Expand your creativity with your Alpha NEX-6 interchangeable lens camera or Alpha a58K 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.
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.
Bounce flash enables shadowless indirect lighting
When set to indoor shooting mode, the flash po ints 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.
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 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.
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.

No matter what I tried on A7: P, Auto, Bounce, Direct, whatever its just over overexpose and camera reports 'accessory is not supported'.
Bought this for my A7. It is very small and lightweight and has everything I expected. Highly recommended.
