Description: Features
The EOS 40D SLR Digital Camera is a superb choice for advanced amateur photographers and entry-level professionals. It incorporates an enhanced, 10.1-megapixel CMOS imaging sensor with the proprietary and super-efficient DIGIC III image processor together with a completely redesigned auto-focus sensor.

Ideal for shooting - and actually capturing - speed-sensitive subjects such as wildlife-nature shots as well as a wide variety of action and sports scenes, the combination of latest processor, DDR SDRAM high-speed memory, four-channel-per-line sensor readout, and two separate motors for shutter and mirror operation provides a fast, 6.5 frame-per-second (fps) continuous shooting capability, a top shutter speed of 1/8000 seconds, a fast 0.15-second initial start-up, and nearly instantaneous shutter response. Even with all of this speed, the EOS 40D Digital SLR provides impressive image quality using a 10.1-megapixel CMOS APS-C size image sensor that utilizes large microlenses over each pixel to reduce noise and expand sensitivity up to ISO 3200. Furthermore, the 14-bit Analog-to-Digital (A/D) conversion process enables the camera to recognize 16, 384 colors per pixel for finer and more accurate gradations of tones and colors. Proprietary DIGIC III image processing engine then ensures that the fine details and natural colors of the images are optimally recorded and, as an added bonus, is also responsible for its efficient energy consumption.

The Large three-inch 230, 000-pixel LCD screen of the EOS 40D provides broad color gamut and a viewing angle of 140-degree perspective in all directions to increase viewing ease in conditions such as bright sunlight. An added advantage of the large display is the ability to use a larger font size for text, making it easier to read setting and menu options. More significantly, the Live View function uses the LCD display to provide an expanded and exceedingly convenient set of shooting options. By permitting the framing and capturing of subjects using the camera's LCD screen instead of the viewfinder, the shooter gains a 100 percent field view to more easily achieve the desired composition, and an added Custom Function allows auto-focus during Live View, and provides the user with the ability to magnify the image by five or ten times in order to ensure optimal focus. Live View is at its best during tripod shooting - particularly for close-up photography where precise focusing is imperative. The EOS 40D is also a boon to more traditional shooters as well with an upgraded viewfinder that has an optical magnification of 0.95x, a viewing angle of 264 degrees and an eye point of 22mm.

The enhanced durability of the EOS 40D is attributed to its magnesium alloy exterior with upgraded dust and weather resistant construction, particularly around the camera's connection ports, battery compartment and memory card door. Plus the camera incorporates an extremely durable shutter that has been rated up to 100, 000 cycles, The camera also helps to secure it's data from the most common cause of data corruption problems; Should the user inadvertently open the CompactFlash card door while the camera is writing to the card, a warning will pop up on the LCD screen and an "alarm" will sound, but the image(s) will continue writing to the memory card without interruption.
