Ikelite 6870.40 for Canon EOS 40D instruction manual Using External Strobes

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.
