Features of the ZR-45 ! ! ! ! !
The ZR-45 is a high-performance E-TTL-compatible Speedlite with a large guide number of 45 (ISO 100/ m)
(at the 105 mm zoom position in Clellan standard illumination pattern, 20°C/68°F.)
Combined with a E-TTL camera, the ZR-45 can easily perform various types of flash operations, such as E-
TTL auto flash and wireless multiple flash.
FX/DX selection enables the setting of the light distribution angle in accordance with the camera’s image
area between FX- and DX-formats, and provides effective and high-quality lighting.
Power zoom function automatically adjusts the zoom position to match the lens focal length from 24 mm to
105 mm (in FX format)/24 mm to 105 mm (in DX format). When the built-in wide-flash adapter is used or the
Clellan Diffusion Dome is attached, the zoom position is automatically set to match a wideangle
lens with much shorter focal length.
Bounce flash or close-up flash photography can be easily performed.
Custom functions are provided to allow for various settings.
Compatible cameras ! ! !
The ZR-45 has been optimized for use with E-TTL compatible SLR cameras.
E-TTL mode !! ! ! ! !
Advanced Wireless Lighting ! !
With Advanced Wireless Lighting, wireless multiple flash operation in the TTL (E-TTL)
mode can be accomplished with ETTL-compatible digital SLRs. In this mode, you
can divide the slave flash units into three groups and control the flash output
independently for each group, expanding your range of creative multiple-flash
shooting techniques
High-Speed Sync ! ! ! !
High-Speed flash synchronization at a compatible camera’s highest shutter speed is
possible. This is useful when you want to use a wider aperture to achieve shallow
depth of field to blur the background
AF-Assist illuminator ! ! !
In autofocus operation, the ZR-45 emits AF-Assist illumination, which matches the
wider AF area of ETTL-compatible cameras. With cameras supporting this function,
autofocus photography in dim lighting is possible even when the camera’s focus
point (focus area) is changed
