Sony External Flash For Alpha NEX Cameras, Model HVLF20S
Expand your creativity with your a NEX interchangeable lens camera and the
HVL-F20S external flash. This external flash extends the illumination range
beyond the camera's included flash. Bounce flash enables shadowless indirect
lighting while TTL (through the lens) flash exposure is automatically controlled
by your a NEX 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-F20S has a maximum range twice that
of the included flash units of the NEX-3, NEX-5, and NEX-C3 cameras. 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-F20S 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
- 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
