The option of manual sensor cleaning by raising the mirror and using a blower to remove dust is the same as other EOS Digital SLR cameras. AF and New Autofocus Sensor A newly-developed AF sensor with 9 cross- type AF points greatly boosts AF performance, improving both AF detection precision and extreme-defocus subject detection capability. AF sensitivity is now EV -0.5 to EV 18. All AF points work as cross-type points at f/5.6 or better. Both vertical- and horizontal-line sensitive focus detection thus works with any AF point for stable focusing. High-precision AF is attained with fewer AF failures with hard-to-focus subjects. Also, with the sensor pitch reduced from 16m to 14.4m, detection performance is more accurate.

The positioning of the AF points is almost the same as with the EOS 30D's AF sensor. The center AF point has a cross-type AF sensor sensitive to vertical and horizontal lines at f/2.8. This is a first in an EOS camera. Previously, the central sensor for f/2.8 or better was only vertical-line sensitive. Because the f/2.8 sensor is a diagonal, cross-type sensor, it does not obstruct the f/5.6 sensor positioned vertically at the center. The upper center, center, and bottom 3 horizontal-line sensitive sensors are in a 2-line, zigzag configuration. With this double focusing system, inconsistent focusing detection is reduced. By using the 2-line focusing sensors described above, a subject in extreme defocus can be detected and AF control is quick and easy. To attain more stable AF performance than before, the AF unit has more precise AF optics and environmentresistant construction and materials.

Viewfinder Optics The EOS 40D's 22mm eyepoint is the distance Pentaprism at which the viewfinder image area can be viewed without any vignetting of the viewfinder on all 4 edges. Normally, most manufacturers define the eyepoint as the distance at which SI reflective plate Focusing both the viewfinder image area and information screen Main mirror display are visible. The 22mm specification for

the 40D meets both criteria, absence of cut-off as well as visibility of both image and information. The basic configuration of the superimposed display optics is the same as that of the EOS 30D. Interchangeable focusing screens are a new and significant feature of the EOS 40D. The Ef-series focusing screens have been newly developed. 3 screens, the Ef-A Standard Precision Matte, the Ef-D Precision Matte with Grid, and the Ef-S Super Precision Matte are available. All 3 focusing screens have a fresnel lens area and are produced by a new molding method (first used on the EOS-1D Mark IIIs focusing screen Ec-C IV) that provides excellent transfer characteristics. Consequently, even the Standard Precision Matte
Ef-A Standard Precision Matte Ef-D Precision Matte Grid Ef-S Super Precision Matte
screen offers improved performance. The Grid Type screen is particularly convenient for controlling horizontal positioning and as an aid to overall composition. The Super-Precision screen makes it easier to find the sweet spot of focus when using a lens that is faster than f/2.8 and is also effective in difficult, manual focus conditions. The information display inside the finder has been enhanced in several ways: 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. Live View Function One of the major aspects of the EOS-1D Mark III is the inclusion of a fully-functional Live 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.) The EOS 40D's CMOS sensor has an electronic 1st-curtain shutter function, enabling shooting with the mechanical shutter completely open. With Live View Function image displayed, the 40D can shift seamlessly to slit exposures with the electronic 1st-curtain shutter, enabling silent shooting which is not possible with a mechanical 1st-curtain shutter. This electronic 1st-curtain shutter uses a unique high-speed scanning and electronic reset system that accurately mimics the EOS 40D's high-speed mechanical shutter

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. Mode 1 enables continuous shooting at approximately 6 fps and is quieter than ordinary, non-Live View shooting. Continuous shooting is not possible with Mode 2. With Mode 2, shutter cocking does not occur after shutter release, but only when the shutter button is SW-2 OFF. At most, only the shutter curtains make noise, and the shutter sound during the exposure can be limited to the quieter mechanical 2nd-curtain Silent Shooting shutter. Live View Function with the EOS-1D Mark III had the shutter closing after the shutter release before the start of the exposure. This caused shutter-release time lag and shutter-cocking noise. Pressing the AF-ON button pauses the Live View Function; the reflex mirror goes down and the camera executes AF. Letting go of the AF-ON button resumes the Live View Function. With C.Fn III-6, the set AF mode and AF point (automatic selection possible) will be applied during AF while one holds down the AF-ON button.

