Sony HVL-F20S User manual

Extends ash range beyond camera’s included ash
Though compact and lightweight, the HVL-F20S has a maximum range twice that of the included
ash 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 ash enables shadowless indirect lighting
When set to ‘indoor’ shooting mode, the ash points up to bounce light o the ceiling for
shadowless illumination of your subject. When set to the ‘outdoor’ shooting mode, the ash
directs light directly at your subject.
Built-in diuser for wide and telephoto shooting
With the built-in diuser, the ash 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 ash unit to the ‘Tele’
Position. While the 'Tele" setting reduces the width of ash coverage, it extends the range to
illuminate more distant subjects.
Easy intuitive operation
Unlike most external ash units, the HVL-F20S has no dedicated ON/OFF switch. Instead, power is
automatically switched on simply by raising the ash unit into the shooting position. In addition,
a switch on the side of the unit oers Indoor and Outdoor settings, making it easy to obtain ash
illumination that suits the shooting situation. A charging lamp indicates when the ash is ready to
re.
ADI Flash Metering System
The ADI (Advanced Distance Integration) ash metering system oers the optimum ash metering
and automatic white-balance compensation regardless of the background conditions or
the subject's reectance. ADI ash 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) ash metering. This guide number is calculated
according to distance from the subject, ambient light and pre-ash reectivity of the subject and
the background.
The α Lighting System HVL-F20S is a compact, lightweight ash unit
targeted at rst-time Sony E-mount users. Developed with the goal
of "making it easy to get the best shot” for virtually anyone to take
beautiful photos in low light, the aordably priced HVL-F20S is slim and
stylish enough to keep it mounted on the camera at all times.
