The Sony SEL55210 is a good addition to the NEX kit lens. Even if it can not keep up on the sharpness of course with a new SEL fixed focal lengths, it provides - slightly dimmed - over the entire aperture range a satisfactory sharpness. These pretty colors and beautiful bokeh. In addition, it is -despite its great length - much handier than the SEL18200. Compared to the new Tamron 18-200 mE it offers on average a much better picture quality, which is also the reason was that I have returned my Tamron again. Firstly, the AF was more accurate at the NEX5 (without N), on the other hand, the sharpness, especially at the long end, in almost all situations better. In addition, significantly fewer audio CAs. The disadvantage is of course the fact that you can carry around two lenses and this has to change. However, as I focal lengths above 55 mm only rarely use, I suppose the objective change if the higher image quality and lower price gladly accept.