C.Fn III-6

Note that during this time, there will be no Live View Function image displayed since the reflex mirror will be down. Since no AF points are displayed on the screen with Live View Function, positioning the magnified display's focusing frame at the center and selecting the center AF point for autofocusing is recommended. During AF operation, shutter release is not possible. One must first release the AFON button and wait until the image with Live View Function is displayed, then shoot. With the CMOS sensor's electronic 1st-curtain shutter, shooting is possible while the image with Live View Function is displayed and the mechanical 1st curtain is open. The mechanical 1st curtain need not be closed in order to shoot. This eliminates the mechanical 1st curtain's shutter sound at SW-2 ON which occurs with the EOS-1D Mark III during Live View Function. Silent shooting is therefore possible. As in the case of the EOS-1D Mark III's Live View Function, the exposure is controlled with the mechanical shutter's 1st and 2nd curtains. Set to "Disable" when using a TS-E lens shifted up or down or when using an Extension Tube. If one sets Mode 1 or Mode 2 when using a TS-E lens and a shutter speed of 1/2000 sec. or faster, the small slit created between the electronic 1st-curtain shutter and mechanical 2nd-curtain shutter will be in the same orientation as the optical axis, resulting in underexposure or overexposure.

AF During Live View Function
Similarly, with an Extension Tube and a shutter speed of 1/2000 sec. or higher, the exposure will be uneven at the top and bottom of the image. When using an EX-series Speedlite, the shooting sequence will be the same as the EOS-1D Mark III's Live View Function in either silent shooting Mode

1 or 2. In other words, after pressing 11mm shift up No shift movement the shutter button all the way down to initiate an exposure, the reflex mirror will drop down briefly in order to register the E-TTL II preflash data, then the mirror will be moved out of the optical path during the actual exposure. The Live View Function metering timer is geared mainly for still-life subjects. Live View Function enables the metering timer to be changed to one of 6 settings from 4 sec. to 30 min. Two useful features of Live View Function in the EOS-1D Mark III that appear in the EOS 40D are: Grid Display Live View Function exposure simulation (via C.Fn IV-7) that displays images on the LCD monitor, simulating the shooting exposure used during Live View Function, with the same shutter speed, aperture and other expo sure settings. A grid display that can be selected from the Live View function setting menu During Live View Function,

approximately 170 shots are possible at 73F/23C and Live View exposure simulation approximately 130 shots are (C.Fn IV -7) possible at 32F/0C with flash Battery check used on 50% of the exposures. Picture Style Without using flash, approxiFlash-ready AE lock mately 180 shots can be made at 73F/23C and approximately Shutter speed Aperture 140 shots can be made at Flash exposure compensation 32F/0C (in both cases, a fullycharged Battery Pack BP-511A is used and CIPA testing standards are observed).

