Operation & User Interface
The 5D's user interface is very similar to that of a traditional 35mm SLR film camera, and very similar to that on the EOS-30D and 20D models (with just a few changes that enhance operation somewhat). Current users of Canon EOS SLRs should immediately feel at home. I generally comment on whether or not a camera's controls permit single-handed operation, but in the case of pro-level cameras like the 5D, this is much less of a consideration, since the cameras' bulk and typical shooting scenarios generally demand the use of two hands anyway. I really appreciated the fact that the basic exposure controls are adjustable through the external camera control buttons and dials, greatly reducing your dependence on the rear-panel LCD menu system. The ability to program the Set button for quick changes of menu items such as image review, image quality, and picture style even further reduces reliance on the LCD menu. When you do venture into the menu system, all of the camera's playback and setup options are available in all shooting modes. Overall, I found the 5D's user interface very straightforward and efficient.
Power Switch: Located below the lower right corner of the LCD monitor, this switch turns the camera on or off; switching it to its third position activates the large Quick Dial above and to the right of it for more functions than just navigating the menus.
Mode Dial: Positioned on the left side of the camera's top panel, this dial sets the exposure mode. Exposure modes include Full Automatic, Program AE, Shutter Speed Priority AE, Aperture Priority AE, Manual, Bulb, and Custom modes.
Shutter Button: Located on top of the right hand grip, this button fires the shutter when fully pressed, and sets focus and exposure when halfway pressed in Automatic exposure mode. Halfway pressing this button also puts the camera into an "active" mode, which allows the rear-panel quick control dial to adjust exposure compensation. (You don't need to keep the shutter button half-pressed while working the quick control dial, but you do need to have pressed it within the preceding six seconds.) Pressing the shutter button in any state other than direct printing (for example, when in a menu or reviewing an image) will return the camera almost immediately to readiness for image capture.
Lens Release Button: Located on the front of the camera this semi-circular button located just to the left of the lens mount (as viewed from the back) unlocks the lens from the mount when pressed. The lens can then be removed by rotating it about 45 degrees right to disengage the bayonet mounting flanges.
Depth of Field Preview Button: Positioned on the side of the lens mount housing, just beneath the lens release button, this button lets you preview the depth of field by stopping down the lens aperture to the current setting. (Like most modern SLRs, the 5D normally focuses and meters with the lens wide open, stopping down to the selected aperture just as the picture is being taken.) When an external flash is connected, this button also fires a rapid series of flashes for one second, so that you can check shadows, light balance, and other effects, allowing the flash to be used as a modeling light. (This feature requires use of a Canon dedicated speedlight that supports this capability, such as the model 550EX, or the new 580EX.)
Main Dial: Resting on top of the camera on the right side (as viewed from the back), this ridged wheel adjusts some of the camera's basic settings. When used in conjunction with the appropriate control buttons on the camera's top, the Main dial controls the autofocus mode, metering mode or drive mode. In Aperture-Priority and Shutter-Priority modes, this dial sets the lens aperture or shutter speed. In Manual mode, the dial sets the shutter speed. In Program AE mode, this dial lets the user select from a small range of equivalent exposure settings.
Metering Mode / Flash Exposure Compensation Button: Just off from the top right corner of the small LCD display panel on top of the camera is the shiny black Metering Mode / Flash Exposure Compensation Button. Pressing this button while rotating the Quick Control Dial sets the flash exposure compensation from -2 to +2 in one-third EV increments, for both the built-in flash and any Speedlight EX external flash unit. (Flash exposure compensation cannot be used in Full-Auto mode.) Through the Custom Function menu, you can change the flash exposure compensation adjustment step size to one-half EV increments. Pressing this button while turning the Main dial cycles between the three metering modes: Evaluative, Partial, and Center-Weighted Averaging.
Drive / ISO Speed Button: Located to the left of the Metering Mode / Flash Exposure Compensation button, this button controls the camera's drive mode when pressed while turning the Main dial, cycling through Single Shooting, Continuous Shooting, and Self-Timer drive modes. When pressed while turning the Quick Control dial, this adjusts the ISO setting 100 to 1,600 equivalents in 1/3-stop increments. The 50 and 3,200 settings are only available when the ISO offerings have been expanded through the Custom Functions menu.
AF Mode / White Balance Button: To the left of the Drive / ISO button, this button controls the autofocus and white balance modes. Pressing the button while turning the Main dial sets the autofocus mode to One Shot, AI Focus, or AI Servo. (One Shot is for still subjects, while AI Servo is better for moving subjects, since it causes the camera to focus continuously. AI Focus automatically switches between the two modes.) Pressing this button while turning the Quick Control dial sets the white balance to Auto, Daylight, Shade, Cloudy / Twilight / Sunset, Tungsten, White Fluorescent, Flash, Custom (manual), or Kelvin mode, to match a variety of light sources. The Kelvin temperature setting is adjusted through the settings menu, with values from 2,800 to 10,000 Kelvin in 100K increments. Both functions are only available in the Creative Shooting Zone.
