x14-42长焦胡片早有所闻，以为更新固件已经解决。昨天进了一个，发现和老14-42比画质退化不少，又是纳米镀膜又是ED镜片的应该进步才对呀。今天对比做了很多测试发现，只要高于1/400秒该头的素质就显现出来了。低于这个值镜头长焦很模糊。应该是快门开启的震动干扰了对焦或防震模组的稳定性造成胡片，不知以后会不会出固件弥补。

顶出来

自己顶！

拍的时候还不知道什么原因，如今知道了，郁闷

可是也有不少人说根本没遇到所谓的“糊片门”闹得我不知该不该进一个

支持樓主，一起出力，解決問題！

顶，G5的电子快门应该没问题。

看看 p的12-35长焦端的表现，是对焦前移，并且是稳定前移。

大家到松下网站投诉吧。

G5有电子快门

顶一记，这个头我很喜欢，小巧对焦速度快，希望能解决这个问题

是不是说关掉防抖就好了呢?
顺便问如何关防抖.

多点人投诉松下就会重视，改善固件。

已投诉，给我发了个短信，告诉我收到投诉了。。。

看此图，似乎说明x1442在14-20以及21-42两个焦段使用了不同的镜片组或者神马东西，反正是有区别，而普通的1442全焦段的最近对焦距离是相同的。

这个和我们日常使用的感觉是一致的，x1442广角端画质和长焦端确实差距较大，现在看来就是14-20了。。。

其实松下可以更新机身固件及镜头固件来解决问题，机械快门先开启，等震动结束后再开启电子快门曝光即可解决这个问题。

松下忙着资助登※※※呢，没空管这个现在。。。

希望松下能够重视。

和我测试的结果如出一辙！松下设计上有缺陷。

请看这里：
Unfortunately, we ran into trouble with the Lumix G X Vario lens at our near full telephoto, finding the same characteristic image doubling that we found with the Olympus E-P1 (for exhaustive detail on that camera's problem, see Blur Anomaly write-up here). Because both companies use different image stabilization strategies, we suspect the cause is slightly different, but the doubling appears whether the X lens's stabilization is on or off.

The above image blur occurs on both the GX1 and E-P1 cameras with the Lumix G X Vario PZ 14-42mm lens, though the angle of blur is more vertical on the E-P1 than the diagonal motion we see here in images from the GX1 images. The blur is most noticeable at shutter speeds where it should not occur, 1/160 and 1/200 second, at or near full telephoto. We think the opening motion of the first curtain is vibrating an element inside the lens with a motion that the image stabilization system can't fix, since it occurs whether IS is on or off. (Initially, we thought it was worse with IS on, but additional testing revealed that turned out not to be the case.) At 1/320 second, the second curtain has started its closing motion before the first curtain hits the bottom of its stroke, so no vibration occurs during the exposure. Our best suggestion is to either avoid the lens or avoid these shutter speeds with this lens at our near 42mm, because the blur occurs in almost every shot.

那长焦端就彻底沦为阳光头了

有可能是驱动线圈自身的驱动力不够或镜片主太轻。
