- 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.)
- Flexible adjustment angles of 90° up, 90° left and 180°
right give you greater flexibility for bouncing light
from ceiling, walls or bounce cards.
- The auto zoom coverage is automatically optimized for
the APS-C size or 35mm full-frame size of the image
sensor of the α system camera being used (DSLR-A700,
DSLR-A200 and later models).
- 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.
- 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.
- Recharges
approximately 38% more quickly than
Sony’s previous entry-level
accessory flash (HVL-F36AM), so your α
system DSLR can be ready to catch the
next great moment.
