The Sony HVL-F46RM Flash is a fast-output portable lighting system designed to integrate seamlessly with the Sony a7 series and a1. With select cameras it can sync at shutter speeds up to 1/400th of a second and fire up to 10 flashes a second. Here are the other standout features of this flash:

• Detailed communication with compatible camera bodies for reliable and precise control, including with face detection features and auto white balance.
  
• Efficient use of power with a set of AA batteries (not included) providing up to 240 flashes with a 1.7 second recycle time.
  
• Innovative overheating protection for longer shooting sessions.
  
• With select cameras using only electronic shutter, achieve up to 20 flashes per second speeds.
  
• High-speed control sequencing that uses pre-flash to control each firing during burst shooting, making tracking fast-moving subjects in changing light much easier.
  
• With compatible cameras, control your flash compensation, ratio, and other features directly on the camera. For controlling flash parameters on the flash itself, dedicated level buttons allow for speedy compensation control.
  
• Wireless radio control of up to 15 flashes. Can also communicate with non-radio-equipped flashes and strobes with the Sony FA-WRC1M Wireless Radio Commander and Sony FA-WRR1 Wireless Radio Receiver.
