  • Page 3: Overview

    Highlight Tone Priority improves exposures in difficult lighting conditions. The EOS 40D is really fast, too. It fires those 10.1 megapixel, 14-bit files at 6.5 frames per second, shooting continuously with 75 shot bursts of Large/Fine JPEGs or 17 RAW images.

  • Page 4: Summary Of New And Improved Features

    II. SUMMARY OF NEW AND IMPROVED FEATURES • 10.1-megapixel CMOS sensor (APS-C size) with improved microlenses for superior image quality • DIGIC III with 4-channel reading for fine image detail, natural colors and faster process- ing and writing • 14 bit A/D conversion yields finer gradation, more colors •...

    1st-curtain shutter, and much more. * Standard output sensitivity. Recommended exposure index. Although the EOS 40D’s single-piece CMOS sensor is based on the Canon EOS Digital Rebel XTi’s sensor design and manufacturing technology, new processes were incorporated in the CMOS semiconductor fabrication and microlens-forming process. By improving light-collecting efficiency, the same ISO range and low noise (S/N ratio) as that of the EOS 30D were attained even though the pixels on the 30D are larger.

    C.Fn II-2. Highlight Tone Priority (ISO range 200-1600*), makes gradation finer from grays to highlights, reducing the likelihood of blown high values. This feature, too, first appeared on the EOS-1D Mark III. It is set on the EOS 40D via C.Fn II-3. * Standard output sensitivity. Recommended exposure index.

  • Page 7: Auto Iso

    The Picture Style function has the same specifications as Picture Style Screen those of the EOS 30D, but the EOS 40D is also compatible with Canon’s new Picture Style Editor software, which allows even more control over image quality (see page 26 for details).

  • Page 8: High Iso Noise Reduction

    100-800,* 1 stop greater on the high end than with the EOS 30D. * Standard output sensitivity. Recommended exposure index. Long exposure noise reduction is equal on the EOS 40D and 30D cameras. [Off], [Auto], High ISO Noise Reduction or [On/always applied] can be selected.

  • Page 9: White Balance

    EOS Integrated As in the examples of the EOS-1D Mark III and the EOS Digital Rebel XTi, the EOS 40D Cleaning System incorporates the highly practical EOS Integrated Cleaning System to help prevent dust generation and adhesion of dust to the low-pass filter.

    However, there are slight differences such as the shutter operation sequence for [Clean now]. For the EOS-1D Mark III, it is: Cleaning operation -> Shutter cocking -> Cleaning operation -> Shutter cocking -> Cleaning operation. In the EOS 40D, it is: Cleaning opera- tion -> Shutter release -> Cleaning operation.

  • Page 12: Drive

    The algorithm for automatic AF point selection in the EOS 40D is the same as the EOS 30D's. However, because all the AF points are now cross-type sensors, subject detection is improved, making the AI SERVO AF subject-tracking performance better. Also, in the One-Shot AF mode, the probability of capturing the subject as intended is increased.

  • Page 13: Shutter

    2-sec. self-timer. Shutter While it is based on the EOS 30D's mechanical shutter unit, the shutter of the EOS 40D is now more reliable with a contactless switch instead of a contact switch for running the 1st and 2nd curtains.

  • Page 14: Live View Function

    View Function. The EOS 40D has it as well, along with some useful improvements. In addition to the Live View Function found in the EOS-1D Mark III, the EOS 40D enables "AF during Live View Function" and "Silent shooting." (Note: Live View Function is only possible with the Creative Zone modes.)
  • Page 15 operation. It synchronizes with the mechanical 2nd-curtain shutter to obtain a slit exposure. (Note that with CMOS, it is difficult to have an electronic 2nd-curtain shutter. Therefore, only the 1st-curtain shutter is electronic.) As a result of the electronic 1st-curtain shutter, the [Silent shoot] Modes 1 and 2 make the shutter-release time lag shorter and reduce shutter-cocking noise.

    LCD Monitor The EOS 40D has a 3.0-in. TFT liquid-crystal color LCD monitor with approximately 230,000 pixels and a wide, 140º viewing angle, both horizontally and vertically. Note that the viewing angle has actually been reduced from 170º on the EOS 30D to improve ease of viewing outdoors, and that the screen’s brightness level has been increased for...

    Live View Function, 3.0-in. LCD monitor with wider color gamut and enhanced information display (ISO always displayed, LCD monitor also used to display settings of shooting functions) all make the EOS 40D easier to use, more flexible and more controllable in an unlimited range of conditions and circumstances.

    Camera Direct Printing Two useful additions have been made to printing direct Printing Effects from the camera. First, a preview display shows effects such as B/W, Vivid, Brightness correction, Hue, and Adjust levels before printing. The feature is not enabled for face brightener or red-eye correction.
