The SEL50F18 from Sony offers outstanding optical quality in a well-made housing at a reasonable price. It is clearly superior to the kit lens at all stops. The focus is on the whole picture spread very good, and it is mainly in the central regions knackscharf. The colors and the bokeh are outstanding. In my view, the lens with the best price-performance ratio on the NEX. Could not be recommended as Always plan due to the focal length throughout, complement an additional zoom or fixed focal length, however, a full recommendation.
