hedonist222 Posted July 16 Share Posted July 16 What's the fastest shutter speed for the strobe and a Sony A7Rv in HSS mode? Thank you. Link to comment Share on other sites More sharing options...
Barmaglot Posted July 16 Share Posted July 16 HSS does not have sync speed limitations, as the strobe flickers continuously at a high rate while the narrow slit between shutter blades passes across the frame, therefore you're only limited by your camera's mechanical shutter speed. For the A7RV, that's 1/8000s. However, HSS, when activated, significantly reduces the brightness of the strobe, and increasing the shutter speed progressively reduces it further. As I recall, with my Retra Pro strobes, I get a similar exposure with HSS at f/8 1/2000s as I do with normal sync at f/22 1/160s, both at max power. 1 1 Link to comment Share on other sites More sharing options...

Good explanation! Realistically, about 1/800 - 1/1000 or so for the HS-2, but you most likely wont need that fast. The biggest benefit is to help tame a sun ball or use a wider aperture beyond the 1/160-250 normal limit. 1/640 or 1/800, or less, can normally do that very well. 2 Link to comment Share on other sites More sharing options...
hedonist222 Posted July 19 Author Share Posted July 19 So using a Sony A7RV and S-turtle 2 trigger, how do I set it up in HSS mode? Balazs said no need to setup software. But there is a B.Scatter MF-2 option that I cannot select for some reason. Link to comment Share on other sites More sharing options...

It should be in the same place where you would select HSS with a land based flash. Link to comment Share on other sites More sharing options...

One must turn on wireless flash in the camera settings in order to use HSS with a Backscatter MF-2. Sample: ISO 200, 1/500, f/6.3 Link to comment Share on other sites More sharing options...
