The mid-range Canon EOS 50D raises image quality and high-speed image processing to next levels with advancements in two key devices: the developed approximately 15.1-million effective pixel CMOS sensor (APS-C size) and the redesigned high-performance DIGIC 4 imaging processor. Along with its enhanced image quality and rich tonal range, the model also utilizes noise-reduction technology to enable high-speed shooting. The EOS 50D supports ISO sensitivity settings from 100 to 3200,*1 which can be expanded to ISO 6400 and 12800 in wide-angle settings, making it the ideal digital SLR camera for a wide range of photographic horizons. Further, because the model accommodates the new CFA 4.1 UDMA CF memory card format for high-speed data transfer, it makes possible a maximum shooting speed of 6.3 frames per second*2 for up to 90*3 consecutive high-resolution images in a burst.

The EOS 50D’s large 3.0-inch clear view LCD monitor features a 160-degree viewing angle, 920,000 dots, and an anti-reflection coating to shield its protective cover from dust. It provides excellent color reproduction that naturally displays images on the finder and greatly improves daylight visibility outdoors. And further contributing to enhanced user friendliness, the Live View function features improved AF (autofocus) performance through the utilization of Face Detection technology. The EOS 50D delivers outstanding basic performance through such features as high-precision all cross type 9-point AF and a high-performance viewfinder employing a glass pentaprism that provides an approximately 0.95x zoom ratio. Other features embody the evolution of digital SLR technology, such as the Auto Lighting Optimizer, which automatically adjusts the brightness and contrast levels of dark images and can now be used with RAW images.

The EOS 50D allows users to smoothly set shooting functions while looking at the LCD monitor with the Quick Settings Screen, or use the Creative Full Auto Mode to take the type of photos they want without prior knowledge of such technical terms as “aperture” and “exposure.” Users are also guaranteed a high degree of reliability with the EOS 50D, given its EOS Integrated Cleaning System sensor dust solution, fluoride-coated Self Cleaning Sensor Unit to suppress dust adherence, high-rigidity magnesium alloy exterior, and durable shutter unit capable of withstanding approximately 100,000 cycles. The EOS 50D is compatible with Canon’s comprehensive range of 60-plus EF interchangeable lenses, including the concurrently announced Image Stabilizer-equipped EF-S18-200mm f/3.5-5.6 lens, featuring an 11x zoom for wide-angle to telephoto coverage.
