Dpreview posted the final Nikon Z7 review. And overall recommends the Sony A7rIII compared to the new camera:

The most obvious and direct comparison on the mirrorless side is the Sony a7R III, another camera we hold in extremely high esteem. And the similarities between these two cameras are remarkable; spec for spec, they nearly mirror one another. But the Sony is a third-generation product, while the Nikon is a first, and it shows. While there are things we prefer about the Nikon (like more sensible menus, better operational responsiveness and a more comfortable grip), in terms of raw performance the a7R III manages at least match it in everything from Raw dynamic range, to video quality, to AF reliability. We also love Sony’s Eye AF. These differences aren’t huge, but overall, the a7R III will likely be the more capable option for most users.

Just an additional note: I keep reading that Nikon had it hard because it’s their first generation of mirrorless cameras. But I never heard the counter argument that in many aspects they actually had a much “easier” job to do than Sony. They knew in advance what they were competiting with, they knew in advance what people like and disliked from Sony cameras. To me this must balance the “first generation” argument. Sony had to figure out everything all alone in these years…

Photographyblog posted the full Zeiss Batis 40mm FE lens review:

The Zeiss Batis 40mm f/2 is an outstanding short-standard prime lens. The novel 40mm focal length takes a little while to get used to, falling as it does between the more “normal” 35mm and 50mm focal lengths, but it quickly loses any real significance after you’ve used it for a while.

Sharpness is very high across the frame. Even with our A7R II test camera recording 42-megapixel images, detail is exceptionally sharp. Shooting at the maximum f/2 aperture does reveal a minor reduction in sharpness, but this is already resolved by f/2.8, and even at this aperture the lens is able to produce beautifully smooth bokeh.

Some vignetting is apparent when shooting wide-open at f/2, but quickly disappears as you stop down, while chromatic aberrations, distortion and flare are all very well controlled, and the bokeh is very appealing for this type of lens. The 24cm minimum focusing distance and 1:3.3 magnification ratio makes the lens versatile enough to shoot close subjects.

The Zeiss Batis 40mm f/2 proved to be a pleasure to use, thanks to its superb build quality, smooth focusing ring and innovative OLED display. When manually focusing, together with the A7R II’s excellent Peaking feature, the Zeiss Batis 40mm f/2 delivered a very high percentage of keepers, and it also proved to be very quick, quiet and accurate when auto-focusing.

There’s only one real drawback to the Zeiss Batis 40mm f/2 lens – the asking price. £1129.99 / $1299.99 / €1,299 is a lot of money to pay for a standard prime lens, even one as well featured and built as this.
