HSS Support

HSS shutter speeds are available for underwater flash usage in range 1/200 ....1/4000 with Sony A6000-A6600 cameras. This Retra HSS is a Manual type HSS- in HSS strobe mode Retra flash intensity can be adjusted by the strobe knob, manually only. HSS is not supported in TTL. 

Easy In-Camera Control

UW Techinics TTL circuit is fully controllable via camera menu, and includes a special feature for M mode that adjusts flash intensity. Built-in firmware allows the photographer to use 3 variants of M mode, including both classic method and advanced methods. Advanced control allows the user to adjust underwater strobe light intensity manually via camera scale (approximately 1/64 to 1/1). In this case, the photographer does not need to operate the dial switches on the strobe body, and can just keep their hands on the housing, switch M mode and set the flash intensity via the camera controls.

TTL Accuracy

Strobe type can be easily set by onboard miniaturу 10-position rotary switch.
