Batis 18mm FE lens at [shopcountry 56821].

The very sever folks of Photozone tested the new Zeiss Batis 18mm f/2.8 lens. And there is good news:

The Zeiss Batis 18mm f/2.8 is an excellent ultra-wide prime lens. Most of the image frame is already very sharp at fully open aperture although there is a bit of softness in the far corners. The corner softness is gone at f/4. The range between f/4 and f/5.6 is also the sweet spot where the quality is truly outstanding for a lens in this class. It may be a little surprising but you should stick to f/8 (if possible) instead of f/11 for the best quality in infinity DoF scenes because diffraction is a limiting factor already. Very low lateral CAs and marginal field curvature also contribute to the very high quality. Image distortions aren’t overly pronounced but complex (mustache-style). In critical situations you may prefer to enable image auto-correction for this. That also applies to vignetting which is on the very high side (typical for Zeiss). A real differentiator is the flare resistance. You can, of course, produce a few ghostings if you push it but the Zeiss is about as good as it gets in terms of contra-light performance in this segment.
The build quality is up to professional standards – a metal body, no wobbly parts, weather sealing – but at this price level we expected no less, of course. That being said, we are not a big fan of the slippery surface coating and the dismal quality of the lens cap. The AF speed is good albeit not extremely fast but that’s perfectly fine given the typical usage patterns with such a lens. Zeiss is quite proud of the new OLED display which shows you the focus distance and depth-of-field. Yes, it’s nice, it’s cool but the real killer argument is the image quality.

So should you buy one? We’ll do some more testing of ultra-wide lenses soon but we’d be surprised to see a lens that could outperform this Zeiss lens – therefore highly recommended!

Well done Tamron ehm… Zeiss!

Marc Alhadeff posted his full Sony 16-35mm f/2.8 GM review. The conclusion:

The new Sony FE 16-35 F2.8 GM is a jewel that will be a must have for all landscape and architecture photographers
Its build quality is very  good , very light to handle , very fast and reliable AF
Compared to the FE 16-35 F4 Zeiss , quality is the center is roughly the same but borders and corners are way better
Using it at F2.8 is a pleasure with very nice 3D effect and beautiful blurry background, but sometimes quite nervous
So it is worth 2 times the 16-35 F4 Zeiss? With the added F2.8 creative possibility and very high quality of borders / corners : Yes

DxO tested the new Sony 100-400mm GM lens and has only good words to spend for it:

Sony’s longest lens in the lineup, the Sony FE 100-400mm F4.5-5.6 GM OSS performs exceptionally well, especially given that it’s a tele-zoom. It has very high levels of sharpness, low fringing and vignetting, all helping it achieve a high DxOMark score. In terms of optical performance, it outperforms the popular Sigma 120-400mm F4.5-5.6 and the Canon EF 100-400mm 4.5-5.6L IS II, and ranks alongside a couple of the pro favorites — the Sigma 120-300mm F2.8 EX DG on the Nikon 800E, and the much pricier Canon EF 200-400mm F4L IS USM. It’s even not far behind the latest iteration of the Sigma 120-300mm F2.8 (the DG OS HSM S model). More interestingly perhaps, in terms of sharpness levels, it outperforms them all, even those mounted on the Canon EOS 5Ds R with its higher pixel count sensor.

Sony’s new FE 100-400mm F4.5-5.6 GM OSS stands out not only for its seismic shift in sharpness, but also for being not much different in size to the FE 70-200mm F2.8. Best of all, perhaps, is that for once there’s a tele-zoom that offers seriously impressive image quality at that prized 400mm focal length.
