I bought this lens to be able to take photos and high quality video with my NEX 7. Before I owned SEL P 18-200 obectif but this was just too heavy and cumbersome. In addition the engine was not suitable for videos (too slow), and was audible. THE SELP18105G is a very good alternative. The videos are very well stabilized and the picture quality is perfect. The power zoom works as I had hoped and makes no noise. The size and weight are acceptable for NEX cameras. The 105 mm (157mm 35mm) are generally suficent with opening F4 on the screen 18 to 105 mm.
