Sony External Flash, Model HVLF20M
Expand your creativity with your compatible Alpha NEX interchangeable lens
camera or Alpha DSLR camera and the HVL-F20M external flash. This compact and
lightweight flash extends the illumination range beyond the camera's built-in
flash and includes Sony's multi-interface shoe for expanded compatibility. Bounce
flash enables shadowless indirect lighting while TTL (through the lens) flash
exposure is automatically controlled by your camera for easy and intuitive operation.
There's also a built-in diffuser which is ideal for wide and telephoto shooting.
- Extends flash range beyond camera’s included flash
Though compact and lightweight, the HVL-F20M has a maximum range twice that
of the included flash units of the NEX-6 or SLT-A58K and includes Sony's new
Multi Interface shoe for expanded compatibility. This is represented as the
guide number (GN) of 20 with a 50mm focal distance.
- 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 a wider angle of
view or 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. While the 'Tele"
setting reduces the width of flash coverage, it extends the range to illuminate
more distant subjects.
- Easy intuitive operation
Unlike most external flash units, the HVL-F20M 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
quickly moves the flash from direct to bounce, making it easy to obtain flash
illumination that suits the shooting situation. A charging lamp indicates
when the flash is ready to fire
- 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 a 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.
