Product Description
Expand your creativity with the revolutionary HVL-F20AM compact external
flash, which extends illumination range beyond the camera's built-in flash.
Bounce flash enables shadow-less indirect lighting while TTL (through the lens)
flash exposure is automatically controlled by your α DSLR for easy and intuitive
operationall in an ultra-compact design which folds flat when not in use.
Extends flash range beyond camera's built-in flash
Though compact and lightweight, the HVL-F20AM has a maximum range twice that of
the built-in flash units on α230, α330 and α380 cameras. This is represented as
the guide number (GN) of 20 with a 50mm focal distance at ISO 100.
Bounce flash enables shadowless indirect lighting
When set to 'indoor' shooting mode, the flash points up to bounce light off the
ceiling for shadowless illumination of your subject. When set to the 'outdoor'
shooting mode, the flash directs light directly at your subject.
Built-in diffuser for wide and telephoto shooting
With the built-in diffuser the flash illumination covers an angle of view of
27mm at the default Standard Position setting. If users want to to shoot at a
greater distance, they can rotate the dial on the side of the flash unit to the
'Tele' Position*. Although this reduces flash coverage to an angle of view of
50mm, it extends the range to illuminate more distant subjects.
Easy intuitive operation
Unlike most external flash units, the HVL-F20AM has no dedicated ON/OFF switch.
Instead, power is automatically switched on simply by raising the flash unit
into the shooting position. In addition, a switch on the side of the unit offers
Indoor and Outdoor settings, making it easy to obtain flash illumination that
suits the shooting situation. A charging lamp indicates when the flash is ready
to fire.
Light (90g / 3.2oz), slim (24mm / 1") ultra-compact design
With a weight of only 90g (approx.) and a thickness of only 24mm (1 inch), the
HVL-F20AM is so compact it can simply be folded down and left mounted on the
camera when it is not in use, or detached and carried in a shirt pocket. When
removed from the camera, the flash unit's hot shoe can be folded to the side,
making the body even more compact.
Elegant and attractive styling
Viewed from any angle, the HVL-F20AM's revolutionary body is sleek, slim, and
virtually protrusion-free. The new design also eliminates the LCD display panel
found on many conventional flash units, further contributing to easy-use
simplicity and stylish design.
ADI Flash Metering System
The ADI (Advanced Distance Integration) flash metering system offers the optimum
flash metering and automatic white-balance compensation regardless of the
background conditions or the subject's reflectance. ADI flash metering works in
combination with α cameras and lenses that incorporate a distance encoder. When
used with these lenses, the camera calculates a guide number to control TTL
(through the lens) flash metering. This guide number is calculated according to
distance from the subject, ambient light and pre-flash reflectivity of the
subject and the background.
Wireless flash trigger function (DSLR-A900 only)
When teamed with the α900, the HVL-F20AM can also be used to trigger wireless
flash setups. Please note, however, that this functionality is only available
with DSLR-A900, and does not include luminosity ratio control.
