Yongnuo YN-622N-TX 7-Channel i-TTL Wireless Flash Controller for Nikon Cameras

Offering a fantastic blend of affordability, features, and build quality, Yongnuo's line of speedlights and flash accessories offer enormous creative potential. This particular wireless flash controller has an LCD menu for you to monitor controls, settings, and light readings for each shot, as well as a test button, controls for zoom, and more. The unit supports mixed use of up to three flash groups using i-TTL, manual, or super-sync flash modes, and it can make adjustments to the exposure compensation or flash output of each group as well. In addition to these control features, it supports different focal lengths for up to three groupings while utilizing an AF-assist beam emitter. The relatively high sync speed will add an extra dimension to your shots, allowing you to shoot at higher shutter speeds without limiting yourself to natural lighting and letting you make the most of any scene, anywhere. The maximum sync speed is 1/250 sec, with first and second curtain shutter synchronization, plus exposure compensation support and flash value lock and even red-eye reduction flash. And to keep you from hunting for the sweet spot the next time you need to properly illuminate a scene, all your settings can be automatically saved and recalled in the unit's built-in memory.