Although this series of white papers generally confines itself to new and improved features, the following summary of Live View Function may be useful: Shoot while watching the camera LCD monitor instead of the finder Excellent for precise macro focus No need to stoop or stretch to look in the finder 100% field of view helps control composition Short lag time captures near-instantaneous movements Type: electronic viewfinder with imaging sensor Coverage: approx. 100% vertically and horizontally Frame rate: 30 fps Focusing: Manual focus: magnify the image by 5x or 10x for precise manual focusing Autofocus: with C.Fn III-6-1, press the <AF-ON> button and the reflex mirror will go back down (Live View Function interrupted). The same phase detection AF measurement as during normal shooting is executed. After focus is achieved, let go of the <AF-ON> button and Live View Function will resume. Metering: Real-time evaluative metering with the imaging element AE lock possible Metering range: EV 020 (At 73F/23C, 50mm f/1.4 lens, ISO 100) The active metering time can be changed Exposure confirmation: exposure compensation and AEB simulation possible (C.Fn IV-7-1) Depth-of-field preview: possible with Depth-of-field preview button Magnified view: magnify by 5x or 10x initially at the center of the picture area; focus frame can be moved to any location in the picture area by scrolling with the multicontroller. Grid display: two vertical and two horizontal lattice lines displayable On-screen information display: Focus information: Focus Frame Exposure information: Shutter speed, aperture, AE lock, ISO speed, exposure level Captured image information: Picture Style, histogram, shots remaining Battery check icon Silent shooting: provided (Mode 1 and Mode 2) Possible shooting time: approx. 30 continuous min. (with fully-charged Battery Pack) Shutter-release time lag: (1) With SW-1 ON, time lag from SW-2 ON to the start of the exposure: 0.059 sec. (2) With SW-1 and SW-2 pressed simultaneously, time lag until the start of the exposure: 0.126 sec. Time lag figures above apply with the aperture stopped down by up to 3 stops (reflex mirror operation time excluded). Remote Live View Function: enabled with EOS Utility, outputs Live View Function video for viewing on computer monitor, improves remote shooting by making it possible to check such things as composition, focus, moir, and false colors

Exposure Control

The EOS 40D uses the same 35-zone metering sensor as in the EOS 30D. The metering modes are evaluative, partial (approximately 9% of viewfinder area), spot (approximately 3.8% of viewfinder area), and center-weighted average metering.

Metering Sensor

Previously, during automatic AF point selection and AF point-centered evaluative metering, there was a tendency for slightly excessive compensation. The compensation is now looser so that exposure is more consistent. The E-TTL II autoexposure algorithm of the EOS 40D is the same as the EOS-1D Mark III's E-TTL II autoexposure algorithm. By optimizing the method of using lens distance information, exposure becomes more accurate for highly reflective subjects. With the EOS 30D, the selected metering mode was used to meter the ambient light. This sometimes resulted in inaccurate exposures when the selected metering mode was not evaluative metering. Therefore, as with the EOS-1D Mark III, evaluative metering is now used at all times to meter the ambient light. The EOS 40D uses the same exposure control system as the EOS 30D, with eleven AE modes and manual mode. While based on the EOS 30D's shutter unit, the 40Ds shutter is now more reliable with a contactless switch instead of a contact switch for running the 1st and 2nd curtains. Shutter durability is approximately 100,000 cycles, the same as with the EOS 30Ds shutter. With a fully-charged Battery Pack BP-511A, the shutter supports a bulb exposure as long as about 2.5 hours. Flash A new feature, shared with the EOS-1D Mark III, and a considerable convenience, is that both built-in flash and external Speedlite settings can be set on the EOS 40D from the camera with the menu screen. With external, EX-series Speedlites, this includes Flash mode, sync setting, FEB, flash exposure compensation, E-TTL II, zoom, wireless flash, and clear settings. The EOS 40D can make communication settings as well, such as communication channel, flash group, and flash brightness when the Speedlite 580EX II is used. Also, with the 580EX II attached to the camera, one can set or cancel the Speedlite's Custom Function settings (C.Fn-0 to 13) with the camera. With an EX-series Speedlite other than the 580EX II, the camera cannot be used to set the Speedlite's Custom Functions. The flash unit in the EOS 40D is the same as the unit in the EOS 30D. Its Guide Number is 43/13 at ISO 100 in feet/meters. Flash coverage is effective for focal lengths 18mm and higher, with some limitations based on the size of the lens. If the built-in flash is fired rapidly in succession, the flash firing will be stopped to prevent heat damage to the built-in flash cover and fresnel lens (diffuser). In the case of the EOS Digital Rebel XTi, which has similar specifications, if the built-in flash is fired 20 times successively at 10 sec. or shorter intervals, the firing will be stopped. With the EOS 40D, the flash control is more precise, so the flash stoppage is less likely to occur than with the EOS Digital Rebel XTi.

