This universal single-contact shoe-mounted flash runs on four AA batteries, which will provide up to 400 full-power flashes with a recycle time of 1.8 seconds.
Flexible Lighting Control
The flash head tilts from -7 to 120°, rotates horizontally 0 to 330°, and incorporates a bounce card and flip-out diffuser.
In Manual mode, the flash provides 8 power settings from 1/128 to 1/1 in ±1/3-stop increments.
The flash can be triggered by hotshoe, the included RT transmitter, S1/S2 optical sync, or the PC sync port.
With the separately sold S-R1/S-R2 and S/S2 adapters, a variety of accessories can be mounted.
Multiple Power Options
The internal battery compartment accepts 4 AA NiMH batteries, saving you from ever having to recharge the flash before use.
For shorter recycle times and higher flash counts, the TT520III can be connected to the optional PB960 power box
