A born wide panel tin be used to increase flash coverage for lenses with focal lengths as short every bit 18mm. Ideal for use with Canon's popular EF20-35mm zoom lenses, the broad console likewise diffuses the flash illumination for a pleasing consequence. In addition, the wide panel can be positioned perpendicular to the flash caput. This setting improves the lighting quality of bounce flash portraiture by calculation some sparkle, or catchlight to the subject'southward eyes.

Wide VARIETY OF Wink EXPOSURE MODES

When used with an EOS camera, the 540EZ is capable of everything from simple, automated flash shooting to advanced techniques such as wink exposure compensation, automatic flash control based on user-selected shutter speed and/or aperture settings, transmission firing with 8 selectable output levels, and intricate multiple-flash lighting setups using EOS multi-wink accessories.

A-TTL Automatic Flash Command

A-TTL stands for Advanced Through the Lens automated flash command. When used with an EOS photographic camera set to Program AE or Full Automobile style, the photographic camera and 540EZ work together to automatically gear up the advisable aperture and shutter speed for proper flash exposure for indoor and depression-calorie-free scenes every bit well every bit backlit subjects in daylight. This setting makes fine quality wink photography easy for anyone in any situation.

TTL AUTOMATIC FLASH CONTROL

TTL automated flash shooting is possible in other shooting modes such as aperture-priority AE, shutter~priority AE or manual exposure manner. These modes let the photographer to select aperture, shutter speed or both settings simultaneously while wink exposure is automatically controlled.

FLASH EXPOSURE CONFIRMATION Indicate

In A-TTL and TTL modes, the 540EZ provides a flash exposure confirmation betoken using a dark-green lamp that lights for 2 seconds after the picture is taken to indicate that the flash exposure was correct. This feature is peculiarly useful during bounce flash photography.

FLASH EXPOSURE Compensation

The 540EZ features a built-in wink exposure compensation part which allows the lensman to adjust flash illumination independently from existing light exposure with all current EOS cameras when coupled directly to the camera'due south hot shoe or connected by Off-Camera Shoe Cord 1 or two. The level of bounty tin be set in one/iii~stop increments up to ~iii stops. Bounty settings on the 540EZ have priority over the camera'south flash exposure compensation settings.

Transmission FLASH Control

When desired, 540EZ flash output can exist manually controlled at any of eight individual ability settings from full ability down to 1/128. The 540EZ's large, illuminated LCD panel shows all settings clearly, including a distance reading that'south automatically calculated based on power setting, film speed, focal length and discontinuity in use. This characteristic allows the photographer to adapt camera settings or flash-to-subject altitude depending on the desired issue.

STROBOSCOPIC Flash

For interesting lighting effects, the Speedlite 540EZ tin can be fired at rates from 1 to 100 Hz (flashes per second) in its stroboscopic wink way. This feature comes in handy when trying to record a range of movement, such as a golf swing or tennis stroke. Information technology's too a lot of fun for offbeat, creative flash photos.
