Expand your creativity with your Alpha 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 Alpha 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
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:
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 Alpha 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
Specifications:
Flash Coverage: F4: 1m -5m
Guide Number: 20
Dimensions (Approx.): 2 3/8 x 2 7/8 x 2 1/8inches; 60 x 71 x 53mm (WxHxD)
