I am perplexed!
Sony has been listening to the feedback surrounding the A6300 and A6500, which had quite a severe rolling shutter (30ms+) in 4K.
They have just announced a new high resolution 31MP (over 6K) APS-C / Super 35mm sensor with a global shutter.
I’m surprised at how nice the quality is from APS-C (Super 35mm) mode on the A7S. I expected it to be a lot softer! There’s no signs of significant moire or aliasing either.
The smaller window from the sensor allows the shutter to expose the whole pixel readout more quickly than in full frame 12MP mode, so less jello for us.
One of the enigmas emerging from the A7S is whether you can shoot 4K in APS-C crop mode as well. APS-C is Super 35mm in cinema language. I really would like to use my Cooke S4i Minis via a PL adapter on this camera! Taking advantage of the low light sensitivity. APS-C crop mode would also allow the use of standard Sony E-mount / NEX lenses, Canon EF-S and Nikon DX lenses.
Sony’s information (above) implies that is the case with “both resolutions available at both full frame and APS-C size”.
I dug a little deeper to find out more…
I’ll start this review with a parable. It is a parable about an old man, who fell asleep…
