The Yongnuo YN-568EXIII for Nikon is a full featured flash and is a stellar addition to any lighting kit. This model is directly compatible with Nikon's i-TTL system, which allows you to use the flash on-camera with automatic exposure capabilities and HSS (high-speed sync). It also functions as an optical TTL master for other Nikon-compatible flashes or as an optical TTL slave for either Canon or Nikon systems. It is quite powerful as well with a rated guide number of 58 at ISO 100 and 105mm and is versatile thanks to a head that can tilt from -7 to 90° and rotate 270°.
For controlling light, the flash has a zoom head able to be set from 24-105mm along with a wide-angle panel that optimizes coverage for focal lengths as wide as 14mm. This unit also has a fast recycle time of just two seconds. Operation has been improved as well with an AF-assist light and audio signals available. Additionally, it has a 2.5mm sync port and a USB interface for firmware updates.
