Cin D says that in video mode, turning off dual gain cuts rolling shutter in 1/2 to 7.5ms:

Does anyone know if there will be a way to turn off dual gain for photos? If so, I wonder if it would speed up readout time too. 8ms would still be about 2x as slow as the a1, but would be a lot more useful than a 20ms redout for moving subjects. Then, depending on our subject, we can decide if we want better dynamic range or readout times.


If it is the same as the A7V then DGO is only available when shooting Mechanical Shutter. So in ES it should be "off".

I still believe that the shutter read is going to be half of the reported 20ms when you use the camera in Lossy Compressed RAW and ES. The A7RIV/V was twice as fast in Lossy Compressed.

So 10ms. If that turns out to be true then rolling shutter won't be much of a concern for birds. Not sure about sports?

Post edited to correct the numbers.

I still believe that the shutter read is going to be half of the reported 1/20s when you use the camera in Lossy Compressed RAW and ES. The A7RIV/V was twice as fast in Lossy Compressed.

So 1/10s or 10ms. If that turns out to be true then rolling shutter won't be much of a concern for birds. Not sure about sports?
