Colby Brown reviewed the new Sony 12-24mm lens and wrote:
For an ultra-wide angle lens, it offers both great IQ and near corner to corner sharpness. Distortion is very minimual and the sunstar is definitely a step up above the 16-35 f/4 (that I am now retiring). Lastly, astro photographers will be happy with both COMA and astigmatism, especially if they pair this lens with the a7S II that can easily handly pumping up the ISO to counter for the fact that this is an f/4 lens.
