Control Enumeration
With the foregoing as background, here's a step-by-step description of the 1Ds Mark II's various controls and their operation:
Shutter Button: Located on the top of the camera body, sloping down toward the front panel, this button sets focus and/or exposure when pressed halfway. A full press fires the shutter.
Depth of Field Preview Button: Hidden on the lower right side of the lens mount (when holding the camera from behind), this button previews the depth of field in the viewfinder. Pressing the button stops the lens down to the selected aperture, letting you visually check the depth of field.
Lens Release Button: On the left side of the camera's front panel, this semicircular button releases a latch so the lens can be removed with a turn to the right.
FE Lock / Multi-Spot Metering Button ("FEL"): Situated on the top panel of the camera, just behind the Shutter button, this button controls the flash exposure lock and Multi-Metering functions, just like its vertical grip counterpart. Pressing the button when a Canon Speedlight is in use locks the exposure based on a test flash. In Multi-Spot Metering mode (with the flash off), this button selects up to eight metering points for exposure calculation.
Main Dial: To the right of the FE Lock / Multi-Spot Metering button, this dial controls a variety of camera functions when turned while pressing a control button. Depending on the exposure mode, turning the dial on its own adjusts some of the functions listed on the top LCD panel, such as aperture or shutter speed. In Program AE mode, turning this dial cycles through a range of equivalent exposure settings.
LCD Panel Illumination Button: Behind and to the left of the FE Lock / Multi-Spot Metering button, this button activates an electroluminescent blue background illumination for both the rear and top status LCD panels. You can turn off the illumination by pressing the button a second time. Pressing the button once leaves the light on for six seconds.
Exposure Compensation / Aperture Button: To the right of the LCD Panel Illumination button, this button controls the exposure compensation in conjunction with the Main dial (in all exposure modes except Manual). Pressing the button blanks all the top-panel LCD readouts except the exposure compensation indicator, and connects the Main dial to the exposure compensation adjustment. Pressing the button again or half-pressing the Shutter button registers the exposure compensation setting you've selected, and puts the camera back in shooting mode. In Manual mode, pressing this button while turning the Main dial controls the aperture setting.
Metering Mode / Flash Exposure Compensation Button: The first button on the far left side of the top panel (when looking from the back), this button changes the current metering mode when pressed while turning the Main dial, cycling through Evaluative, Partial, Spot, Center-Weighted, and AF Point-Linked Spot metering modes. When pressed while turning the Quick Control dial on the back panel, the flash exposure compensation is adjusted from -3 to +3 exposure values (EV) in one-third-step increments. (Note that this only applies to Canon dedicated Speedlights.) Pressing this button in conjunction with the Shooting Mode (MODE) button while turning the Main dial adjusts the camera's Drive mode, cycling through Single Frame, Continuous, 10-Second Self-Timer, and Two-Second Self-Timer modes. Finally, pressing this button in conjunction with the AF Mode button while turning the Main dial sets the ISO sensitivity.
AF Mode Button: The next button on the left, just in front of the Metering Mode / Flash Exposure Compensation button, this button sets the autofocus mode when pressed while turning the Main dial, cycling between One-Shot AF and AI Servo AF (which focuses continuously to track moving subjects). Pressing this button while holding down the Metering Mode / Flash Exposure Compensation button and turning the Main dial adjusts the ISO setting. Additionally, holding down this button while pressing the Shooting Mode button and turning the Main dial activates the Auto Exposure Bracketing mode and sets the amount of exposure variation.
Shooting Mode Button: The last button on the left side of the top panel, this button sets the camera's exposure mode when held down while turning the Main dial, cycling through the following modes:
- Program AE: The camera selects the best shutter speed and aperture settings, while the user chooses all other exposure variables. Turning the Main dial in this mode adjusts the exposure program through a range of equivalent exposure settings, using different combinations of aperture and shutter speed.
- Aperture Priority: In this mode, the user chooses the lens aperture setting, while the camera selects the best corresponding shutter speed.
- Manual: The user controls all aspects of the exposure, including both shutter speed and aperture.
