The PowerShot S70 uses the same "UA" lens design as the S60, which allows Canon to make the camera thinner while adding more zoom power. This lens is also wider than most, with a focal range of 28 - 100 mm (5.8 - 20.7 mm in "digital terms"). The maximum aperture is F2.8 - F5.3. As I mentioned in the previous section, the camera supports 37 mm filters as well as a 2X teleconverter through the use of the conversion lens adapter.
