The A1 spec that surprised me a bit was the fact that the electronic shutter curtains move 1.5x faster even though there are 1.44x as many rows. That means the sensor rows are being read out 2.16X faster. We know the A9 reads out rows in groups of 16, so is the A1 being read out in larger groups to an even larger bank of ADCs, or are the ADCs running faster. It will be interesting to see once we can make some measurements on the camera, but my guess is the rows are still read out in groups of 16 and the electronics is over twice as fast.
I think the power of Sony's fast electronic curtains is not appreciated as much as it should be. The A9 electronic shutter was already impressive and far ahead of the competition, and the A1 has significantly widened that gap.
