Canon has unveiled two new additions to their EF-S line of lenses designed specifically for the EOS Digital Rebel/300D and EOS 20D.
The EF-S 10-22mm f/3.5-4.5 USM provides a field of field that's roughly equivalent to a 16-35mm lens on a 35mm film camera. The variable maximum aperture, however, may limit the appeal of the lens for some. It has an estimated street price of US$799.
The EF-S 17-85mm f/4-5.6 IS USM has about the same field of view as a 28-135mm lens on a film camera, and has an estimated street price of US$599 in the US.
Canon USA, Canon Canada (and perhaps other regions as well) will also begin selling the USM version of the EF-S 18-55mm f/3.5-5.6 lens that has been part of the EOS Digital Rebel kit lens since that camera's debut in 2003. Up until now, neither the non-USM version (which is the version in the Rebel kit in North America and several other regions worldwide) or the USM version (which is the one bundled with the camera in Japan and possibly elsewhere too) has been available for purchase separate from the Digital Rebel. The EF-S 18-55mm f/3.5-5.6 USM has an estimated street price of US$169 in the US.
All three EF-S lenses are slated to ship sometime in the fall of 2004. Press releases from Canon USA and Canon Canada have more information on the new lenses as well as the USM version of the EF-S 18-55mm f/3.5-5.6.
