The Strato TTL Trigger Set for Nikon from Phottix allows remote triggering of your off-camera flash while maintaining TTL exposure control with your camera. The set contains a Strato transmitter and receiver, shutter cables, USB cable, lanyards, and a 1/4" adapter.

Running on the 2.4GHz frequency, the transmitter has an LCD display and quick-change buttons to make changing setting changes. TTL adjustments can be made on the transmitter but the system also supports in-camera flash adjustments such as exposure compensation. High Speed Sync is also supported with shutter speeds up to 1/8000 sec. The Strato has a range of 328' and since it's a radio signal, it operates through walls and around obstructions. Choice of 4 discrete channels minimize the possibility of interference. The Strato is also effective triggering manual flash units and the inclusion of shutter cables for Nikon allow you to trigger your camera remotely using the transmitter like a long wireless "cable release." The Strato system is future-proof, too. The inclusion of a USB cable allows firmware updates as the features evolve.
