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.
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.
We’ve analyzed the image quality of the 20-Mpix Sony A5000 with over 22 zooms and primes. Read on to find out which of those models you should be using with Sony’s smallest and lightest mirrorless model.
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.
Sigma’s range of DN A lenses have been designed for mirrorless cameras using both MFT and APS-C sensors, albeit with different mounts. As the equivalent to a 45mm on an APS-C camera we’ve tested the 30mm f2.8 on the discerning Sony NEX-7. Read on to find out how well it performs.
The Swedish vendor Cyberphoto makes excellent real use reviews of cameras and lenses. Well before DxoMark's review, they found that the Art version was noticeably softer in the corners than the previous EX DN version. http://www.cyberphoto.se/info.php?article=si30mmnex
I don't believe to this test! The new Art version of Sigma has absolutely the same optical design as the old version. The old version was tested by Dxomark and got 12-Mpix of sharpness where is the new version by Dxomark gets only 10-Mpix of sharpness. I suppose that there is a mistake or the copy of the new lens which was tested by Dxomark was defective.

Thanks for your feedback, here is the comparison: http://www.dxomark.com/Lenses/Compare/Side-by-side/Sigma-30mm-F28-EX-DN-Sony-E-on-Sony-NEX-7-versus-Sigma-30mm-F28-DN-A-Sony-E-on-Sony-NEX-7___828_736_1102_0 The 2 lenses are very close, a slight difference is noticed on sharpness measurement: the new version is slightly less sharp in the corner. Results are very close, and should not impact the final image quality.
