Canon HF-DC2 Flitser
The Canon HF-DC2 High-Power Flash is an additional flash unit for PowerShot cameras that operates wirelessly and increases the effective flash range up to approximately 30 feet. It covers an area equivalent to that of a 24mm lens in 35mm format. The HF-DC2 flash is supplied with a mounting bracket so it can be attached to the camera, but it can also be hand-held or mounted on a tripod or accessory light stand to adjust the lighting angle for professional-quality results. Multiple HF-DC2 units can be synchronized with a single camera for even greater lighting flexibility. This smart high-powered slave flash unit is compact and compatible with almost every PowerShot digital camera (except for the G1 X, SX1 IS, SX40 HS, SX30 IS, SX20 IS and SX10 IS).
