CANON SPEEDLITE 540EZ
Targeted towards professional and advanced amateur users, the 540EZ replaced
the current Speedlite 430EZ as Canon's most sophisticated clip-on type flash
unit. Main features include:
- Full EOS system compatibility
- Warmer color balance and improved flash exposure control reliability
- Higher flash output (Maximum Guide Number: 54/177, ISO 100 m/ft.)
- Extended auto-zoom coverage for focal lengths from 24mm to 105mm
- Built-in wide panel for focal lengths as wide as 18mm
- Exposure confirmation in A-TTL and TTL automatic flash control modes
- Three-zone flash metering for EOS cameras with multi-point AF systems
- Built-in AF auxiliary lamp compatible with 5-point AF when used with
EOS-1N and EOS-1N RS
- Manual flash control at 8 output levels from full power to 1/128
- Improved stroboscopic flash operation up to 100 Hz
(flashes per second)
- Enhanced tilting capability from -7~ for close-ups to 90~ for bounce
flash
- Defeatable Save Energy (SE) function for superior operability
IMPROVED PERFORMANCE WITH FULL COMPATIBILITY
The Speedlite 540EZ is compatible with all EOS cameras. Moreover, any EF lens
can be used as long as the flash coverage angle is sufficient. When used with
an EOS that has multiple focusing points, (such as the newly introduced
EOS-1N and EOS-1N RS, as well as the EOS A2 and A2E and the EOS Rebel X and
XS ), the 540EZ automatically weights its flash exposure in the area of the
active focusing point using the camera's multi~zone flash metering system.
This results in outstanding exposure accuracy with off-center subjects, and
frees the photographer to concentrate on optimum composition. It also makes
the 540EZ especially valuable for capturing peak moments in flash photography
of people and other moving subjects. In other areas of performance, the 540EZ
features improvements in flash exposure control at all shooting distances, as
well as slightly warmer color balance than previous EOS Speedlites for more
pleasing color reproduction of skin tones.
HIGHER OUTPUT PROVIDES MULTIPLE BENEFITS
The 540EZ has a maximum guide number of 54/177 (ISO 100, m/ft.), compared to
43/141 for the previous 430EZ. This powerful light output makes the 540EZ
suitable for virtually any shooting situation. Benefits of the increased
power include faster recycling at short to intermediate range as well as
extended range for fill-in flash and long distance flash photos.
Alternatively, the extra power can be used to increase depth of field for
close-up work through the use of smaller apertures.
EXTENDED ZOOM RANGE PLUS BUILT-IN WIDE PANEL
The 540EZ features an internal motorized zoom mechanism for automatic
adjustment of flash coverage angle in 7 steps from 24mm to 105mm. The zoom
mechanism can also be set manually at 24mm, 28mm, 35mm, 50mm, 70mm, 80mm and
105mm settings. The extended range provides full coverage for popular zoom
lenses such as the EF28-105mm f/3.5-4.5 USM.
A built-in wide panel can be used to increase flash coverage for lenses with
focal lengths as short as 18mm. Ideal for use with Canon's popular EF20-35mm
zoom lenses, the wide panel also diffuses the flash illumination for a
pleasing effect. In addition, the wide panel can be positioned perpendicular
to the flash head. This setting improves the lighting quality of bounce flash
portraiture by adding some sparkle, or catchlight to the subject's eyes.
WIDE VARIETY OF FLASH EXPOSURE MODES
When used with an EOS camera, the 540EZ is capable of everything from simple,
automated flash shooting to advanced techniques such as flash exposure
compensation, automatic flash control based on user-selected shutter speed
and/or aperture settings, manual firing with eight selectable output levels,
and intricate multiple-flash lighting setups using EOS multi-flash
accessories.
A-TTL AUTOMATIC FLASH CONTROL
A-TTL stands for Advanced Through the Lens automatic flash control. When used
with an EOS camera set to Program AE or Full Auto mode, the camera and 540EZ
work together to automatically set the appropriate aperture and shutter speed
for proper flash exposure for indoor and low-light scenes as well as backlit
subjects in daylight. This setting makes fine quality flash photography easy
for anyone in any situation.
TTL AUTOMATIC FLASH CONTROL
TTL automatic flash shooting is possible in other shooting modes such as
aperture-priority AE, shutter~priority AE or manual exposure mode. These
modes allow the photographer to select aperture, shutter speed or both
settings simultaneously while flash exposure is automatically controlled.
