I was so impressed by the Panasonic G5s performance I wanted to try a longer focal length lens on it of a more modern design. This is one on Panasonics newest lenses, doesn't cost an arm and a leg and fits in great with the 14-45 kit lens which I still use. It's one of the best kit lenses on the market today (much much better than the 14-42 which they have). It's small light and feels well built.
I have to say right off that this lens is a GOOD LIGHT lens, no doubt about it. Although facusing was ok in dark or poor lighting it did make a difference when using it it in good light.
