I'm really liking my new G5 camera, but I'm finding the zoom ring on the included 14-42mm lens (H-FS014042) to be pretty frustrating. I has a surprising and variable amount of friction in it, so getting smooth zooms is pretty much impossible, which I suppose is okay for still photos, but if you want to change the focal length during a video, the result will be necessarily jerky. I also have Panasonic's 45-150mm lens (H-FS45150, and my previous primary camera is a DMC-FZ50 (internal zoom, so I admit that's kind of apples-to-oranges), so I know very well that Panasonic's zoom rings don't need to perform so poorly. Is this behavior typical of the 14-42mm lens? Did they cheap out the production quality of the default lens with the rationale that many users would be buying other lenses anyhow? Or did I get one with a mild manufacturer's defect that might be eligible for replacement under warranty? Alternately, is this a problem that goes away on its own with use (i.e. something that needs to loosen up over time)?
