It equips the 40D or 50D with a portrait grip for comfortable shooting in this aspect ratio, along with wireless networking and USB connectivity options.

The unit is weather-proofed and built to the same standard as the 40D / 50D body.

Here’s the WFT-E3(A) unit pictured from the front. Two metal pins guide the unit into the base of the 40D or 50D body, and a tripod screw turned to securely attach the pair. At the back you can see the data connector.

This shot of the WFT-E3(A) mounted on the 40D shows the duplicate controls for use in the portrait orientation. Along with the shutter release at the front, there’s a duplicate finger dial, AF-ON, AE lock and AF point selection buttons. The On / Off switch can be used to disable these controls, but still keep the unit’s other functions operational.

The WFT-E3(A) uses a single BP-511A battery, not supplied. This is only used to power the unit and cannot extend the 40D or 50D’s battery life.
