I was able to fix a GX680 that I bought for a song because it was broken. I have two lenses for it, the 135 5.6 and th 150 4.5. Other than the slight difference in field of view, is there anything about thee 135 that makes it preferable to the 150? FOV wise, I don't need any different from the 150, and while it matters less on this camera than on others I was thinking I would just keep the 150 since it is the faster lens. Before I sell the 135, I was wondering if it was known to have something better about it.
