This exceptionally versatile and efficient studio flash is able to deliver lighting fast recycling times and stable output throughout the entire power range. Equipped with accurate and reliable TTL mode, this unit can be successfully used when lighting conditions are changing rapidly. The built-in Navigator X receiver allows full wireless control and triggering up to 100m. High Speed Sync is also available (up to 1/8000s).



Colour priority

The Atlas 400 Pro TTL stands out for it’s high color consistency throughout entire power output range. When high color accuracy is needed, the photographer can activate a specially designed Color Priority Mode. In this way, whatever power output is set, the flash can be triggered with the highest possible accuracy. White balance fluctuations in this mode will not exceed +/-75K. In standard mode white balance is rated as 5600 +/-200K.

Recycle time

The Flash is able to emit long bursts of precisely controlled light in both Color Mode and High-Speed Sync. When set at the maximum power, the Atlas 400 Pro TTL is ready to be triggered again after just 1.5s!

Fast as a lightning!

Atlas Pro can also be used to freeze motion of fast moving objects. It allows you to capture liquid splashes, running children or martial arts masters during training. The flash can go down to 1/ 12340s (at 1/256, t0.1) which is more than you need in most cases*.
