The white box flashing on the outside is the shutter indicator in ES so you know you're shooting.
So there are no videos out showing burst shooting with the mechanical shutter. Should we expect the same results.
I assume the mechanical will have blackout.
How can it not have blackout? The sensor is literally covered by a mechanical shutter and therefore cannot read anything but darkness while the shutter is closed. The only way to show anything during this would be an artificial frame.
I just mean I think it will be more pronounced than most think. The 1dx iii's is quick compared to other DSLRs, despite mirror+shutter. Mirrorless may utilize the frame insertion technique, but I'm not entirely sure?
Mirrorless cameras black out because the camera has to close the shutter and clear the data off the sensor before it can re-open the shutter to expose the sensor for the LCD or EVF to display the scene. This takes much longer than raising and lowering the mirror on a DSLR and at higher fps rates the blackout is continuous. Some mirrorless cameras disguise this by displaying the previous shot.
The sensor read time is very important to alleviate blackout time hence the Sony a9 black out free.
That's how I see it...
Even a very fast sensor readout does not prevent a physical blackout of the sensor when the mechanical shutter closes. It may have less of a blackout because the sensor array can go back to reading light faster because it cleared the data from the capture quicker than most other cameras. There is still a period of time depending on your shutter where the sensor is literally covered and cannot see. I imagine Sony does a good job masking this but it’s still present. The only way to be blackout free would be to have a completely separate sensor reading out data to the viewfinder while your main sensor is covered by a mechanical shutter.
Sony eliminates blackout on the a9xx ny using electronic shutter, on a sensor with extremely fast sensor read speeds. So far the only sensor capable of this. With mechanical shutter there is no way to avoid it.
