Photoreview tested the Zeiss 16-35mm lens and writes:

Subjective assessments of test shots showed the review lens to be a good performer, delivering good centre-of-field sharpness, well-resolved detail and accurate colour rendition. Quite a lot of corner softening was found at the shorter focal lengths, probably caused by curvature of field, which is not uncommon in ultra-wide-angle lenses. Stopping down largely eliminated it.However, even at the smallest aperture settings, there was high enough resolution for the lens to be useful, which makes this lens a good choice for landscape photography.

SLRgear reviewed the Sony FE 70-200mm lens:

Optically, the lens is very good and carries many of the technical bells and whistles that an enthusiast to professional photographer demands — good image stabilization and well-built construction (though we have our doubts about the lens’s purported dust and moisture resistance). But for all other avenues, the 70-200 ƒ/4 FE lens is solid choice for Sony mirrorless shooters looking for a high performance telephoto zoom.

Mirrorlessons tested the 55mm FE lens:

I think that the 55mm paired with any of the Sony A7 cameras produces a fantastic combo and I wouldn’t renounce it even now. It was also very helpful for the last wedding I shot in Italy. The only lens I could perhaps consider to replace the 55mm is the Loxia 2/50. The quality is basically the same and I really liked my time with the two Loxia lenses when I reviewed them in November last year. But there is no question that autofocus is a nice feature to have.

Many bloggers and photographers are testing the new FE lenses. Time for a new roundup:

Diglloyd is testing the new Zeiss Distagon FE 35mm lens.

A camera system needs at least one outstanding lens that makes owning that system worthwhile. Or rather, a lens that is so appealing that the camera body becomes an accessory.
Until now, that Sony A7 series platform has been a study in “good enough”. That system mediocrity ends now with the Sony/Zeiss FE 35mm f/1.4 Distagon. The question is whether lens siblings of similar quality will emerge to complete the nucleus of a complete system that demanding photographers hunger for.
Dang, where is that 50 or 80 megapixel Sony A9 with real 14-bit files?

Just a note for Digglloyd. Do not forget there is an excellent 55mm FE lens in the line up :)

Steve Huff tested the FE 28mm lens:

As for this 28mm, it is to me, a no brainer at $450. You will not find a better new production 28mm for full frame for this price, period. While not perfect due to the distortion that is present without correction or using a lens profile, it is easily overcome. Shoot JPEG and they are perfect out of the camera. Shoot RAW and you will need to apply the camera lens profile to fix the distortion, but when it is fixed the images will be gorgeous.

Amateur Photographer also tested the 28mm lens:

This 28mm lens may not be quite as optically stunning as the Zeiss-branded 55mm f/1.8 or 35mm f/2.8, but it’s still pretty sharp wide open, and once it’s stopped down to normal working apertures of, say, f/5.6 to f/11, it’s very good indeed. It’s also small and light enough to slip into your bag and carry around, where larger lenses may be left behind.

Mark Galer is testing the 90mm macro lens:

This is sharpest lens I have tested since the original 55 and 35 mm primes. It is sharp at maximum aperture and stacks up well with the 55 F1.8. I like the fact that the Focus ring, when put in Manual Focus, has definite stops and was surprised that it was not as heavy as it looks. It is well balanced lens on the A7R. Sony’s Eye AF was quick and accurate – even with such a narrow depth of field. I posted two full size JPEGs to a Flickr album so Alpha users can pixel peep.

Amateur Photographer reviewed the 24-240mm lens:

In essence, the 24-240mm has the quality of a good kit lens, but with a focal length that can’t be equalled without a significant financial, and backbreaking, investment in extra glass. Those who demand the best image quality already know the downside to travel-zoom lenses, and this Sony 24-240mm optic certainly won’t be for them, but as a travel companion I think this will form a good partnership, especially with the Alpha 7 II and its advanced image stabilisation system.
