Sony FE 12-24mm test at Photozone: “the Sony is a no-brainer. Highly recommended!”

Photozone tested the new Sony 12-24mm FE lens:

Upon first contact, you will notice how small it is compared to similar (DSLR-)offerings. It’s even more obvious in term of weight (565g vs 1150g for the Sigma 12-24mm f/4 HSM ART). Now you may expect that this comes with a couple of compromises but there are actually only a few. 
If ultra-wide perspectives are simply your thing then the Sony is a no-brainer. Highly recommended!

And Photographyblog tested the 16-35mm GM:

It delivers outstanding sharpness in the centre of the frame throughout the full aperture and zoom range, and also performs excellently at the edges of the frame too. The Sony FE 16-35mm F2.8 GM lens does suffer from some distortion and vignetting, but chromatic aberrations are very well-controlled and it can even create some nice bokeh effects when shooting wide-open at 35mm thanks to the rounded 11-blade aperture. The Sony FE 16-35mm F2.8 GM offered pleasingly fast, quiet and reliable auto-focusing on the A7R II that we tested it with, intuitive manual focusing and great build quality, plus it’s usefully weather-tight too.
Overall, the Sony FE 16-35mm F2.8 GM is the newest and best wide-angle zoom for Sony full-frame shooters with deep pockets…
