Features & Controls (cont.)

The back of the EOS-1D Mark III has a brilliant 3 inch color LCD. You use the LCD review your images and access the menu system. The controls are well laid out and highly functional. The color LCD gives you nearly 100% coverage when reviewing your images and displays 230,000 pixels.

Controls on the back of the camera (left from top to bottom): MENU calls up the menu system on the color LCD. Next to it is the INFO button. Below the LCD, on the left, is the PLAYBACK button. And you see the smaller, rear monochrome LCD Info Panel towards the bottom.

The eye level viewfinder offers 100% coverage vertically and horizontally. It has a 20mm eye point and -3.0 to +1.0 diopter correction. On the back right side is the eyepiece shutter lever to block light from entering during self timer or long shutter exposures and the diopter correction knob is on the left side.

Here's the layout inside of the viewfinder. Shown is the standard focusing screen layout, however there are other focusing screens available as options from Canon. In the center of the viewfinder you can see the Spot metering circle, the Area AF ellipse and the 45 AF point (Cross-type and Assist AF) indicators. On the right side is the Exposure level indicator, the Maximum Burst frame indicator, the JPEG, RAW and Battery check icons.

Along the bottom of the viewfinder is the status line showing the Metering mode, Manual exposure, the "*" for AE lock / AEB in-progress or Multi-spot metering, the Flash Ready / Improper FE lock warning icon, the "Bolt + H" is for High-speed flash sync, "Bolt + *" is the FE lock. Next we see the AF Point selection mode, shutter speed, aperture, exposure compensation, White balance correction, shots remaining, ISO speed, and Focus confirmation light.

The monochrome LCD Info Panel on the top of the camera displays several camera settings such as shutter speed and aperture values, exposure mode, ISO speed, focus mode, metering mode, drive mode, flash mode, exposure compensation, exposure bracketing, self timer and battery status. Both the top and back LCD Info Panel displays can be illuminated, by a highly visible blue back light, by pressing the "light bulb" icon on the top of the EOS-1 D.

Behind the top monochrome LCD Info Panel along the back edge of the camera, from left to right, are the AF on button, AE Lock/Reduce button and the AF point selection/Magnify button. These buttons are duplicated on the bottom right of the camera for use in conjunction with the vertical grip shutter release.

And speaking of the vertical grip, here it is, shown from the side. The On/Off switch prevents an accidental tripping the shutter. There is a shutter release, main command dial and FEL button on the front, the AEL, Assist and AF frame selection buttons are on the back.

The EOS-1D Mark III uses both Compact Flash and Secure Digital memory cards and you can have both in the camera simultaneously. In fact you can choose to record images on either card or both cards at the same time. Both Type 1 and Type II CF cards are usable. I also used a Seagate 5 gig ST1, CF hard disk-type card.
