The three lenses do have about the same length. So which one would you get? I think in terms of price-quality balance the Sigma wins. The Zeiss on the other hand gives you a nice aperture ring and probably a tiny better AF performance. If you are on budget you save the Samyang just got a discount making it by far the cheapest of the the three.

Cinema5D checked if the new camera is any good for Vloggers:

The Sony RX100 VI is a truly compact camera, baring nice features, like the 200mm ultra zoom and tilted screen. But with a price tag of $1200 and very limited audio capabilities, I cannot see many Vloggers using it. In my opinion, it is very much of an “Engineering product” and not a “User product”, meaning, it is clearly a product that wants to be noticed but on the expense of usability. If the video functionality of this camera is important to Sony – especially as it is being marketed to Vloggers – I do hope that they will take some notes and try to improve the usability and functionality of the related video functions in the next generation, hopefully.

Nino Rakichevich tested it shortly for Alphauniverse:

I only had a chance to use the camera for about a week, but after shooting with it on the streets of New York and Los Angeles, I’m planning on buying one and adding it to my bag as soon as I can. Here are some of my favorite photos from my days shooting with the new Sony RX100 VI.

Should you buy one? In many ways this is one of the best compact cameras out there – certainly, when it comes to performance there’s nothing else that can touch it, while the images from the 20.1-inch sensor are excellent. But the RX100 VI’s strength is also its weakness, with some of the tech that’s on tap – and which you’re paying a premium for – feeling a little like a sledgehammer for cracking nuts.

The new Tamron 28-75mm F2.8 Di III RXD isn’t the best standard zoom lens for Sony full-frame mirrorless cameras in terms of outright image quality, performance and build quality, but it is currently the best lens in terms of its cost to performance ratio, offering a lot of bang for not a lot of buck.
In summary, there’s a lot to like about the Tamron 28-75mm F2.8 Di III RXD and not a lot to loathe.

CameraSize added the new Sigma 24mm ART lens and Samyang 24mm pancake in their CameraSize comparison tool. That Sigma lens is a beast in terms of size!

Alan Dyer (article here) shared a good news. He tested the new A7III for Astrophotography and the conclusion is:

“The Star Eater is gone. Stars are not smoothed out in long exposures.”

UPDATE: Jim Kasson has just started testing the A7III spatial filtering. And while there is no final conclusion yet it looks like the A7III may has not fixed this issue once and for all:

There was a recent posting to the effect that the spatial filtering (aka “Star Eater”) present in many a7x cameras and firmware releases at shutter speeds of longer than 3.2 seconds has been “fixed” in the a7III. The spatial filtering is different, but it has not disappeared.

This means we have to hold off and wait until Jim has made the complete testing.
