display. After autofocus has executed, the mirror
flips up, and the Live View image is restored.
The Live mode uses the image sensor to per-
form contrast-detection AF. The Multi-controller
can be used to select the AF point. The Live
Face Detection Mode uses contrast AF to detect
the human face. If multiple faces are detected,
the largest face closest to the center is automat-
ically selected as the autofocus point. The pho-
tographer can use the Multi-controller to select
a different face for AF as desired.
A Grid display can be superimposed during
Live View to aid in composition. There are two grid
choices: two horizontal and two vertical or five
vertical and three horizontal lines.
Picture Style Presets
The myriad features and settings
available to the digital SLR user can be daunting
— even for seasoned professionals. Canon
Picture Style presets offer an ingenious solution,
providing a library of useful preprogrammed
camera settings that can be instantly recalled as
needed based simply on the type of shooting.
The EOS-1D Mark IV provides six factory preset
styles and enables the photographer to program
3 additional custom presets. To create a cus-
tom Picture Style, the user can start with one
of the base style presets above and modify
it before saving as a user-defined preset.
Versatile Recording Options
The EOS-1D Mark IV provides a comprehensive
set of JPEG and RAW recording options. They
greatly enhance shooting flexibility, enabling
the photographer to select pixel dimensions
appropriate to the assignment and reducing file
sizes when necessary to streamline data transfer
and storage. The photographer can select from
among four JPEG and three RAW image sizes.
JPEG images can be compressed to any of ten
size/quality levels. A dedicated, clearly organ-
ized image size setting menu screen facilitates
selection of recording options.
UDMA Recording
The EOS-1D Mark IV fully supports the UDMA
(Ultra Direct Memory Access) Mode 6 standard.
With UDMA CF cards, data write/read operations
are significantly accelerated.
is also possible via a Custom Function. Partial
metering reads approximately 13.5% of the
viewfinder area, while Spot metering reads approx-
imately 3.8%. The Multi-spot mode automatically
averages measurements taken from up to eight
spot readings. The E-TTL II autoflash system uses
the same 63-zone metering sensor and makes use
of distance information from the lens to ensure
accurate flash exposures even with highly reflective
backgrounds. For both regular and flash shooting,
the EOS-1D Mark IV provides a new AE microadjust-
ment feature that enables the photographer to
fine-adjust “standard” exposure. Adjustments up to
±1 stop can be made in 1/8-stop increments.
Auto Lighting Optimizer
The Auto Lighting Optimizer automatically
adjusts brightness and contrast during image
processing. With RAW images, Canon Digital
Photo Professional (DPP) software can be used
to make use of the Auto Lighting Optimizer.
Auto Lighting Optimizer is available in most
shooting modes, including Manual mode.
Standard, weak, or strong processing as well as
an option to disable.
Lens Peripheral Illumination Correction
The EOS-1D Mark IV incorporates a sophisticated
feature that automatically corrects for light fall-
off at the four corners of an image. Since
peripheral illumination characteristics vary for
each lens, this corrective system relies on a
registered database. With JPEG images, the cor-
rection is performed in-camera at the time of
capture. With RAW images, the same correction
can be performed post-capture using Canon
DPP software. The EOS-1D Mark IV includes
pre-registered data for approximately 30 Canon
lenses. The camera can, however, store correc-
tion data for about 40 lenses. Lens data can be
added or deleted using the EOS Utility. When
the feature is enabled, correction is automati-
cally applied whenever there is corresponding
data for the attached lens. (Note that in-camera
correction is about 70% of what can be performed
in post-processing using Canon DPP software.)
Highlight Tone Priority
The Highlight Tone Priority feature is activated
via a Custom Function on the EOS-1D Mark IV. It
employs advanced exposure and processing
algorithms, taking advantage of the sensor’s
wide native dynamic range to address a peren-
nial problem for digital photographers — loss of
image detail in highlight areas, especially in
bright sunlight or contrasty studio lighting. This
feature extends the usable capture range of
highlights by about one stop and improves gra-
dation within highlight areas. By expanding the
range from the correct exposure level to the
maximum allowable highlight level, the grada-
tion from the grays to the highlights becomes
smoother and loss in highlight detail is minimized.
Depending on shooting conditions, noise in
shadowed areas may increase slightly.
Enhanced Live View
Whether shooting stills or video, photographers
can make use of advanced Live View functionality
to compose images using the large, high-resolu-
tion LCD monitor on the EOS-1D Mark IV. The
various Live View settings can now be accessed
via a centralized function screen for easier use.
Via the function screen, the user can enable
or disable
Live View
and choose
whether to
use it for
stills only or
for both stills
and movies.
In Live View mode, the camera uses Evaluative
metering via the image sensor. Camera menus
can be accessed and image playback performed
while in Live View mode — the display will revert
to Live View when the user is finished with menu
and image playback functions. Shooting options
— such as drive mode, ISO speed, Picture Style,
white balance and AF mode — can be selected
while in Live View mode.
