If you are in the market for a small flashgun to complement your Sony mirrorless camera, look no further than the Godox TT350S. At 200g it makes lugging around the flashgun for my Cosplay shots more comfortable and less imposing. I find the guide number of 36 (m, ISO 100 @105mm) great as a fill-in synchro-sunlight flash.
Capable of HSS (high-speed sync) at the press of a button, it is just ideal for off-flash photography when synchronised with the Godox X1T-S 2.4G Wireless TTL Flash Transmitter. In fact the TTL350S worked so well with the transmitter, I got myself a second unit!
Even as a stand-alone flash hooked to my Sony A7RIII, it worked like clockwork - accurate TTL (through the lens) metering, HSS and manual settings with recycling times around 1-2 seconds.
Together with my 24-70GM lens, the coverage of the TT350S is just perfect - from 24mm to 105mm. One fresh pair of 2500mAH Nickel-Metal Hydride batteries lasts around 200 shots.
