The Canon EOS 20D is an 8.2-megapixel semi-professional digital single-lens reflex camera, initially announced on 19 August 2004 at a recommended retail price of US$1,499. It is the successor of the EOS 10D, and was succeeded by the EOS 30D in August 2006. It accepts EF and EF-S lenses and uses an APS-C sized image sensor.
The 20D features a new sensor and a greater megapixel count (8.2 megapixels instead of 6.3) and retains the Canon 1.6x crop factor. The 20D supports USB 2.0. The 20D has a larger buffer and can shoot more frames per second. It also uses the E-TTL II flash metering system and uses the DIGIC II image processor.
The EOS 20D (with appropriate firmware updates) can also accept the Canon Wireless File Transmitter WFT-E1/E1A for fast file transfer to a remote file server, either through an ethernet cable or a Wi-Fi network.
The Canon EOS 20D has several resolution settings:
The 20D is the first Canon prosumer camera to use the EF-S lens mount; the first Canon EOS camera to use the mount was the 300D (the Digital Rebel in North America).
Canon released the EOS 20Da on 14 February 2005 in Japan. It is a variant of the 20D designed for astrophotography. On 1 June 2005 Canon announced that the 20Da would be made available worldwide.
