Features & Controls (cont.)





Canon EOS 40D



The EOS 40D has a new, enlarged & optimized pentaprism and a larger diameter eyepiece lens. The viewfinder looks bigger with less vignetting. To make the viewfinder clearer and easier to see, the magnification is 0.95x, the angle of view is 26.4°, and the eyepoint is 22mm. By comparison, the EOS 30D's viewfinder gave 0.9x magnification, a 25.1° angle of view, and a 20mm eyepoint. On both cameras, the coverage is 95% and the dioptric adjustment is -3 to +1.

The information display inside the finder has been enhanced in several ways over the 30D: the ISO is always displayed, even when Auto ISO is set; a Black and White setting alert has been added; and the maximum burst possible is displayed in two digits instead of one. The LCD monitor can also be used to display the settings of the shooting functions.

The information presented in the viewfinder includes:AE lock, flash-ready, high-speed sync, flash exposure compensation, shutter speed, aperture, exposure level indicator, monochrome shooting, ISO, white balance correction, max. burst, focus confirmation. The focusing screen displays the spot metering circle and AF points.

The EOS 40D has a 3-inch 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 the same reason. Also, the color gamut has been broadened. Brightness is adjustable to any of seven levels. In all, the LCD monitor is easier to use and more accurate than the one on the 30D.

Controls on the back of the 40D, beginning at the upper left, are the Menu button and to the right, the Print/Share button. Dropping down below the LCD you can see the Playback button then moving right, the Erase button, the Jump button, the Info/Trimming button, the Picture Style selector and finally the On/Off switch.

Moving up again to the right of the Eyecup you can see the Diopter adjustment knob. If we move to the upper right of the camera you can see the AF-On/AF Start button, the AE Lock/FE Lock and furthest to the right we see the AF Point selector/ Enlarge button.Traveling down and to the right of the LCD you find the large Quick Control Dial that has the Set button in the center.

The monochrome data LCD displays all major camera settings such as shutter speed and aperture values, exposure mode, ISO speed, focus mode, metering mode, drive mode, custom function, flash exposure compensation, exposure bracketing, exposure compensation, self timer and battery status. The data LCD can be illuminated with an amber backlight by pressing the light bulb icon on the top of the camera.

(The actual image size, number of possible shots and maximum burst will vary depending on the subject, shooting mode, ISO speed, Picture Style etc.)

I/O ports are on the left side of the 40D, below the Mode dial. Top right we see the video out terminal which uses the provided video cable to connect to a TV (NTSC or PAL). Below that is the USB connector. Moving to the top left we can see the PC terminal and below that is the Remote control terminal (N3 type). When not in use, the IO connections are protected by a flexible terminal cover.

Additionally, the 40D has an extension system terminal on the bottom of the camera which is used by the optional Wireless File Transmitter (WFT-E3A).



PIXMA Pro 9500



In addition to its standard PictBridge features, which are compatible with most PictBridge-compliant printers, the EOS 40D supports additional direct printing features exclusively when the camera is connected to the Canon PIXMA Pro9500 desktop photo printer - these features include the following:

  • Full support for Picture Style settings: Images are printed according to the photographer's preferences for sharpening, contrast, saturation and color tone, as well as monochrome and other special effects.

  • Fine adjustment of other image quality settings such as color balance, color space (including Adobe RGB), overall brightness, face brightness and microcontrast levels as well as a red-eye correction function.

  • Expanded paper selection, including a range of fine art paper stocks available in a variety of sizes up to 13" x 19".

Two useful new additions have been made to printing direct 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. Then, tilt angle correction adjusts the angle of images shot with a tilt to print horizontally. With the trimming screen, turn the Quick Control Dial to tilt the image up to ±10 degrees in 0.5° increments. As with the EOS-1D Mark III, RAW, sRAW and JPEG printing and Red-Eye 1 are provided. Camera Direct Printing is now compatible only with PictBridge. Bubble Jet Direct and CP Direct are not supported. Print order (DPOF) and direct image transfer are the same as with EOS 30D.





Canon EOS 40D



The battery system is the same as the EOS 30D's and includes the Battery Pack BP-511A. With a fully-charged battery, the number of possible shots without flash use is about 1100 at 73°F/23°C. With 50% flash use, it is about 800 shots. The date/time backup battery is a lithium battery CR2016 installed in the battery compartment.

The supplied CG-580 compact charger requires approx. 100 minutes to charge a fully a depleted BP-511A battery pack. An LED on the charger indicates the charge level. Other compatible batteries are: BP-511, BP-511A, BP-514 or BP-512.

The BG-E2N is a high-capacity battery grip dedicated to the EOS 40D. It was developed to enable high-volume shooting and easier vertical shooting. It can accommodate the BP-511A as well as AA-size batteries. Basically, the BG-E2N is the same as Battery Grip BG-E2 for EOS 30D. However, the battery compartment cover now has sealing material to make it more resistant to dust and water than the BG-E2.

The WFT-E3A is a dedicated EOS 40D accessory (similar to the WFT-E2A the wireless file transmitter unit for the EOS-1D Mark III) offering wireless or wired network functions (via FTP, PTP, or HTTP) and support for USB peripherals (specifically, external storage devices and GPS units). There are 2 main differences from WFT-E2A: inclusion of controls for vertical shooting and inclusion of the unit's own power supply. Compared with the WFT-E1A, communication speed is 1.5x faster (wireless) and 3x faster (wired).
