The Freedom of Accessory Flash
The Sony HVL-F42AM Flash Unit can
improve formal portraits, brighten low-
light scenes, bounce lighting to soften
shadows and illuminate the entire
frame, provide fill-in flash for backlit
shots and expand your creative
freedom with complex lighting effects
to give shots greater depth, erase or
define shadows and bring hidden
details into view.

More Power, Longer Range
High illumination output in a small
lightweight body, with effective range
greater than 30 feet (10.5m) and guide
number 42. (Guide number measures
the illumination capability of the flash;
the higher the number, the more light the
unit can provide. Tested at ISO100,
105mm.)

Versatile Bounce Angle
Flexible adjustment angles of 90° up,
90° left and 180° right give you greater
flexibility for bouncing light from
ceiling, walls or bounce cards.

Auto WB Adjustment
Intelligent features of the HVL-F42AM
include the power to adjust white
balance automatically -- with color
temperature information signaled to the
&
945 camera before WB is adjusted.

Auto Zoom Control
The auto zoom coverage of the HVL-
F42AM is automatically optimized for
the APS-C size or 35mm full-frame size
of the image sensor of the &
945 system camera being used (DSLR-
A700, DSLR-A200 and later models).

Wide-Angle Coverage
The HVL-F42AM automatically adjusts
flash for focal-length settings from
24mm to 105mm -- and a built-in, slide-
out wide-angle panel increases wide-
angle coverage to 16mm.

Wireless Operation
Sony á cameras feature an operating
mode that sends wireless signals to one
or more HVL-F42AM Flash Units,
allowing you to operate and adjust off-
camera flash lighting setups with
greater ease.

High-Speed Sync
Conventional flash only works well at
shutter speeds from 1/125 to 1/250 of a
second. The Sony HVL-F42AM Flash Unit
provides High-Speed Synchronization
mode that enables flash sync with
shutter speeds from 1/500 to 1/4000 of
a second to catch fast-moving subjects.

ADI Flash Metering
ADI (Advanced Distance Integration)
metering capability enables the HVL-
F42AM to work more effectively with
lenses equipped with distance encoders
-- combining TTL (through-the-lens) flash
metering with guide number control
calculated automatically according to
the distance to the subject, the ambient
light and the pre-flash reflectivity of the
subject.

Simple Controls, Flash Test Button
Flash controls are simple and easy to
operate -- and a quick-reference flash
test button provides both flash ready
(amber) and proper exposure (green)
signals.

Fast Recharging Time
The HVL-F42AM Flash Unit recharges
approximately 38% more quickly than
Sony’s previous entry-level accessory
flash (HVL-F36AM), so your &
945 system DSLR can be ready to catch
the next great moment.