External flash Custom Function
[Built-in flash func. setting] is a group with [Flash exp. comp], [Shutter sync], and [E-TTL II] (Evaluative/Averaged metering). The latter 2 were previously Custom Functions. [External flash func. setting] now includes [Wireless set.] from the EOS-1D Mark III's [Flash function settings]. This is to enable wireless, multi-Speedlite control. Also, C.Fn items related to the internal flash, such as flash activation, E-TTL II metering method and flash synch Flash Control Built-in Flash Control Wireless Flash Control timing, have been collected in the flash setting menu. LCD Monitor The EOS 40D has a 3.0-in. TFT liquid-crystal color LCD monitor with approximately 230,000 pixels and a wide, 140 viewing angle, both horizontally and vertically. Note that the viewing angle has actually been reduced from 170 on the EOS 30D to improve ease of viewing outdoors, and that the screens brightness level has been increased for the same reason. Also, the color gamut has been broadened. Brightness is adjustable to any of seven levels. The larger monitor size means a larger font size can be used for menu display. In all, the LCD monitor is easier to use and more accurate than before. Design and Construction Like the EOS 30D, the main exterior covers (top, front, and rear) are made of magnesium alloy for light-weight and high strength. The grip portion is integrated with the front cover, enhancing body rigidity further. The body's basic construction is the same as that of the EOS 30D, employing a stainless steel chassis and a mirror box made of highstrength engineering plastic. As with the EOS 30D, the exterior has a high-quality, black satin finish with a non-slip texture. The EOS 40D also has sealing material lining the CF card slot cover and battery compartment cover (which is not found in the 30D) to improve dust- and water-resistance. The EOS 40D has sealing material lining the CF card slot cover and battery compartment cover to improve dust- and water-resistance. The battery compartment covers of both the Battery Grip BG-E2N and the Wireless File Transmitter WFT-E3A have sealing material to improve resistance to dust and water. The configuration of the major components is basically the same as in the EOS 30D, with the exception of the following units which have been added or changed: Self Cleaning Sensor Unit LCD monitor made bigger from 2.5 in. to 3.0 in.

IV. CONVENIENCE

Basic Operation Concepts
While it is grounded in the EOS 30D's basic operation concepts, the EOS 40D has improvements that make it easier to use. The shooting buttons above the LCD panel have been reassigned; an AF Start button (AF-ON) is provided (as with the EOS-1D Mark III), and the Picture Style selection button is new. As much as possible, though, the operation method, screen design, and specifications were kept the same as those of the EOS-1D Mark III. Shooting functions are now assigned to 3 buttons above the LCD panel. Through these buttons, the most frequentlychanged settings are now accessible near the Main Dial. As with the EOS-1D Mark III, one uses the Main Dial to change ISO speed, AF mode, and metering mode. The Quick Control Dial is used to change flash exposure compensation, drive mode, and white balance. The menu operation method is also now the same as with the EOS-1D Mark III. Canon is making camera operation methods as uniform as possible throughout their professional and advanced amateur ranges. The new interchangeable focusing screens, 2-sec. self-timer, sRAW file format, My Menu, camera setting registration, 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 Setting Display

The EOS 40D has a shooting function setting display on the LCD monitor. Setting details can be verified in the large text display. This feature is also effective when the upper display panel is difficult to see, such as when it is in an elevated position during tripod use.

