The AD200 TTL flash kit from Godox is built around a unique flash light source that has a standard speedlite head and a bare bulb head that give you the option of two distinctly different qualities of light.
The speedlight head outputs the standard look of an on-camera flash that can be modified using an optional softbox, beauty dish or umbrella. The bare bulb head features a removable flash tube and produces 360 degrees of soft, bright, nearly shadowless light. The head uses optional reflectors that focus the beam angle and give you directional control. The AD200 has impressive core features such as 200 Ws of power adjustable in 8 steps from 1/128 to 1/1, recycling from 0.01 to 2.1 seconds. The flash runs on a removal rechargeable lithium battery that will give you up to 500 full power flashes and thousands of lower power flashes.
The AD200 has 3 flash modes: Manual, TTL, and Multi (Stroboscopic). Manual outputs the user's choice of power, modeling light, first or second curtain sync, etc. Multi controls the stroboscopic rate up to 90 times (90 Hz). TTL takes advantage of the flash head's built-in X1 receiver. Optional TTL transmitters are available for Nikon, Canon, Sony, Olympus, Panasonic and Fuji cameras. They will also detect a separately purchased LED head. The 32-channel wireless system controls flash mode, first and second curtain sync, High-speed sync up to 1/8000 sec, power level, modeling lamp and ready beeper at distances up to 328'.
