Professional Features

Revised and Simplified Operation

In order to provide the ease of operation that befits

a new-generation EOS-1D series camera, Canon

has thoroughly investigated ways to make camera

operation easier. The camera now uses the EOS

Digital line’s basic operation method with the

Main Dial, Quick Control Dial, Multi-controller,

SET button, and other buttons to select and set

various functions. Also, the ISO speed button,

AF Start (AF-ON) button, Picture Style button, and

Memory selection/Image size/White balance

function button have been newly added to make

camera operation easier.

With the older EOS-1D series cameras, the basic

shooting operation logic consisted of holding

down a button and turning the Main Dial or Quick

Control Dial to select a setting. However, with

the new Mark III series, when you press a but-

ton, it remains active for a while so you can let

it go and then turn a dial to set something.

Several buttons are multi-purpose—press once

and turn either the top Main Dial or rear

Quick Control Dial for the respective functions.

The Multi-controller on the rear is new. It’s used

to select Menu headings, and provides several

AF functions as well. If the AF point select button

is pressed once, a push on the Multi-controller

toggles between selecting the center AF point

and Automatic AF point select mode. You can

also memorize any of the 19 user-selectable AF

points, and instantly jump back to it by pressing

the Multi-controller.

New Recording Options

The EOS-1Ds Mark III and EOS-1D Mark III offer

some highly flexible image recording options.

With the Wireless File Transmitter WFT-E2A, users

can download directly to a compatible portable

USB hard drive. Compatible devices range from

popular and convenient USB thumb drives to

many portable USB hard drives. With the CF

card, SD card, and external media, the following

recording functions can be used:

• Standard: Images are recorded onto one card

(or connected hard drive).

• Automatic switching of recording media: When

the current recording medium becomes full,

the camera switches to another automatically

and continues recording without interruption.

• Separate recording: A captured image can be

recorded in different image sizes on different

media. Each recording medium can be set to

record a specific image size (L, M1, M2, S,

RAW, sRAW) for each shot.

• Recording of identical images: A back-up mode,

this records the exact same file type and size

onto two cards and/or a connected hard drive.

SDHC (SD High-Capacity) is a new memory card

standard (SDA Ver.2.00) established by the SD

Card Association in 2006 to handle high-capacity

data from 2GB to 32GB. Because it is compatible

with SDHC, the camera can be used with SD cards

having a capacity up to 32GB.

The number of possible shots (battery life) and continuous shooting

speed are based on Canon’s testing standards and a 1GB CF card.

The size of one image, number of possible shots (battery life), and

continuous shooting speed are based on JPEG quality 8, ISO 100,

and the Standard Picture Style. (These figures vary depending on

the subject, memory card brands, ISO speed, Picture Style, etc.)

Camera Control Modifications

Ec-series focus screens can be used in the both

cameras. Since the eyepiece frame now has a

different shape to accommodate the bigger eye-

piece lens, new Eg-series viewfinder accessories

dedicated to both the cameras have been

developed at the same time:

Eyecup Eg, Dioptric

Adjustment Lenses Eg

(7 types: -4, -3, -2, 0,

+1, +2, +3), and Anti-

fog Eyepiece Eg. Note that

the old EOS-1 viewfinder accessories Eyecup

Ec-II, Rubber Frame Ec, and Anti-fog Eyepiece Ec

are not interchangeable with the Eg-series

accessories. The newly-developed, standard

Eyecup Eg has an improved mount for attaching

it to the eyepiece. It is now less likely to detach

inadvertently compared to the old eyecup.

Wide-view 3.0-inch LCD Monitor

The large, 3.0-inch TFT monitor (1.4 times larger

in area than 2.5-inches) features approximately

230,000 pixels, a wide viewing angle (140°

both vertically and horizontally), high-level

brightness, and low power consumption. The

LCD monitor is backlit with four LED modules.

The maximum brightness makes it easier to see

the image on the

LCD monitor even

in bright outdoor

conditions. The

seven brightness

adjustment levels

make the camera

more adaptable to environmental conditions. A

large, clear grey scale is provided for guidance.

Also, the color reproduction range has been

increased to more closely simulate a personal

computer monitor. The LCD monitor is not only

larger, but easier to use and displays more

informative than ever.

The viewfinder’s optics have been developed to

achieve best-in-class performance. A highly

refractive material is used for the pentaprism

of the EOS-1Ds Mark III and EOS-1D Mark III.

To improve viewfinder magnification, a larger

pentaprism is employed. The basic configuration

of the eyepiece optics is with four lens elements.

However, by increasing lens power, high magnifi-

cation is attained. Finally, the finder’s parts are

fabricated with greater precision for more con-

sistent performance at higher magnifications.

The Ec-C IV focusing screen is a Laser Matte unit

whose molding method has been improved over

the previous Ec-C III focusing screen’s. It makes

it easier to focus and provides natural-looking

background blur (bokeh). It is also brighter and

less grainy, making it a very well-balanced

focusing screen. With the improved molding

method, image transfer is better. The dispersion

characteristic is improved, and the screen is

brighter with minimal flare. Brightness at the

outer edges, in particular, is improved over

previous 1-series cameras. The Ec-C IV focus

screen gives superb contrast and visual “snap,”

making it easy for photographers to tell when

an image pops into sharp focus. All previous

New Shutter, Tested to 300,000 Cycles

The EOS-1Ds Mark III

and EOS-1D Mark III’s

shutter unit have

been improved to

increase durability

and to reduce the

generation of dust.

It is now rated for 300,000 shutter cycles, a

figure unsurpassed by any other digital SLR (as

of January 2008). To attain this level of rugged-

ness, surface finish and heating processes in

manufacturing have been changed for specific

highly durable parts. To increase stability and

shutter precision, a PR (Photo Reflector) is

newly employed to detect the slit-passing time.

For the X-sync contact, the mechanical contact

has been eliminated to prevent contact scorch-

ing and wear.

By employing PR signals for the electronic X-sync

contact (a semiconductor switch), reliability is

improved. By optimizing the sync timing, an X-sync

speed of 1/300 second is now attained with

EX-series Speedlites.

Weather-resistant System

The legendarily excellent water- and dust-resistant

construction measures are incorporated at 76

places around the camera controls and along

cover seams. Also, O-rings are used on the

memory card slot covers and the battery com-

partment, and silicon rubber is employed around

the top and rear covers and buttons where the

user can see it and feel reassured. The cameras’

hot shoe is shaped to

resist water with a rib

around its perimeter.

When the Speedlite

580EX II is attached,

water resistance is maintained. When a water-

resistant EF lens is attached to the camera, the

entire camera-and-lens outfit will be moisture-

and dust-resistant.

New Viewfinder

The viewfinder optics are entirely new, and it’s

now easier to see, clearer and sharper. The

viewfinder has approximately 100% coverage,

0.75x (EOS-1Ds Mark III)/0.76x (EOS-1D Mark III)

magnification, a 35° (EOS-1Ds Mark III)/30°

(EOS-1D Mark III) angle of view, a 20mm eyepoint,

-3 to +1 dpt. dioptric adjustment, and an eyepiece

shutter which is now gray to make it easier to see

when it is closed.
