What kind of pixel shift results can we get out of the Sony A7R V using the Sony software and also LibRaw PixelShift2DNG? Is pixel shift now a viable option for regular use where motion is involved?
Background
Sony’s pixel shift (4-shot or 16-shot) has none of the smarts as found in the high-res multi-shot mode of the Panasonic S1R or Olympus E-M1.
