So I'm very happy with the lens. After switching on the camera the lens is for 1 sec Ready. Even after turning off the retraction takes only 1 sec. The autofocus is faster than the 1855th The pictures are just great. The best is the Power Zoom. Here you can not go wrong. Finally the Nex fits in your hand or pocket. Addendum of 12/08/2013. I purchased the lens with a Nex 3NL in the kit. The price of 300 was just too tempting. At my old Nex 5 shadows could be seen at the edge of the 4 corners, the 16 mm range. In the non-18mm range. At the Nex-3NL that is fixed to the internal camera's automatic, and the chromatic aberration. In Jpeg anyway. ARW I have not yet tested. In combination with the Nex 3NL one has a nice compact camera. The pictures are just in poor conditions very well. (Hand-held Twilight) is awesome. In warm weather also makes a great compact camera images. Unfortunately, we usually have a Cloudy Sky. I made a few pictures today in very bad conditions. In the afternoon at the Christmas market. It is quite hazy and gloomy. I find for private use, this camera is ideal. A press photographer takes as something quite different. I write this from experience. On YT user Theschnuckel I have a lot of pictures (video) set. Most with the NEX-3 NEX-5 se1855 sel1650. There you can see what is possible with these Nexen. Have Fun
