So far I am pleased I did not expect anything more than a nice kit lens and for the most part it has exceeded my expectations. Plus my wife got a mint one for $217 for my birthday not bad I wanted 12mm I got it and I wanted weather sealing and I got that too. I do have a question when I move from manual to EZ zoom sometimes it makes a funny musical sound it works great its just funny to hear this little musical sound. One last thing the reviews on this lens are all over the place but from what I can see it is a fairly nice step up from my 14-42R II not so much in the way of IQ but in range and build quality and usefulness. Thanks guys hope someone knows about the music thing. I do have 30 days to return. Jim A quick shot of my complex it seems to be fairly nice at 12mm. It was a dreary day and it was drizzling off and on but hey it rains everyday I get a new lens.
