Price / performance hammer!

I agree with previous speakers only, although I was a bit skeptical because I with the kit lens a few focus issues had (back or front focus), and unlike my Sigma, the colors were not quite as strong.
Nevertheless, I have decided because of the good reviews, and the good test results on the net for the SAL 50 F18, since I have yet to read anything negative about it and I do not regret it completely.
I think you will find this small price nothing like it for its Sony DSLR.

Have previously photographed exclusively with my Sigma 18-200 3.5-6.3.
That the imaging services are a little better, was expected to see, but that they are so good, my expectations surpassed yet.
The lens is really at maximum aperture very sharp, even yet, slightly dimmed at the edges even more sharply.
What I've always missed something in my Sigma, was a soft, quiet Bokeh, which is to reach there due to the movable lens groups by the Megazoom course a bit more complicated.
All the more I convinced Sony. So a Bokeh I wish. Very soft and quiet, so that the focus really depends on the anfokussierte object and not the background.
So it's perfect for highlighting useful, which is why it's also a portrait lens.
Likewise, one gets here, even with cloudy skies extremely fast shutter speed at ISO 400 out.
Vignetting and fringing is almost imperceptible. The latter just a bissel, at outshone edges, but this seam is so low that he even increased relatively strongly only extremely low strikes.

So thumbs up and a buy recommendation on each, because even despite the small price, it can also use large and super photographer take pictures with it and for the price there are certainly no better.
So my skepticism of Sony lenses is completely dispelled, and I am very happy because I had such a superior performance for this price do not expect.
