The 40D advances the state-of-the-art for mid-range Digital SLR cameras, making it a natural first choice for advanced amateur photographers and entry-level professionals, and an ideal second body for more established photo pros. Indeed, given the level of feature upgrades and improvements, technological wizardry and user-requested creative controls, the Canon 40D SLR's prosumer appellation may refer more to its accessible price point than to the exceptional quality, clarity and resolution of the images it creates.
Comparison with Canon 30D here :- http://www.pixalo.com/community/phot...pec-17202.html
From the camera's newly enhanced, 10.1-megapixel CMOS imaging sensor and its proprietary and super-efficient DIGIC III image processor, to its completely redesigned autofocus sensor and fast, 6.5 (fps continuous shooting capability (for bursts of up to 75 Large/Fine JPEGs or 17 RAW images), the 40D SLR puts the fun in functionality and makes serious photo business a positive pleasure.
Indeed, at 6.5 fps, no Digital SLR in the 40D mid-range class and price category has so high a continuous shooting capability, making it ideal for shooting - and actually capturing - speed-sensitive outdoor and wild-nature shots as well as a wide variety of action and sports scenes. The speed of the 40D SLR comes from Canon's balanced combination of its latest processor, DIGIC III, DDR SDRAM high-speed memory, four-channel-per-line sensor readout, and two separate motors for shutter and mirror operation.

Display's the Thing
The most easily visible upgrade on the 40D Digital SLR is the camera's larger three-inch LCD screen (compared with the 30D's 2.5-inch monitor). Still, size is only the beginning of the difference between these two cameras' displays.
In order to increase viewing ease in outdoor conditions such as bright sunlight, Canon raised the brightness level of the EOS 40D camera's 230,000-pixel LCD screen, broadened the color gamut and narrowed the viewing angle from
170 degrees to a still wide 140-degree perspective in all directions. An added advantage of the larger-sized display is the ability to use a larger font size for text, making it easier to read setting and menu options on the screen.
The camera's menu is organized in the same tabbed format as the EOS-1D Mark III Digital SLR.
Canon extends its ease-of-reading policy to the 40D SLR's viewfinder as well. The upgraded viewfinder increases optical magnification from 0.90x to 0.95x, expands the viewing angle from 251 degrees to 264 degrees and raises
the eye point from 20mm to 22mm.
Canon design engineers made the 40D SLR's magnesium alloy exterior even more ruggedly dependable than its predecessors with upgraded dust and weather resistant construction, particularly around the camera's
connection ports, battery compartment and single-slot compact flash memory card door. Should the user inadvertently open the compact flash card door while the camera is writing to the card, a warning will pop up on the LCD screen and an open door alarm will sound, but the image(s) will continue writing to the memory card without interruption. The 40D SLR also retains many of the outstanding features of the 30D model,
such as its fast 0.15-second initial start-up, its extremely durable shutter (rated up to 100,000 cycles), its top shutter speed of 1/8000 sec and 1/250 maximum X-sync flash shutter speed setting.
Improved Image Quality
Although it is based on the image sensor used in the Digital Rebel XTi, the 40D Digital SLR's 10.1-megapixel CMOS APS-C size image sensor has been significantly improved thanks to the use of larger microlenses over each pixel to reduce noise and expand sensitivity up to ISO 3200. The 40D retains the model 30D camera's 1.6x focal length conversion factor (compared to full-frame digital image sensors or 35mm film) and is compatible with the full line-up of Canon EF lenses as well as the Company's expanding selection of high-quality,
affordable EF-S lenses created specifically for Canon Digital SLRs with APS-C size image sensors.
Adding to the improved virtuosity of the images captured by the 40D SLR is the camera's 14-bit
Analog-to-Digital (A/D) conversion process. Able to recognize 16,384 colors per channel (four times the
number of colors recognized by the 30D SLR's 12-bit conversion capability), the EOS 40D camera is able to produce images with finer and more accurate gradations of tones and colors. The 40D also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced earlier this year with the 1D Mark III Professional Digital SLR.