Because the EOS 40D does not have a display-off sensor, press the INFO. button to turn on/off the INFO display. If auto power off is [Off] and the camera is left idle, the LCD monitor will turn off automatically after 30 min., but the camera power does not turn off. Menu Setting Display As in the case of the EOS-1D Mark III, one turns the Main Dial to select the menu tab and turns the Quick Control Dial to select menu options. The Multi-controller can also be used for menu operations. The menus are: Shooting, Playback, Set-up, Custom Function and My Menu. They are now available in 18 different languages with the addition of Greek, Polish and Portuguese. Playback Display Changes in playback display follow features introduced with the EOS-1D Mark III. During single-image playback, pressing the <INFO.> button switches the shooting information screen in the sequence shown here. One can also set the menu option to display the overexposed highlight warning and now, as well, the AF point that achieved focus. There are 2 types of single-image full display and, also new, 2 types of shooting information display.

V. SOFTWARE

Consistent with Canons practice of providing a complete software package at no additional expense to purchasers of its Digital SLR cameras, the EOS Digital Solution Disk Ver.15 is included with the EOS 40D camera. It includes Picture Style Editor Ver.1.0 a new program discussed here. The other software on the disk has been upgraded for EOS 40D compatibility, including RAW files. EOS Utility Ver.2.1 allows folder monitoring with the Wireless File Transmitter WFT-E3A and link-ups with Picture Style Editor. Picture Style was first included as part of EOS Digital in the fall of 2005. Since then, it has become a standard feature in EOS Digital and will be incorporated into the entire current EOS product range in the latter half of 2007. These features, namely: the standardization of image characteristics across all EOS Digital models optimized support for photographic expression according to purpose support for RAW images shot on older models in DPP support for web downloading of Picture Style files according to purpose, have been very well received by users. That said, there have also been calls from advanced users with particularly stringent demands in terms of image processing for even more flexible adjustments that go beyond the preset characteristics supplied by Canon. The Picture Style Editor, as the name suggests, is software that allows users to create their own Picture Style files. To create his or her own Picture Style file, the user selects and loads a sample RAW image and then adjusts the image characteristics based on one of the existing Picture Style settings (Standard, Portrait, Landscape, Neutral or Faithful) except for Monochrome. The created Picture Style file can then be registered in the camera using EOS Utility or used in the DPP or RAW Image Task applications. Settings that can be adjusted in Picture Style Editor: a. Existing Picture Style Detail settings: Color Tone, Color saturation, Contrast and Sharpness adjustments b. Color specification and individual minute adjustments to specified colors: selection of a specific color in the sample image and adjustment of the hue, saturation and Luminosity, as well as minute adjustments to the gamma characteristics (tone curve)
The settings in a. were previously available either on the camera or in EOS Utility, so that the results of any adjustments had PSE Main Window and Tool Palette to be checked later after the picture had actually been taken. With Picture Style Editor, the results of adjustment can be checked in real time. The adjustments in b. are available for the first time (with real time checking) with Picture Style Editor. Up to 100 color points can be selected in the color specifications provided in b. Picture Style Editor ver.1.0 supports RAW images shot only on the EOS 40D. (Future versions will support future EOS models, but no reverse compatibility to older EOS models is planned.) Picture Style Editor has a Preliminary Adjustment window for images that need supplementary adjustment. For images shot with the correct exposure/white balance, there is no need to use preliminary adjustment. The editing window consists of 3 components: Main window: Displays the sample image Navigator window: Displays the position of a magnified image and also displays histograms Tool palette: Provides the adjustment functions Because the adjustments made using the tool palette functions are applied immediately to the sample image shown in the main window, one can check the results in real time.

