This Nikon 1 SB-N5 Speedlight for V Cameras is designed for use with the Nikon V CX format mirror-less cameras. The SB-N5 mounts to the V camera's multi-accessory port and is powered by the camera--no batteries required. This convenient featherweight (2.5 oz/70 g) flash has a guide number of 27.9' (8.5 m) at ISO 100 and is i-TTL compatible. Exposure modes include Fill Flash, Front- and Rear-Curtain sync and slow-sync and flash compensation.
The effective flash range is 2 to 66 feet, depending on ISO, bounce angle, and aperture, and the head both tilts up 90° and swivels 180° to both right and left. Flash duration is 1/4000 second at full power. Electronic construction consists of Automatic Insulated Gate Bipolar Transistor (IGBT) and series circuitry. A capture illuminator lights for six seconds using Smart Photo Selector and Motion Snapshot modes. And, yes, there is a flash-ready indicator.