FLASH EXPOSURE CONFIRMATION SIGNAL
In A-TTL and TTL modes, the 540EZ provides a flash exposure confirmation
signal using a green lamp that lights for 2 seconds after the picture is
taken to indicate that the flash exposure was correct. This feature is
particularly useful during bounce flash photography.
FLASH EXPOSURE COMPENSATION
The 540EZ features a built-in flash exposure compensation function which
allows the photographer to adjust flash illumination independently from
existing light exposure with all current EOS cameras when coupled directly to
the camera's hot shoe or connected by Off-Camera Shoe Cord 1 or 2. The level
of compensation can be set in 1/3~stop increments up to ~3 stops.
Compensation settings on the 540EZ have priority over the camera's flash
exposure compensation settings.
MANUAL FLASH CONTROL
When desired, 540EZ flash output can be manually controlled at any of eight
individual power settings from full power down to 1/128. The 540EZ's large,
illuminated LCD panel shows all settings clearly, including a distance
reading that's automatically calculated based on power setting, film speed,
focal length and aperture in use. This feature allows the photographer to
adjust camera settings or flash-to-subject distance depending on the desired
result.
STROBOSCOPIC FLASH
For interesting lighting effects, the Speedlite 540EZ can be fired at rates
from 1 to 100 Hz (flashes per second) in its stroboscopic flash mode. This
feature comes in handy when trying to record a range of movement, such as a
golf swing or tennis stroke. It's also a lot of fun for offbeat, creative
flash photos. In addition to the firing rate, users can select the total
number of flashes from 1 to 100, as well as manual flash control settings
down to 1/128 power.
Additional 540EZ features include:
* BOUNCE FLASH: The flash head can be angled upward or to the right or left
for bouncing the flash off of nearby surfaces such as a ceiling or wall to
create a softer lighting effect. The flash head can also be angled 7~
downward to provide full flash coverage for close-up shots.
* AF AUXILIARY LIGHT CORRESPONDING TO FIVE FOCUSING POINTS: The built-in AF
auxiliary light automatically fires in low light and low-contrast situations
to aid the camera's autofocusing system. When combined with the EOS-1N or
EOS-1N RS, the AF auxiliary light emission automatically corresponds to the
camera's five autofocusing points. The effective distance range for the
central focusing point is 0.5~15m/1.6~50 ft.
* FLASH SYNC TIMING: The sync timing can be set to either first-curtain sync,
which fires the flash as soon as the shutter is fully opened, or
second-curtain sync, which fires the flash immediately before the shutter
closes.
* SE (SAVE ENERGY) FUNCTION: When the flash is set to SE mode, the power
automatically turns off after 90 seconds of non-operation in order to
conserve battery power. A 3-position main switch allows full-time operation
as well, ideal for remote operation.
* MODE MEMORY: All flash settings are automatically memorized when power is
shut off, and are even retained for up to 90 seconds while changing batteries.
* RETRACTABLE SHOE LOCK: A spring-loaded locking pin on the accessory shoe
ensures a secure fitting to EOS cameras equipped with a matching socket.
EXTERNAL DESIGN
The body of the 540EZ has been designed to meet the following objectives:
* RELIABILITY: Speedlite 540EZ is constructed to the highest standards of
reliability and quality to meet the needs of demanding professional
photographers who use electronic flash regularly.
* OPERABILITY: Control buttons are large for ease of use but recessed to
prevent inadvertent operation. A 2~step procedure allows users to select and
lock in critical settings such as flash exposure compensation.
* DISPLAY PANEL READABILITY: The size of the LCD panel is 2.3 times larger
than that of the 430EZ, with priority placed on improving overall
readability. A built-in illuminator is available at the touch of a button for
easy visibility under any shooting conditions.
POWER SOURCES
Speedlite 540EZ runs on 4 AA-size batteries. Users can freely select
alkaline, rechargeable Ni-Cd or the new AA~size lithium cells. The 540EZ is
also fully compatible with dedicated external power supplies such as Canon's
popular Compact Battery Pack E and Transistor Pack E, which are already on
the market for use with Speedlites 480EG and 430EZ. Their additional power
extends the versatility of the 540EZ for professional flash photography by
reducing recycling time between flashes and increasing overall shooting
capacity.
SYSTEM ACCESSORIES FOR PROFESSIONAL LIGHTING TECHNIQUES
Canon's line of dedicated flash accessories for Speedlite 540EZ includes
Off-Camera Shoe Cord 2 for separating the flash from the camera, as well as
adapters and cords for configuring elaborate multiple flash set-ups. Even
when using more than one flash, exposure can be controlled automatically by
the EOS TTL system.
