CameraLabs finalized his A7rV review and concluded:

By becoming more practical for long exposures, macro photography and pixel-shift composites, the R V broadens its appeal, while also giving you the flexibility of a tilt and flip screen, the joy of the most detailed viewfinder around, the bonus of 8k video and Sony’s most cunning AF system to date. I can definitely recommend it, but whether it’s worth the extra thousand? Only you can say.

One more review from Sidney:

SonyAlphaBlog reviewed the new lens and concluded:

The AstrHori 12mm F2.8 Fisheye (259$ / 349 euros) is a very good Full frame fisheye lens. Its is build like a tank , its ergonomic are very good (nice click aperture ring and well dampened focusing ring).

Its performance are very good overall with very good sharpness on the entire field as of F8, very good color rendition, nice background blur, very good resitance to flare. Its only weaknesses are the sharpness in the corners between F2.8 to F5.6 being only good on 61Mpix, and the sunstars that could be better defined
