We have two reviews of the new 16-35mm lens:

Imaging Resource writes:

I was very impressed with the FE 16-35mm f/2.8 despite the limited time I had with it. On both the Sony A7R II and the A9 it focused extremely quickly and with pinpoint accuracy while delivering extremely sharp photos with beautiful bokeh. This is most certainly a lens to be excited about when it releases later this year.

After using the Sony 16-35 f/2.8 GM this summer in Iceland and finally getting my own copy just before I published this review, I think it is safe to say that Sony knocked it out of the park with this lens. In a relatively small light body, they managed to pack in a ton of optical quality into this lens. Not only it is incredibly sharp corner to corner, but the images that come out of this lens are simply gorgeous. Between the bokeh, contrast and texture detail…there is a lot to love.

On Amazon US, Amazon DE, Amazon UK you can find some CCTV lenses for E-mount named Pixco. If you wonder how good or bad those lenses are just check out this review from That1CameraGuy:

Since last week you can preorder the new Laowa 15mm f/20 FE lens at Venuslens.net (Click here). It’s the yet fastest wide angle lens for E-mount.

Christopher Frost just tested it:

Ken Rockwell tested the Sony 24-240mm FE lens and the conclusion is:

Get one! This lens does everything. Even better, get this lens and simply forget about any fixed-focal length lenses, macro lenses, or anything like the 24-70/2.8 GM or 70-200/2.8 GM; this lens replaces them all.

He also tested the 28mm FE lens:

This is a swell little fast wide lens for full-frame, and a swell fast normal lens on APS-C. It’s tiny, nearly weightless and works great. If you want a tiny fixed lens, here you go.

Lensrentals compared three Sony’s Ultra Wides: the Sony 16-35mm f/4 ZA, 16-35mm f/2.8 GM & 12-24mm f/4 G. They liked all three lenses:

“I cannot stress enough that we’re splitting hairs. These are all excellent lenses, and I would recommend them for different reasons to different people.”

But it’s the 16-35mm GM that really impressed them:

The Canon has been my go to since it came out, but I really believe that the Sony bests it. Sharpness? Check. Contrast? Check. Great color? Check. Check. Check. It checks all the boxes. It should go without saying at this point, but I expected greatness from this lens, and it delivered in spades in the images I got.

Adrian Murray tested the brand new Laowa 15mm f/2.0 FE lens which you can preorder since this week at Venuslens.net (Click here). The conclusion:

If you’re a landscape, astro, or architecture photographer shooting with a full frame E-mount system then I would recommend this be on your radar. It delivers fine results in a small package and a fair price. If I had to guess I think a lot of you reading this are probably comparing this lens to Sigma’s 14mm offering. Sure, you lose autofocus, 1mm and 1/3 of a stop when compared to the new Sigma 14mm f/1.8. However, this lens was built for Sony E-mount cameras so you end up getting a more nimble design. Autofocus? Really? This is 15mm, do you honestly need that? You’re not likely going to be using this lens to shoot fast moving subjects. You also gain the more manageable front element. Oh, there’s also the tiny fact that this lens costs about half that of the Sigma Art. Not to mention the weight savings. The Sigma 14mm comes in at 2.57 pounds (1170 grams), not including the weight of the adaptor which you’ll need to use it on a Sony camera. That’s over twice the weight of Laowa’s option. Either way, the Laowa is a performer and fits nicely in my camera bag.
