Canon Tele Converter TC-DC58B

The PowerShot S2 IS accepts the Tele-converter TC-DC58B, which increases the focal length of the master lens by 1.5x to 648mm (35mm film equivalent) at telephoto and the Wide converter WC-DC58A, which reduces the focal length of the master lens by 0.75x to 27.0mm (35mm film equivalent) at wide angle.
In order to attach these accessories, the Conversion Lens Adapter LA-DC58E is necessary.
