I'm considering whether to get the Profoto Air Remote for the a9 or stick to shooting Canon with Profoto strobes. How is the a9 with mechanical shutter and strobes? I see when on mechanical shutter the evf is pretty laggy...Anyone using Sony a9 with Profoto B1 or D2? Good or bad?
I think you are perhaps confusing/combining sensor readout, EVF lag time, EVF refresh rate.
The EVF refresh rate - meaning how may times per second the electronic viewfinder refreshes itself, does not change whether you use the mechanical shutter or electronic shutter.
There is a lag, even with the best EVFs on the market like on the A9 and Leica Q, that is noticeable on fast moving subjects. Again though, this occurs regardless of whether you are using strobes, continuous lighting, or available light. Again, this lag has no relation to whether you are using a mechanical shutter versus an electronic shutter - also moot point as you of course cannot use strobes with the electronic shutter.
So in other words, this is not a challenge with the strobe (and getting a B1 or D2 won't help resolve it), it's a limitation of current EVF technology. I personally prefer to shoot with an OVF when using strobes primarily because the WYSIWYG aspect of an EVF is moot when using off camera lighting.
