I bought a Panasonic 12-60mm lens last week and have been itching to try it. The reviews were not that good, mostly saying it was a bit soft and the edges weren't all that. However, I found it really nice to use and it's so light it goes with the G5 very nicely indeed. I have to say I was a bit concerned re quality, but was pleasantly surprised at the results when I looked at the pics on the computer. Good enough for me anyway. Here's just a couple.
