Sigma 30mm F1.4 Contemporary DC DN Lens for Sony E

lobjectif joue son rôle mais il a lair moins solide que les objectifs Lumix. Par exemple, la monture est assez sensible lors de la mise en place et souvent lappareil demande à refixer lobjectif. Néanmoins, compte-tenu du prix des objectifs Lumix, ce Sigma joue bien son rôle et les images sont claires et bien définies.

If possible, I would have given this lens 7/10 but decided to err on the lower side (3 stars instead of 4) for the reasons below.

The sigma 30mm f2.8 is a compact lens designed for a future compact mirrorless by sigma, but has been ported to m4/3rds and the nex mount. The 30mm translates to 45mm in 35mm terms, which gives us an almost normal focal length. Along with the 19mm, Sigma has created the first third party autofocus primes for mirrorless systems. Neat! The lens is compact in size (about the size of my 50mm 1.7 Minolta AF lens), and the front element is VERY small. The back element is large, allowing for a small design with minimal distortion and good coverage across the frame. The most important features of this lens are the focal length, and size. 50mm is often the most desired focal length in a system, which is 35mm in APS-C terms. Since the NEX system has large amounts of adaptable glass, this would seemingly be non-issue. But 35mm lenses are large for film cameras, due to retrofocus designs. Often the adapter and 35mm lens combination would leave you with a very long lens, and fast aperture (as in f2) 35mm lenses are even bigger. The only convenient options in terms of size available until this lens were the 35mm f1.7 CCTV lens (which has unbearable corner performance and vignetting, though a good lens if used stopped down marginally and centralized composition), the Contax G 35mm f2 (hard to come by, and the adapters are expensive, and lastly the Voigtlander 35mm 1.4 (very good lens, small with great construction, but expensive). So this lens represents something pretty significant, especially considering the autofocus capabilities.

Product is great but the price was $100 higher than Walmart.

really good lens! makes me want to return the18-105 f4.

Una Optica impresionante por su nitidez y luminosidad , un sueño poder tener un f 1.4 de esta calidad a un precio tan contenido

Great starter lens for starters!

I was surprised to find that Sigma had introduced some Micro Four Thirds lenses and after reading the reviews I bought this one. The quality is very good especially at this price. Image quality is at least on a par with the 20mm Lumix pancake lens I also have, which is much more expensive. The Sigma probably has the better focal length for use as a prime lens. Highly recommend.

Lo he probado tanto en mi sony a6600 como en la NEX-5T, y la distorsión es terrible… para fotografía donde la geometría sea importante es sencillamente inservible. Y compararlo con el sel24f18z un insulto.
