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.
