The ultimate flexibility of
Quick Shift Bounce flash
The     lighting system offers a full 
range of external flash units to suit 
virtually any shooting situation. 
At the top of the line stands the 
HVL-F58AM, a revolutionary new flash 
with a Quick Shift Bounce system that 
allows the head to pivot 90° left or 
right, enabling you to maintain 
correct camera/flash orientation 
during both horizontal and vertical 
format  shooting. Class-leading GN58 
(105mm, ISO100•m) power and 
6-level zoom support a wide range of 
lenses, with auto-optimized flash 
coverage to enable use with both 
APS-C and 35mm full-frame sensors.
A host of advanced features,
plus wireless multi-flash control
The powerful HVL-F58AM recharges 
in as little as 3 seconds with nickel 
metal hydride batteries (NiMH) and 
offers high-speed synchronization at 
speeds of up to 1/8000 of a second, as 
well as color temperature-based white 
balance compensation, ADI (Advanced 
Distance Integration) flash metering, 
and a large, easy-to-read LCD panel. 
It also comes with a mini-stand for 
wireless off-camera operation, and 
can be used to control sophisticated 
multi-flash setups comprising up to 
three flash groups, with automatic 
flash ratio calculation to ensure that 
each flash provides the precise 
amount of illumination needed to 
produce the results you want.
