Canon WD-H58W Overview
The Canon WD-H58W Wide Converter Lens is optically matched to go with the XA10 HD camcorder, but it is also compatible with other Canon camcorders and can be attached to any lens with a 58 mm filter thread. The WD-H58W brings a wider angle of view to your images and either 0.7x or 0.8x magnification may be printed on the lens. The WD-H58W is a great investment if you're looking to pack more of your subject into the frame. This is useful if you're shooting groups of people, small rooms, or wide landscapes.
Canon WA-H82 Overview
Canon's WA-H82 0.8x Wide Attachment Lens is designed to provide a wider angle of view for XF300 and XF305 pro camcorders, turning each camera's 29.3mm lens into a roomier 23.4mm (35mm equivalent). That means you can take in far more of a scene, especially indoors or in tight spaces.
Canon WA-H58 Overview
The Canon WA-H58 Wide Attachment Lens is a 0.75x wide angle converter for the Canon Vixia HF G30 and Canon XA20 and XA25 cameras. The converter attaches to your lens and effectively makes your lens wider, giving you a greater field of view. When using the converter, the camera's lens must be zoomed out fully, otherwise the image will be out of focus. The converter weighs less than 3/4 of a pound and comes with a lens hood to protect your image from flare.
