Canon WL-DC100 remote control

WL-DC100 infrared remote controller can be used up to approximately 5m directly in front of the camera to shoot or control playback. The WL-DC100 is compatible with PowerShot Pro90 IS and G1. (This is a replacement part for the item that is included in the PowerShot Pro90 IS and G1 Kits.) The WL-DC100 lets you operate the zoom lens and trip the shutter (with a 2-second delay) when in shooting mode. In replay mode it can be used to move forward or backward through the images, play a movie clip, magnify a still image and pan around inside of it, toggle the display mode or call up the index mode
