I understand that the e-shutter can have speeds up to 1/6000 sec. But at the same time it has a 'long readout time' that induces rolling shutter effects.
My understanding of this effect is based on the following math:
The sensor is 11656 x 8742 pixels. So it exposes11656 pixels in the first row and then moves to the next row.
But it has to read out the first row before doing this otherwise the exposure of the first row will increase as it exposes the second row. Since there are 8742 rows, it would take 8742/6000 = 1.457 seconds to read out the whole sensor at 1/6000 sec. Right?
So an exposure of 1/60 sec would result in a readout time of 100 x 8742/6000 = 145.7 seconds = 2.4 minutes?
Let me help you. Don't use eshutter on the X2D2. Pretend it's not even an option. Move on, smell a flower, watch a good standup special. Life will improve.
The X2D2's read out speed is 144ms in 14bit, and more than doubles (370ms) for 16bit according to Hassy. Those don't change regardless of your settings.
1/6000 is per pixel exposure. For each row read out time, you can use their published or from internet to find whole frame read out time.
For example: if read out speed is 1/4S at 16bit and 1/10S at 14bit. ( this is the GFX 100M sensor spec I know)
Then per row read out will be 1/4/(total rows of sensor).
