Canon Wide converter WC-DC58N f PS G3 Black

To broaden the angle of your view, the Wide Converter WC-DC58N is available for the G3. Or if you want to pull back a little more, Tele-converter TC-DC58N is available. Both accessories require Conversion Lens Adapter LA-DC58B to be used with the camera.
This lens converts the master lens' focal length by a factor of 0.7, creating a focal length of 24.5mm for grand panoramic vistas.
