Digital Camera Guide

Welcome to the next generation of digital SLR photography-the Canon EOS 40D. The EOS 40D combines Canon's tremendous know-how in both the digital and photographic worlds, creating a camera that not only does everything one would expect of a traditional digital SLR, but one that incorporates staggering leaps forward in technological innovation. With new features like Canon's EOS Integrated Cleaning System, Live View Function, a more powerful DIGIC III Image Processor, plus a 10.1-megapixel CMOS sensor, a 3.0-inch LCD monitor and more, the EOS 40D elevates digital photography to new heights, enhancing the shooting experience, and delivering images one could only expect from a Canon.

Canon's large-area CMOS (complementary metal oxide semiconductor) sensor captures images with exceptional clarity and tonal range, and offers the most pixels in its class. This APS-C size sensor (22.5 x 15.0mm) has the same 3:2 ratio as film cameras, enabling an effective angle of view that is 1.6x the normal EF Lens focal length. 14-bit A/D conversion means fine transitions from light to dark tones, and a significant drop in digital and shadow noise. The EOS 40D has an extensive ISO range (from 100 to 1600, plus ISO 3200* in extended mode) which is selectable in 1/3 stop increments. The EOS 40D's CMOS sensor uses much of the new technology first seen in the EOS-1D Mark III camera. New manufacturing techniques mean each pixel is more sensitive to light, and less area between pixels is wasted on the sensor. The on-chip noise reduction electronics are also entirely new, and combine with the sensor's general design for less digital noise and better high-ISO performance than ever before. This results in larger, clearer, sharper and more detailed photographs right from the start. Download Canon EOS 40D Manual Software Firmware here
