From the Manufacturer
Building on the success of Canon's perennially popular "prosumer" EOS 20D and 30D models, the EOS 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 EOS 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.
From the camera's newly enhanced, 10.1-megapixel CMOS imaging sensor (designed and manufactured by Canon) and its proprietary and super-efficient DIGIC III image processor, to its completely redesigned autofocus sensor and fast, 6.5 frame-per-second (fps) continuous shooting capability (for bursts of up to 75 Large/Fine JPEGs or 17 RAW images), the EOS 40D SLR puts the fun in functionality and makes serious photo business a positive pleasure.
Canon EOS 40D Highlights
Canon extends its "ease-of-reading" policy to the EOS 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.
Improved Image Quality Although it is based on the image sensor used in the EOS Digital Rebel XTi, the EOS 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 EOS 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 EOS 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 EOS 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 EOS 40D also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced earlier this year with the EOS-1D Mark III Professional Digital SLR.
DIGIC III DIGIC III is the latest generation of Canon's proprietary image processing engine. DIGIC III technology ensures that the fine details and natural colors of the images are optimally recorded and, as an added bonus, is also responsible for the EOS 40D SLR's high-speed performance, faster signal processing, and even its efficient energy consumption.
sRAW In addition to retaining the RAW image capture capabilities of its predecessors, the EOS 40D SLR now offers a more manageable "sRAW" recording format. In sRAW mode, the number of pixels is reduced to one-fourth that of a standard RAW image and the file size is cut in half, while retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images.
The Canon EOS 40D Digital SLR retains the same 35-zone metering sensor as its predecessor. Available patterns include Evaluative metering, which is linked to all AF points and is set automatically in the Basic Zone modes, Centerweighted average metering, Partial metering, and Spot metering, covering approximately 9 percent or 3.8 percent of the viewfinder at center, respectively. The camera's E-TTL II autoflash and 12 exposure control modes (11 AE modes plus manual) are also unchanged from the EOS 30D SLR model. However, as a result of consumer input, Canon has added three Custom exposure modes. As an added convenience, particularly for wireless flash operations, users can adjust the flash settings of the Canon Speedlite 580EX II directly from the camera.
The Canon EOS 40D camera offers ISO speeds from ISO 100 to ISO 1600 in 1/3-stop increments. Users can also opt for a high-speed setting of ISO 3200. For the first time in any EOS camera, the 40D model offers Auto ISO capability in Creative Zone exposure modes. This valuable new feature adjusts the ISO speed to the optimal setting based on low light or shaky shooting conditions. Additionally, the EOS 40D provides full-time display of the active ISO speed setting, both in the viewfinder as well as on the top LCD data panel.
The Canon EOS 40D Digital SLR is also the first camera in its class to offer two interchangeable focusing screens in addition to the standard precision matte screen. Users can opt for a grid-type focus screen that makes it easier to verify horizontal or vertical alignment while determining image composition, as well as the Super-Precision Matte focusing screen that makes it easier to grasp the "sweet spot" of manual focusing when using a lens with a maximum aperture of f2.8 or faster.
EOS Integrated Cleaning System First introduced on the EOS Digital Rebel XTi camera, the EOS Integrated Cleaning System is a prime example of trickle-up technology and is now becoming a standard feature on all new EOS Digital SLRs. The camera's Self-Cleaning Sensor Unit uses ultrasonic vibrations to literally shake dust particles off of the low-pass filter in front of the sensor each time the camera is powered up or shut down. Users also have the option of engaging the "clean now" function at will or bypassing it altogether. Additionally, the EOS 40D SLR's manual sensor cleaning function raises the mirror and allows users to clean dust that has stuck to the low-pass filter. Dust that has been shaken or blown loose is then trapped by adhesive at the base of the sensor unit housing, preventing the problematic particles from reattaching themselves to the filter when the camera moves. The second part of the cleaning system is a software solution that maps the location of any spots that may remain on the sensor. The mapped information is saved as Dust Delete Data and attached to the image file. Subsequently, the offending dust information is subtracted from the final image during post processing with a compatible personal computer, using the supplied Digital Photo Professional software.
Improved Software Among the most valuable features of the Canon EOS 40D Digital SLR is its compatibility with Canon's Picture Style Editor (PSE) 1.0 software. With PSE, shooters can actually design the look of their photographs by inputting their own preferred style, color, and tone curves. The EOS 40D Digital SLR also ships with the latest versions of Canon's powerful software applications, including Digital Photo Professional 3.1 and EOS Utility 2.1, which now support the camera's Remote Live View and Dust Delete Data functions, as well as incorporating a broad range of additional improvements designed to improve image quality and speed up workflow. Also included are ZoomBrowser EX 5.8 and ImageBrowser 5.8 for easy browsing, viewing, printing, and archiving with compatible computer operating systems, including Microsoft Windows Vista and Windows XP, as well as Mac OS X.
Accessories (Not Included--Must be Purchased Separately) New system accessories for the EOS 40D SLR include the redesigned high-capacity Battery Grip BG-E2N, which facilitates high-volume shooting and easier vertical shooting. Compatible with up to two BP-511A battery packs or a set of six AA-size batteries, the battery grip approximately doubles the number of shots that can be taken, compared with the battery power of the EOS 40D SLR alone. The BG-E2N grip features new sealing material around the battery compartment to better resist water and dust. The new model replaces the original BG-E2 grip and is compatible with the EOS 20D, 30D, and 40D models.
Designed exclusively for the EOS 40D SLR, the new Wireless File Transmitter WFT-E3A permits wireless transfer and back-up, as well as remote control of the camera in Live View mode. It can also be connected to various GPS receivers or Hi-Speed USB 2.0 external storage devices such as convenient flash drives or high-capacity hard drives with much larger storage capacity than the memory cards in the camera for instant back-up as images are captured. Compact and affordable, the WFT-E3A wireless transmitter also doubles as a vertical grip and requires its own BP-511A battery pack in addition to the battery installed in the camera body.
