Mounts to front of lens via bayonet in place of factory shade.

The Century .7x Wide Angle Adapter attaches quickly to the front of your XL 16:1 zoom lens, offering a 30 percent wider angle-of-view and full zoom through capabilities.

The .7x shifts the focal length range from 5.5–88mm to 3.85-61.6mm with no appreciable light loss.

Canon's 3x zoom lens is compact and useful, but imagine switching those delicate electronic lenses quickly on a wet day at the beach. . .The Century .7x Wide Angle Adaper slips onto the front of your Canon 16x Manual Zoom with a one-handed twist.  It will give you an effective focal length nearly as wide as Canon's 3x lens (within half a millemeter) and zooms six times as far.

For Canon XL-H1 with 20X zoom lens and Canon XL2 with 20X/16X Servo Lens AF.  Mounts to front of lens via bayonet, in place of factory shade.
