If you’re after compact portable flash power then the Godox AD200Pro could be the answer.
At only $560 incl. GST for the single head kit, they represent great value as well.
An enhanced version of its predecessor, the Godox AD200Pro TTL Pocket Flash Kit is built around a unique flash source with a standard speedlight head and a bare bulb head that give you the option of two distinctly different qualities of light. The kit comes with the two heads, lithium battery, charger, and carry case.
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 AD200Pro has impressive core features such as 200Ws of power adjustable in 9 steps from 1/256 to 1/1, recycling from 0.01 to 2.1 seconds, and flash durations as short as 1/15,380 sec. 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 AD200Pro has 3 flash modes: Manual, TTL, and Multi (Stroboscopic). Manual outputs the user’s choice of power, modelling 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 X Series TTL transmitters are available for Nikon, Canon, Sony, Fujifilm, Olympus/Panasonic, and Pentax 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 second, power level, modelling lamp, and ready beeper at distances up to 100m.
