Designed for advanced amateurs, photojournalists, wedding photographers and professionals, the EOS 20D digital SLR combines speed, image quality and ruggedness with compact size and light weight to deliver the highest performance in its class. The EOS 20D has a new APS-C (15.0 x 22.5 mm) 8.2 megapixel CMOS image sensor designed and manufactured by Canon. It is the first mid-range digital SLR to offer high-speed continuous shooting of five frames-per-second with a burst of 23 frames at highest JPEG resolution. Very robust - the camera starts up in 0.2-second and has a shutter release time lag of only 65 milliseconds.

The all-new 9-point AF unit with high-precision cross-type sensor raises the bar on speed, accuracy and precision in mid-range SLRs. The new AF system has one full stop better low- light performance than its EOS 10D predecessor. The new E-TTL II autoflash metering system, inherited from Canon's EOS-1D Mark II professional model, takes into account the distance, reflectance and position of the subject for highly stable, accurate and intelligent exposure calculations.

The EOS 20D digital SLR is both smaller and lighter than the 10D model. The 20D camera is about 3.6 ounces lighter and Canon reduced the width, height and depth by 5.7, 2 and 3.5 mm, respectively. The shutter unit, mirror box, main mirror, pentaprism, focusing screen and viewfinder optical unit have all become smaller as they were optimized for the APS-C sensor. The 20D digital SLR has nearly 100 fewer parts than the 10D model. The new camera retains the rugged stainless steel chassis and magnesium alloy body covers of its predecessor for outstanding durability.

The new camera's combination of speed and available light shooting capability make it especially appealing to newspaper photographers. Aside from the five frames-per-second burst rate, the EOS 20D digital SLR delivers superb low light performance and exceptionally low noise, even at high ISOs. In fact, images taken at ISO 1600 are approximately equal in noise to those taken with the EOS 10D model at ISO 400.

The Canon designed and manufactured CMOS sensor has a maximum resolution of 3504 x 2336 pixels, which is sufficient for very large prints (up to 16 x 24 inches) with fine detail. Like its big brother, the Canon EOS-1D Mark II, the EOS 20D digital SLR satisfies the wedding photographer's benchmark: facial details in group-shots. With the speed and large buffer of the EOS 20D digital SLR, wedding and portrait photographers have a cost effective solution for capturing both posed and candid event photographs.

DIWA Platinum Medal Award

DIWA Award for Canon 20D


DIWA members from Europe and USA have chosen the Canon EOS 20D as the best "Digital System Camera" in 2004, for which it receives the DIWA Platinum Award in its category. The EOS 20D took a giant leap in the never-ending process of technological development, improvement and perfection, elevating image quality and camera performance to a new standard. The robust camera body has the same renowned ergonomic EOS design as its professional siblings, perfected by Canon over decades of camera development. Canon's own 8 Megapixel CMOS image sensor delivers low-noise images over a large range of sensitivities. Sparked by an ultra-fast DIGIC II image processor, the EOS 20D overtakes many of its rivals in terms of shooting speed, processing speed, storing speed and camera response. Professionals and serious photo enthusiasts alike embrace the camera for its outstanding value for money.
