Canon EOS 20D DSLR Digital Camera Press Release

The EOS 20D has a newly developed shutter with a top speed of 1/8000 sec., user-settable in 1/3 and 1/2 stop increments (in shutter speed priority AE and manual modes) and a maximum flash synchronization speed of 1/250 sec. First or second curtain flash sync is possible. The shutter’s APS-C configuration allows a reduction in the size of the unit, smaller shutter blades with lower inertial mass, and shorter travel distance. Stronger magnets are used for each shutter curtain, permitting better control of the blades. A semiconductor switch replaces the traditional sync contacts, ending scorching and frictional wear while at the same time increasing the limit for trigger circuit voltage to 250V. The result of these changes is a more rugged and reliable shutter unit with substantially improved performance.

EF and EF-S Lenses

Particularly among advanced amateur and professional photographers, there has been a growing need for affordable zoom lenses that support true wide-angle and ultra-wide-angle photography. In response to this market demand and to provide users with a truly comprehensive lens system, Canon has expanded its EF-S lens offerings to now include four lenses – the new EF-S 10-22mm f/3.5-4.5 USM and EF-S 17-85mm f/4-5.6 IS USM zoom lenses as well as standard and USM versions of the EF-S 18-55mm f/3.5-5.6 zoom lens. (Canon U.S.A., launched the standard EF-S 18-55mm f/3.5-5.6 zoom lens in August of 2003 in conjunction with the EOS Digital Rebel SLR.) The EOS 20D digital SLR is also fully compatible with all Canon EF lenses and with the entire system of Canon EX Speedlites and accessories, including the new Speedlite 580EX flash.
