I'm looking at adding a mid range zoom to my m4/3 kit. As I'm using Panasonic bodies, I'd like to get a lens fitted with IS that probably restricts me to either:- P45-150 P45-175 P45-200 Optically, the P45-175 seems to be rated most highly, but it is the most expensive and has the spectre of it's much discussed blurring over mid range shutter speeds hanging over it. Is this still an issue with the newer bodies such as the G6? The 45-200 is relatively large and has a mixed reputation at the long end. The P45-150 seems to get some very good user feedback, but on paper is also weak at the long end. So, I would be grateful for your thoughts, especially from those who are using any of these lenses on Panasonic bodies. I will be using them for stills, not video. Thanks in advance. Simon.