- Shutter Priority: As the opposite of Aperture Priority mode, this mode allows the user to select the shutter speed, while the camera chooses the best corresponding aperture setting.
- Bulb: Extends the Manual exposure mode by allowing unlimited-length shutter times. (Limited by battery life to three hours, but on a practical basis to a couple of minutes or less, due to sensor noise.)
When pressed in conjunction with the AF Mode button while turning the Main dial, this button activates the Auto Exposure Bracketing mode and adjusts the amount of exposure variation. Pressing this button while holding down the Metering Mode / Flash Exposure Compensation button adjusts the camera's Drive mode, cycling through Single Frame, Continuous, 10-Second Self-Timer, and Two-Second Self-Timer modes.
Diopter Adjustment Dial: Located on the camera's back panel, to the left of the viewfinder, this dial adjusts the optical viewfinder display to accommodate eyeglass wearers.
Eyepiece Shutter Lever: On the opposite side of the viewfinder, this lever opens and closes a small shutter inside the eyepiece, which prevents incident light from affecting the exposure when the camera is mounted on a tripod. (Normally, the photographer's eye prevents ambient light from entering the viewfinder eyepiece.)
Assist / White Balance Correction Button: Directly to the right of the Eyepiece Shutter lever, this button registers the selected AF point when pressed in conjunction with the Flash Exposure Lock button. Pressing this button with the AF Point Selection button switches between the normal AF mode and the registered AF point. Very handy for quickly switching between a specific AF point and normal multi-area AF operation. The operation of this control may be modified somewhat through Custom Function menu 18.
When pressing the WB button on the rear panel and this button simultaneously, you can adjust the white balance by altering the amount of blue, amber, magenta, or green, using the Main and Command dials.
AE Lock ("*") / Reduce Button: To the right of the Assist button, this button locks the exposure when pressed. (The AE Lock is canceled six seconds later, or when a shot is taken, whichever comes first.)
In Playback mode, this button reduces the magnified image display when pressed while holding down the Format / Magnify button.
AF Point Selection / Magnify Button: Directly to the right of the AE Lock button, this button selects one of the 45 AF points when pressed while turning either the Quick Control or Main dials. (The Quick Control dial selects vertically, while the Main dial selects horizontally.) Pressing this button simultaneously with the Assist button switches between the normal AF mode and the registered AF point.
In Playback mode, this button magnifies the displayed image, as much as 10x, when pressed while holding down the Format / Magnify button.
Quick Control Dial Switch: In the center of the back panel, above the Quick Control dial, this switch turns the dial on or off, as a precaution against changes being made if it is accidentally turned.
Quick Control Dial: The large dial in the center of the back panel, this dial controls a variety of camera settings when turned while pressing control buttons. During image playback, turning this dial scrolls through captured images, and moves up and down in a zoomed image (while the main dial handles left and right movement), and it is a primary user interface element for navigating the LCD menu system.
Main Switch: Directly below the Quick Control dial, this switch turns the camera on or off. In its third position (marked with a little speaker icon), the beeper is enabled, to signal when focus is achieved.
Memory Card Slot Release Latch: Located at the bottom left corner of the dual-slot memory card compartment, this switch unlocks the compartment door, allowing you to remove the memory cards.
Protect / Sound Recording Button: The first button in a series lining the left side of the LCD monitor, this button assigns or removes write protection for selected files during image playback. Also in Playback mode, this button allows you to record as long as 30 seconds of audio to attach to an image file, by holding down the button for two seconds. (Very handy for pros needing to keep track of what's recorded in various shots.)
Menu Button: Directly below the Protect / Sound Recording button, this button displays the LCD menu system. Unlike most digital cameras, you must press and hold this button and use the Quick dial to move between the different Menu tabs. Only when you release this button are you able to press and hold the select button to scroll through each menu item.
Select Button: The third button in the series on the left side of the LCD monitor, this button selects menu settings while in the LCD menu system. Like the Menu button, it must be held down as you scroll through the options. Releasing it selects the option and moves you to the next step in selecting (a fly out menu or selection buttons, for example. You must press the button again to make further selections with the Quick dial as you move through the settings. It can be confusing at first, but will seem plenty natural after a short time. When playing back images, this button lets you scroll through captured frames when pressed while turning the Quick Control dial.
