I have this on my Sony Nex Universal Zoom 6, and am extremely happy with it. Since traveling the full range (27-159mm Kb) covers me I need that continuous maximum aperture of 4.0, I find extremely pleasant because in low light autofocus at 105 mm very good works. Unlike the 18-200 where I already have Aperture 6.2 as open aperture at the 200mm. I can therefore find the resolution sharpness and colors with this lens fully meet my expectations so in my opinion are very good. As a small defect I see this lens on 70mm diameter of the front lens on the NEX 6 very voluminous works but it will probably be no different technically solvable. Sony delivers at that 3-year warranty for free. Among the mentioned by other komentaren distortions, it is eaten right lens in shutdown of all corrections, but I I own some cameras even when others try and have found that consume all calculated on APS sensors lenses without-camera correction there.
Addendum: After three months and two trips with approximately three thousand shots, I forgive the lens and the 5 star, because it produces what resolution and color concerns truly outstanding pictures, and the autofocus with the new Alpha 6000 reacts rapidly with it.
