'The Sigma 30mm the best of all available E-mount lenses?'

Re: In context, yes ...

The Sigma is a surprisingly well performing and affordable gem.

But the test is only concerned with lens sharpness. All lenses produced use-able sharpness when stopped down, whereas the Sigma produces impressive, best, sharpness even wide open.

It is impressive to see a 30mm low cost prime outperforming a Leica 50mm.

But not all lenses are 30mm FL, some lenses are faster than f/2.8, some lenses need OSS (video?) and then, the zoom lenses fall into a different category alltogether.

I agree, especially on a Nex-7, the Sigma produces impressive pixel level sharpness.

But if your need is monitor size images, modest print size images, many lenses work quite well on the Nex/Nex-7.

I think that both Sigmas represent an additional lens that everyone should seriously consider adding to their lensbag.

I don't think that it should be the only lens. I am traveling with (only) the two Sigma's right now, and, with (family) people shots, I actually miss f/2.0, zoom, and OSS. There are certain shots (and videos) that do come out better with the other lenses.

But I appreciate the compactness. A two-lens sigma 21/30 bag is smaller than a two-lens Sony 24/50 bag, and the difference is enough for me to sway my decision.

That's the question sonyalpharumours poses after reading Lensrentals result after measuring the resolution of all currently available NEX lenses including a Leica 50mm f/1.4 Summilux with Fotodiox adapter. At f2.8 and f4.0 the Sigma 30mm is the winner. To quote Lensrentals: “The Sigma is really amazing. Obviously it’s not really a wide aperture prime, with a maximum aperture of f/2.8, but it gives world-class resolution. The Sony 24mm f/1.8 is not the bargain the Sigma is, but from f/2.2 on it has amazing center resolution, although it lags behind the other two in the corners.”
