With dedicated off-camera flashes already available from Yongnuo, LumoPro and Godox/Brilliant, surely one more company in the market can’t hurt? The new SmartFlash US92 from Phoenix packs in plenty of Strobisty features at a retail price tag of under US$100.

The SmartFlash US92 is manufactured by Tumax and has a similar-looking head to the LumoPro LP160, although the zoom positions (if any) are not specified in the product description. It also features Full to 1/16 power in whole stops (excluding 1/2 power for some reason) and an intelligent optical slave which can be calibrated to your system’s pre-flashes. The back panel features a guide number table to help you estimate exposure settings.
