Surprise! Is the Sigma 30mm the best of all available E-mount lenses?

You ever wanted to know which one is the best lens to use on a [shoplink 8454]Sony NEX-7[/shoplink]? Lensrentals (Click here) posted a complete unexpected test result. He measured the resolution of all currently available NEX lenses including a Leica 50mm f/1.4 Summilux with Fotodiox adapter. And at f/2.8 and f/4.0 aperture there is a super unexpected winner….the Sigma 30mm f/2.8 lens which costs $199 only (at Amazon).
Lensrentals writes: “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.”

Damn, that is such a surprise! I hope Klaus at Photozone will ahve the chance to confirm these results soon! Meantime I give you the links to the two Sigma lenses:
