I bought this lens for a trip to China. I wanted to change any lenses, so this had to be rounder. From the quality of the lens, I am, like the previous speakers, is also convinced. What did surprise me, however, was the weight. Thus, the camera is then but quite heavy and clunky. Interestingly, the new even lighter than its predecessor. But as I have already written in the title, quality has its weight. Until then I had a PZ 175. 45.- which was significantly lighter and more compact. But maybe not as bright and with reduced usability that there is no wide-angle range. Apart from the weight of this lens makes everything better.
