Canon EOS 300D

Marketed: September 2003

The Canon EOS 300D, marketed in North America as the EOS Digital Rebel and in Japan as the EOS Kiss Digital, is a 6.3-megapixel entry-level digital SLR camera, initially announced on August 20, 2003 at a price point of $899 without lens, $999 with the "kit" lens. It uses Compact Flash storage. The 300D and Digital Rebel's polycarbonate bodies were originally available in silver color only, whereas the Japanese version was also available in black. Later, black versions of the 300D and Digital Rebel were also released in the US and Europe.

The 300D is often regarded as the little brother of the Canon EOS 10D, which features virtually the same CMOS image sensor and image processing chip. Interestingly, the two cameras also seem to share much of the same in-camera firmware which was demonstrated by hacking back some of the features the 300D missed compared to the 10D. See Hacking below.

The 300D was the first camera to use the Canon EF-S lens mount. Along with the 300D, the EF-S 18-55/3.5-5.6 was introduced as the kit lens, available in a USM version in Japan or as a non-USM version elsewhere.

The introduction of the 300D represents a significant milestone in photography history, as it was the first digital SLR (DSLR) to break the $1000 price barrier.

On 17th February, 2005, Canon announced the 8.0-megapixel EOS 350D (EOS Digital Rebel XT/Kiss N Digital) as the successor to the highly successful 300D.

Because of the 300D's low price point, it has been the subject of much hacking, ranging from homemade white balance cards, flash diffusers and remote shutter controls to unofficial firmware upgrades which enable many of the features of the 10D that were disabled in the 300D, such as ISO 3200, flash exposure (FEC) control, mirror lockup, single-shot autofocus and some of its larger brother's custom functionality. These hacks are not supported by Canon and may invalidate any warranty that the camera may have.

The EOS 300D incorporates a Canon-developed 6.3-megapixel large-area (22.7 x 15.1 mm effective size in a 3:2 aspect ratio) high-resolution CMOS sensor and Canon's exclusive DIGIC Image Processor, which realizes exceeding image-processing speed and precision to fully utilize the performance potential of the sensor. This advanced technology works in concert to realize outstanding image quality and definition, and more natural color reproduction to satisfy the requirements of a broad user base.

The EOS 300D offers advanced shooting features, including a high-speed 7-point wide area autofocus (AF) with focusing points superimposed in the viewfinder, making accurate framing simple; Continuous Shooting at approximately 2.5 frames per second for a burst of up to four shots; and the ability to record JPEG images in one of six formats or as a 12-bit RAW file. Moreover, when a RAW image is captured the EOS 300D simultaneously records and stores a JPEG image (Medium/Fine) within the RAW data, enabling users to view or transmit the compressed JPEG image quickly while also retaining maximum image quality for future editing.

Employing high-density mounting technology and a new chassis and outer-casing configuration with fewer parts, the Canon EOS 300D realizes the smallest and lightest body in the EOS DIGITAL series, measuring just 142 (w) x 99 (h) x 72.4 mm (d) and weighing only 560g. In addition to compact proportions, the camera's design contributes to outstanding usability, concentrating such operating controls as the mode dial and electronic dial on the right-hand side for one-handed operation of most shooting functions. Moreover, for the first time in the series, the EOS 300D incorporates a cross-configured control-button layout that works with a simple "tab" style menu layout to enable easy control of shooting, playback and camera settings without having to scroll.

The EOS 300D is compatible with the PictBridge industry standard for the direct printing of photos from digital cameras. As a result, users can connect the camera directly to any printer enabled for PictBridge, regardless of brand, and output photos (JPEG) without having to use a computer.
