103.52 dual sync cord.
See page 12 for DS Substrobe compatibility with the Conversion
Circuitry.
NOTE:
If the camera is busy with a function such as displaying a
photograph on the LCD panel the Conversion Circuitry cannot be
accessed to make changes. Wait until the camera has finished
with any activity before making changes through the Conversion
Circuitry.
