Sigma 30mm F2.8 EX DN - recommended!

I think this is a great lens - not least in view of the really low price! I came to the Sony Nex, because I was looking for a camera that makes better pictures than the small compact cameras, but handy is when my digital SLR Monster. The 30s of Sigma on the Nex-5 I'm so zoom about on this wishful thinking. I do not rush when taking pictures, so I do not mind the slightly longer initialize the camera with this lens and the sometimes slightly longer back and forth during AF. The focus will be found safe in my experience. The quasi-manual focus also works very well, I have this possibility already used mainly at night and starfield shots often. The processing of the lens I find neat.

Now the most important thing (in my opinion): The optical performance of the 30 mm Sigma is indeed impressive - not entirely, in the corners can be seen in scenes with a high contrast some lateral color, which can not be by stopping down fix. Demo images (at medium aperture):
[...]

Conclusion: Given the price for fixed focal length lovers highly recommended, a star deduction for the chromatic aberration in the corners.

(Conclusion: The CA problem is the 19 mm lens from the same series, however, much more oppressive even when 19er sharpness performance is excellent even at f / 4, on the sidelines much better than that of 16 mm Sony Pancake, but unfortunately shows the lens. . a strong lateral chromatic aberration Really a pity, otherwise it would be - as measured by my requirements - perfect).
