Further readings for the Sony FE Carl Zeiss Sonnar T* 35mm F2.8 ZA
To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.
Last month’s launch of six new FE mount lenses is great news for Sony enthusiasts shooting with A7 cameras. With only a modest number of FE lenses available until now, the new lenses — including two wide-angle primes, two ultra-wide angle converters, a close-focus macro and versatile superzoom — open up more possibilities on Sony full-frame hybrids. They’ve kept us busy in the lab, too, and the scores are in and verified for the FE 28mm F2.
We’ve tested the image quality of the 24-Mpix Sony A6000 with over 23 zoom and prime lenses. Read on to find out which of those models perform best with Sony’s current top-of-the-line APS-C mirrorless model.
Utilising a 16Mp APS-C sensor, the Leica T is the first mirrorless hybrid option from the renowned German camera manufacturer. With a price tag of $1850 (body only), and lenses costing the same or more, it’s a serious investment for any photographer. So how does image quality on the Leica T stack up against the competition? Let’s analyze the DxOMark sensor scores to find out.
Sony has expanded its range of full-frame mirrorless cameras with the launch of the Sony A7S. Joining the Sony A7 and A7R, the new A7S offers a lower resolution 12.2Mp sensor with an ISO 50–409,600 sensitivity range, and breaks boundaries for video with its 4K/30p video footage output.
Continuing our series of lens recommendations for new camera models, we’ve had the opportunity to assess the new entry-level Sony A3000 - the first of a new DSLR form-factor from the firm to adopt the mirrorless E-mount. We’ve assessed and collated data on a sizeable collection of Sony and third-party prime and zoom models to assess image quality. Read onto find out which of these models perform best when paired with the new camera.
The Zeiss Sonnar T* FE 35mm f2.8 is a compact moderate wide-angle lens designed for the full-frame mirrorless Sony Alpha A7 and A7R. But with only a moderate-speed f2.8 maximum aperture and an $800 price tag, optical performance has to be first rate. Read on to find out if that’s the case.
Sony Zeiss 35 & 55mm FE lenses vs Sigma 35mm f1.4
<div id="linkdxomark">This a comment for <a href="http://www.dxomark.com/Lenses/Sony/Sony-FE-Carl-Zeiss-Sonnar-T-STAR-35mm-F28">this page on the website</a></div>Thank you DXO for a very useful test. I currently have the Sigma 35mm 1.4, albeit on a Canon 5D2, and it's a real joy to use. It's my favourite lens. I will buy the much smaller and lighter Sony A7R but to do so I will have to sell my lovely Sigma and the Canon 5D2 plus more Nikon cameras and lenses. The report has convinced me that although the Sony Zeiss 35mm 2.8 is not quite as good as the Sigma 35mm, although it is nearly as sharp as the lovely Sigma, it fulfils the brief to keep my equipment small and light (120 gms vs 665 gms lenses only!). I enjoy working with a tiltable screen on a tripod as most light tripods don't reach my eye level. The Sony Zeiss lenses are weatherproof too. On my wish list will be the Sony Zeiss 55mm 1.8 and who knows, maybe later the Sigma 35mm 1.4 for special occasions! Thanks again for a very helpful report.
I have the a7 with the 35 u've tested and have never had a sharper combo. The vignetting u report in your test data is something I've never experienced. I can't even imagine anything from Sigma being an equal. Test data can show many difference results. I prefer the real thing. Choose your camera and shoot. I'll keep mine. Looking fwd to the 55 next yr.
If you compare the A7(R) with and without AA to the D800(E) with and without AA it is likely that the A7 with this lens will score 30-31 overall and 19-20 P-MP.
Notice that the Carl Zeiss 55 does not take advantage of the very short A7(R) flange distance but instead creates more reasonable angles of incidents performing much better in the corners than the 35 mm lens.
The big question. Even though Sony made the mistake to overly compress the flange distance on the A7(r) with subsequent compromise in corner IQ, the performance of the A7R with the Sony FE Carl Zeiss Sonnar T* 35mm F2.8 ZA lens will be a cornerstone in determining the near future of mirrorless cameras. Please, DxO, we are turning to you for an answer to that question !
