This may be your opinion, but it is not correct. The X lenses have a well-documented problem with the shutters on the G, GF, and GX cameras in the 1/80-1/200 shutter speed range. I shoot with both the 45-200 and 45-175 and have no problems in these shutter speed ranges with the 45-200 at 200mm but about 1/3 of the shots show an edge-doubling blur at 175mm on the 45-175 that they do not show at slower or higher shutter speeds. It's not technique when it's this specific a range of shutter speeds. Even dpreview saw it on the 14-42 in their review of the lens. Is your technique "better" than their testers? Doubtful. You have a GH2, where the problem seldom surfaces because the shutter has a different vibration signature than the other Panasonic cameras.

There have been many complaints about these lenses but IMO people forget that they are shooting handheld with a 300-400mm (35mm eqv) lenses and their technique is simply not good enough.

Will the vibration issue from the shutter be an issue if OIS is off and the camera is mounted on to a tripod? I'm worried that this may cause my long exposures to come out blurry.

If you have a camera/lens combination where the edge doubling blur is an issue, the issue is between about 1/80-1/250 shutter speeds. Slower or faster speeds are not a problem. It happens whether you have OIS turned on or not. I have not tested the lens on a tripod, but others have, and it happens with the lens on a tripod, too, as having the camera on a tripod does nothing to damp the shutter. If you use faster or slower shutter speeds, there is no visible problem. Longer exposures on a tripod should be fine because the "vibrated" part of the exposure is a small part of the total exposure.

How do I know if my camera/lens combination have the edge doubling blur issue or not? It's the first time I've heard of it and I don't think I have read any reviews that mentioned this issue affecting the Panasonic X 45-175mm lens. I'm somewhat scared of buying that lens if this issue can affect my photography.