For still shooting, the EOS-1D Mark IV Live
View mode provides a choice of three AF
modes. In Quick Mode, the AF sensor is used
for phase-difference detection. The camera
defaults to One-Shot AF mode, and the user can
opt for auto or manual AF point selection. When
the shutter release button is partially depressed
or the AF Start button is pressed, the mirror
goes down, momentarily interrupting the live
Easy File Transfer
The new plug-in will allow for simple and easy
transfer of video content from Canon’s EOS
DSLR cameras directly into Final Cut Pro. The
EOS MOVIE Plugin-E1 will take advantage of
Final Cut Pro’s powerful Log and Transfer
feature, which allows users to select video for
import from the memory card, add custom
metadata and ingest the clips in the back-
ground so the editing can begin immediately.
The plug-in will be compatible with Final Cut
Pro 6.06 or higher and currently supports
Canon EOS 5D Mark II, EOS 7D and EOS-1D
Mark IV cameras.
Professional Pedigree
Better Flash Photography
The advanced automatic exposure system of
the EOS-1D Mark IV includes an upgraded flash
metering algorithm that reduces overexposure
with wide-angle shots in which the main subject
occupies a small area. E-TTL II autoflash control
is possible with all Canon EX-series Speedlite
flash units. Moreover, with the Speedlite 580EX
II, 430EX II and 270EX, all flash settings can be
controlled via the camera menu and Custom
Functions. (Limited camera control is available
for other Speedlite models.)
63-Zone Metering System
The EOS-1D Mark IV incorporates a 63-zone
metering sensor linked to the 45 AF points. The
metering range is EV 0 to EV 20 (at 73°F/23°C,
50mm f/1.4 lens, ISO 100). Photographers can
choose from the following metering modes:
Evaluative, Partial, Spot, Multi-spot and Center-
Weighted average. AF point-linked spot metering
EOS Full HD Video:
An Exciting New Tool for
Motion Picture Capture
Unique Video
With the introduction of Canon EOS
digital SLRs capable of Full HD video
capture, professional photographers, videogra-
phers and cinematographers have at hand an
important new imaging tool. They have discov-
ered not only the convenience, but also the
very special qualities of Canon EOS HD Video.
By shooting video with a large sensor camera,
it’s simple to take advantage of the image
quality and characteristics intrinsic to SLR pho-
tography. The EOS-1D Mark IV increases flexibility
for the photographer in that it also allows for
full use of Canon’s EF and EF-S lenses, including
wide angle, macro, tilt-shift and fish-eye,
providing a wealth of depth-of-field and other
creative shooting options once reserved only
for still photography. The resulting HD video is
unique in its incomparable depth-of-field
characteristics, remarkable capture capability
under poor lighting conditions and deep clean
blacks with undetectable noise.
Comprehensive Choice of Frame Rates
and Formats
The EOS-1D Mark IV is the first EOS-1 series
digital SLR to provide video capture capability,
and, not surprisingly, it sets new standards for
image quality and professional versatility. It
supports a wide range of frame rates and video
formats, enabling photographers to tailor their
raw footage to specific needs and markets.
Video is captured with progressive scan-
ning and recorded in the MOV format (MPEG-4
AVC/H.264 video, uncompressed linear PCM
audio) using a variable bit rate. This ensures
high-quality image and sound while keeping
file size to a minimum.
Advanced Exposure Control
When shooting HD video, including Full
HD, the EOS-1D Mark IV employs Center-
Weighted average metering (using the
imaging sensor) to ensure stable motion
picture exposure. If the AF mode is set to
Face Detection Live View, the camera will
use Evaluative metering linked to the AF point
corresponding to the face to calculate exposure.
In P, Tv, Av and Bulb shooting modes,
ISO speed is automatically set between
100 – 12,800 and shutter speed is auto-
matically set between 1/30 – 1/4,000 sec-
ond at 30/25/24 fps and between 1/60 –
1/4,000 second at 60/50 fps. With these
shooting modes, aperture is also automat-
ically selected. (If ISO speed expansion
has been selected, the range can be
extended to 102400.) As with still shoot-
ing, AE lock is available for video.
Exposure compensation is available in the
range of ±3 stops.
Full manual exposure control can also be
used when shooting video. ISO speed can be
set automatically or manually between 100
and 12800. Shutter speed can be manually
set up to a maximum of 1/4,000 second.
Available aperture settings are specific to
the lens used.
Sound Recording Options
A built-in microphone below the camera
nameplate records monaural sound. Stereo
recording is possible with an external stereo
microphone connected to the camera’s mic
input connector (a standard 3.5mm stereo
jack). Audio levels are automatically adjusted
whether recording with the built-in or an
external microphone.
HDMI Connectivity
An HDMI output port is provided for full-
resolution digital transfer of still and video
Live View and playback of images to studio
monitors, projectors and other post-produc-
tion equipment.
Switching the shooting information display
The EOS-1D Mark IV captures Full HD (1920 x
1080) at 30 (29.970) fps for NTSC, 25 fps for PAL,
and 24 (23.976) fps for cinematography, Standard
HD (1280 x 720) at 60 (59.940) fps for NTSC and
50 fps for PAL, and SD (VGA – 640 x 480) at 60
(59.940) fps for NTSC and 50 fps for PAL.