One can adjust the gamma characteristics of an image using the tone curve. By creating up to 10 adjustment points anywhere along the tone curve, one can freely adjust brightness and contrast. The results of the adjustments are applied to the sample image in the main window in real time.
Adjusting the Gamma Characteristics
One can save all the adjustments one has made with the tool palette as an original Picture Style file (with the.PF2 extension). (Because adjustments made in Picture Style Editor are saved in Picture Style files, they are not saved in the sample image used for the adjustment process.) Adjustments are saved in the save window, which appears when you click the save window display button in the tool palette. When one saves the file, there is a [Disable subsequent editing] checkbox that prevents disclosure of the adjustments made in Picture Style Editor as well as any captions or copyright information. Picture Style files that have been saved with the [Disable subsequent editing] checkbox ticked can be used in cameras and in DPP in the same way as ordinary Picture Style files. However, because they can no longer be opened in Picture Style Editor, one cannot check the adjustments. (We recommend also saving a separate copy of the Picture Style file without the [Disable subsequent editing] checkbox ticked.) Like purpose-made Picture Style files downloaded from the Canon website, saved Picture Style files can be registered and used in cameras and used in the DPP and RAW Image Task applications. (1) Using Picture Style files in cameras: One can use EOS Utility to register a Picture Style file in a camera equipped with the Picture Style function and then apply the file to photographed images. (2) Using Picture Style files with DPP: One can use DPP to apply Picture Style files to any compatible RAW image. (3) Using Picture Style files with RAW Image Task: One can use RAW Image Task to apply Picture Style files to RAW images shot on cameras equipped with the Picture Style function. Picture Style Editor will be included on EOS Digital Solution Disk ver.15. Later this year, Picture Style Editor will be available as a download for all EOS users from the Canon website.

VI. ACCESSORIES AND LENS

Battery Grip BG-E2N
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. In terms of function, the BG-E2N is the same as Battery Grip BG-E2 for EOS 30D, 20D, and 20Da. However, the battery compartment cover now has sealing material to make it more resistant to dust and water than the BG-E2. The power source and method are the same as with the BG-E2. With the introduction of the BG-E2N, the BG-E2 will be discontinued. Therefore, the BG-E2N will be the battery grip for the EOS 30D, 20D, and 20Da henceforth. When the BG-E2N is attached to these cameras, the continuous shooting speed and number of possible shots will be the same as with the BG-E2. Features: (1) The EOS 40D (with BP-511A x 2) enables about twice as many shots to be taken when compared with shooting with one battery (2) Compatible with size-AA batteries (3) Makes vertical shooting as easy as horizontal shooting (4) AC power can be supplied via the ACK-E2 AC power adapter or the CA-PS400 + DR-400 (5) The battery compartment cover has new sealing material to improve resistance to dust and water (6) Hand Strap E1 (sold separately) attachable

Wireless File Transmitter WFT-E3A
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 units own power supply. Compared with the WFT-E1A, communication speed is 1.5x faster (wireless) and 3x faster (wired). For better control of the EOS 40D when shooting with the WFT-E3A attached, the unit provides vertical grip functions. In the same way as when a battery grip such as a BG-E2N, is attached, the WFT-E3A feels well integrated with the camera. The internal antenna offers a wireless range equivalent to that of the WFT-E2A, up to about 492 ft./150m. Like the battery grip, the WFT-E3A attaches to the cameras tripod socket. Wireless and wired LAN function specifications are the same as for WFT-E2A. Note that the camera graphic on the WFT Server screen during HTTP connections has been updated from EOS-1D Mark III to EOS 40D. Requirements for external media or GPS devices that can be connected are the same as for the WFT-E2A. Note that images cannot be copied between media.

New IS Lens

The Canon EF-S 18-55mm f/3.5-5.6 IS is a standard zoom lens specifically for cameras that take EF-S lenses. It was developed in response to market demand for a zoom lens equipped with Image Stabilizer technology at a reasonable price. The advantages of IS in the lens are, first, that each IS system can be designed and optimized for its specific application, yielding a level of performance unattainable by the in-body, shifting sensor technique. Second, one can see the image stabilization effect in the finder. The image is steady; accurate framing is possible; the AF point can be placed precisely, and the photographer can concentrate on the shot and capture the best moment. Panning is also easier and more effective than with the in-body approach. While it is roughly equivalent in weight and size to the EF-S 18-55mm f/3.5-5.6 II/ f/3.5-5.6 II USM, it offers an image stabilization effect equivalent to a shutter speed of 4 stops faster, giving it superb specifications as well as a modest and attractive price.
