I've seen a few people with the Panasonic 14/2.5 and the DMW-GWC1 wide-angle converter. I'm wondering if anybody has had a chance to compare it to either the Olympus 12/2 or the Panasonic 12-35/2.8 at the wide end. Yes, I know it's just a conversion lens, but neither of the other 2 options are exceptional at that focal length for landscapes (smeary corners), so if the 14/2.5 + GWC1 combo is reasonably close, I'd be interested in giving it a try. I'd also be curious to know how much the AoV shrinks once you correct for the additional barrel distortion from the GWC1. Now that my goto 12mm lens (ZD 12-60) has failed again, I'm trying to gauge the alternatives. Thanks!
