Lenstip is one of the best review sites you can find. And they just tested the new 16mm f/1.4 E-mount lens:
The Sigma C 16 mm f/1.4 DC DN is not a flawless device; especially in the area close to f/1.4 you can find several distinct shortcomings. Still you have to remember that those shortcomings disappear on slight stopping down of the aperture and image quality improves very quickly too. As a result this lens’s resolution levels are close to record values on both types of sensors and we mean here records achieved by lenses several times more expensive than the tested one.
Pros:
good quality casing,
sensational image quality in the frame centre,
sensible resolution on the edge of the frame,
slight lateral chromatic aberration,
moderate vignetting,
nice out-of-focus areas,
silent and fast autofocus,
good price quality ratio.
Cons:
a bit too high longitudinal chromatic aberration,
not completely corrected spherical aberration,
too high distortion,
coma visible in the corners of both types of detectors,

Sony A7rIII review at CameraJabber.
James: “We shot about half of this film with the Sony a7RIII. I used the 24-70 GM (tripod shots) and 12-24 (gimbal shots). It’s part of the Uber 90-Second Film Fest. If you like it please like it (thumbs up button) because that’s how they’re judging. https://www.youtube.com/watch?v=w22Jca4Z4Cw We’re out of Portland, Oregon. Arya of DocuCreative wrote, produced, and directed the film.”
Chris: “I wanted to share a video of why I use the Sony a6500, I love the camera and I hope other people fall in love with Sony Camera as I have. Why I Use The Sony a6500 https://youtu.be/9Ps7kWLbPug”
Josef: “I’ve bought this lens as well and I have to agree with this video. Even when you update the latest FW on camera and the 2.0 fw version on the lens it just focuses like shit. For me this is oon of the biggest drawback I had since I switched to sony. I was seriously reconsidering my choice to jump. https://www.youtube.com/watch?v=_2iI_m9ny1Y“
