Not so hot
Crutchfield Customer Review (What's this?)
I had read reviews which said that this lens is soft at the long end. I have quite a few Panasonic Lumix lenses and have never gotten a bad one...until this lens. It is soft at the 42 (84mm) end. It seems that it is the luck of the draw with these as some units are sharp from end to end. Unfortunately, I got a bad one. UPDATED 2/29: I am not all that nuts about the focusing method of the new lenses, but they are optimized for the video function and not still photos. After testing the lens I would be inclined to recommend it to a friend.
Pros: Size and weight. Makes a good travel lens.
Cons: So far I have none.