Display / White Balance Bracketing Button: Just below the Select button, this button controls the LCD display mode when playing back images. A full press of the button turns the display on or off. Holding down the button while turning the Quick Control dial cycles through the image playback display modes, including Info (with histogram), Single Image Display, Four-Image Display, Nine-Image Display, and Storage (which allows users to create new image storage folders). In Record mode, pressing this button in conjunction with the White Balance button activates the White Balance Bracketing mode, letting you adjust the parameters before shooting.
Format / Magnify Button: The last button in the series, this button lets you format the memory card when pressed in Record mode. In Playback mode, you can enlarge the captured image by holding down this button and pressing the Reduce or Magnify buttons mentioned above.
Erase Button: Located below the LCD monitor as the first button in a series, this button erases selected images or folders.
Image Size Selection Button: To the right of the Erase button, this button cycles through the file resolution settings when pressed while turning the Quick Control button. Pressing and holding this button with the White Balance button for two seconds returns the camera's settings to their defaults.
White Balance Button: Directly to the right of the Quality button, this button cycles through the available White Balance settings when pressed while turning the Quick Control dial. When held down in conjunction with the Quality button, this button resets the camera settings to their defaults. Holding this button while pressing the Display button activates the White Balance Bracketing mode.
Vertical Grip Operation On/Off Switch: Located on the right side of the camera (when looking from the back) and near the cluster of vertical grip controls, this switch turns those controls on or off. Disabling the controls prevents accidental activation when shooting with the camera in a normal horizontal orientation.
Vertical Grip Shutter Button: Directly below the primary Shutter button, but on the bottom panel of the camera, this button performs the same shutter functions when shooting with the camera held vertically. It may be a little more sensitive in our experience, especially when shooting in High or Low speed Continuous modes, more frequently firing off two or three shots than the main shutter button.
Vertical Grip Main Dial: Like the Main dial on top of the camera, this dial controls a variety of camera settings when rotated while holding down a control button. Located just behind the Vertical Grip Shutter button, this dial controls several functions on the top LCD panel when turned by itself, such as aperture or shutter speed, depending on the exposure mode. When turned while in Program AE mode, the dial cycles through a range of equivalent exposures.
Vertical Grip FE Lock / Multi-Spot Metering Button ("FEL"): Just behind the Vertical Grip Main dial, this button locks the exposure when an external flash is used. Like the main FE Lock button, when no flash is in use, this button sets the metering points for the Multi-Spot Metering mode, which averages the exposure from as many as eight separate readings.
Vertical Grip Assist / White Balance Correction Button: Just like the Assist button at the top of the back panel, this button (located in the lower right corner of the back panel) registers the AF point when pressed in conjunction with the Flash Exposure Lock button. It also switches between the normal AF setting and the registered point when pressed simultaneously with the AF Point Selection button.
When pressed with the WB button, this button lets you adjust the amount of blue, amber, magenta, and green in the color balance.
Vertical Grip AE Lock / Reduce Button: To the right of and below the Vertical Grip Assist button, this button locks the exposure for a maximum of six seconds when pressed once.
In Playback mode, this button reduces the enlarged playback view when pressed while holding down the Magnify button.
Vertical Grip AF Point Selection / Magnify Button: The final vertical grip control in the lower right corner of the back panel, this button performs the same functions as its main counterpart, allowing you to select an AF point for use by holding down the button and turning the Quick Control or Main dial. Pressing this button with the Assist button selects between the normal AF mode and the registered AF point.
In Playback mode, this button enlarges the review display when pressed while holding down the Magnify button.
Battery Compartment Release Button: Situated on the left side of the camera, when looking from the back, this button must be pressed to fully release the battery after turning the Battery Release Handle.
Battery Release Handle: Also on the left, centered on the battery itself, must be turned to the left, then the Battery Compartment Release Button must be depressed.
