Olympus OM-D 12-50 or 14-42

if you are more into street photo, i would like to urge you to get the 12-50 mm, its quite stealthy especially when you zoom in the subject, as compared to 14-42mm which has a noticeable zooming mechanism. but all in all, as what other have said regarding 12-50mm advantages..they are all right..:-) get the 12-50mm!! hehe