LCD Illuminator Button: Diagonally up and to the left of the AF Mode / White Balance button, this button illuminates the status display window with an orange backlight for six seconds.
Diopter Adjustment Dial: Located outside the top right corner of the viewfinder eyepiece, this dial adjusts the optical viewfinder's focus to accommodate eyeglass wearers, across an unusually wide range of -3 to +1 diopter. (Just barely short of accommodating my own 20:180 vision.) If this much adjustment isn't enough, one of Canon's ten different optional dioptric adjustment lenses can be purchased
Print Button: Just above the top left corner of the LCD monitor, this button enables direct printing to compatible printers.
Menu Button: Topping a column of buttons along the left side of the LCD monitor, this button accesses the 5D's LCD-based operating menu in all modes. Pressing the Menu button a second time cancels the menu display.
Info Button: Just below the Menu button, this button displays the current exposure settings on the LCD screen when pressed. In Playback mode, pressing this button switches between three different formats for the playback display. The options are Single Image Display (with Basic Info), which shows the image number, shutter speed and aperture; Shooting Information, which brings up an information screen that reports the detailed exposure settings that the picture was taken with, and also displays a small histogram which shows the number of pixels having each possible brightness value; and Single Image Display (no Shooting Info) which shows just the image with no overlay. The Info button works regardless of whether you are viewing a single image, multi-image index display, or are using the playback zoom, but the histogram view isn't available when you're zoomed in on an image.
Jump Button: Directly below the Info button, this button allows you to jump 10 frames forward or backward when viewing images in Playback mode. Once pressed, a jump bar appears in the LCD screen, and jumping is controlled by turning the Quick Control Dial forwards or backwards. The Jump button also jumps to the next group in the menu, indicated by color codes on the right side of the display.
Play Button: The final button on the left side of the back panel, this button puts the camera into Playback mode, regardless of the Mode dial setting. (Turning the Quick Control dial in this mode scrolls rapidly through captured images.) Playback mode can be canceled by hitting the Play button again, or by touching the Shutter button. (The 5D is a "shooting priority" camera. It's always ready to shoot a picture, regardless of its current mode. Simply pressing the Shutter button returns it immediately to capture mode.)
Erase Button: Resting beneath the lower right corner of the LCD monitor, this button accesses the Erase menu, which allows you to erase the current image or all images on the card (except for write-protected ones). There is also an option to cancel. The Erase function works in Playback mode and the quick review mode only.
Quick Control Dial: To the right of the LCD monitor on the camera's back panel, this dial selects various camera settings and menu options when turned while pressing a control button or while in an LCD menu screen. When shooting in the Program AE, shutter- or aperture-priority modes, turning the dial within 6 seconds of halfway pressing the Shutter button sets the exposure compensation (from -2 to +2 in one-third or one-half EV increments). In Playback mode, this dial scrolls through captured images on the CompactFlash card. It also navigates the index display and scrolls around within an enlarged image. In Manual mode, the dial sets the aperture.
Set Button (see image above): Located in the center of the Quick Control dial, this button confirms menu selections and camera settings when using the LCD menu system. Through the Custom Function menu, this button can be programmed to control the image quality, parameters, or image playback in conjunction with the Quick Control dial. (The default is for it to have no function in record mode.)
Multi-Controller: Located directly above the Quick Control Dial, this joystick can be moved eight ways, or pressed directly inward, and is used to control AF Point selection and white balance correction, to pan around images when the playback zoom is in use, or to select the area to be trimmed when printing directly from the camera. It also comes into play when using the White Balance Compensation feature.
AE / FE Button: In the top right corner of the rear panel and marked with an asterisk, this button locks the exposure until the Shutter button is pressed. When pressed while the flash is activated, this button locks the flash exposure, which signals the camera to fire a small pre-flash to measure the exposure before locking it. (This decoupling of exposure lock from autofocusing is a very useful "pro" feature seldom seen on lower-end cameras.) Through the Custom menu, you can program this button to lock exposure and focus together, or only one of the variables.
AF Point Selector Button (See image above): Just beside the AE / FE button, this button allows you to choose the focus area manually or automatically in Program AE, Shutter-Priority AE, Aperture-Priority AE, or Manual Exposure modes. Pressing the button and using the Multi-Controller allows you to select either an automatic setting (by pressing in on the Multi-Controller while deflecting it toward the position of the currently selected AF point), or your choice of nine manually-selected focus areas (up, up/left, left, down/left, down, down/right, right, up/right, or the center point - the latter of which is selected by pushing inwards on the Multi-Controller). If you want, you can also use the Main Control Dial to step sequentially through the AF points, instead of the more direct-acting Multi-Controller. When the automatic setting is chosen, all nine AF points illuminate in the viewfinder. The automatic setting lets the camera select the active focus point(s) at the time of exposure, based on the position of the subject within the frame, and its proximity to the nine focusing points (shown as nine small boxes arranged in a diamond pattern in the viewfinder). Whenever you press this button, your current choice of focusing area is reflected in the top-panel LCD data readout by the position of a dash (or series of dashes) in the LCD data readout, as well as in the form of a red-illuminated box in the viewfinder.
