我拍了一段优酷视频http://v.youku.com/v_show/id_XODI0MDcxMDg4.html
大概在第5-6秒，传感器动的时候出现杂音，我在※※※※※※※上找了一些E-PL5的开箱视频，没有听到明显的类似声音，但是※※※※※※※上那些视频杂音比较大，我也搞不清是否有这种声音。
我印象中以前肯定是没有这个奇怪的开机音的，拆开镜头开，在发出声音的同时传感器在动，我问了问奥林巴斯客服说那是防抖启动，相机目前工作正常，只是每次开机听到那涩涩的声音总是担心坏了，求哪位见多识广的大神帮我看看吧，去了趟保修点，一老太太说保险只负责机器是否工作正常，我这种的不算问题，哎。。。。

我在国外的网站上也问了这个问题，别人回答是貌似没有这个声音，中间的传感器也不会这么明显的动
全文是这样的
On powerup, your sensor is being driven to the bottom of the camera, and we hear the motors moving it down as far as they can. Then it returns to the center. This takes about a second. The whir sound is from the motors.

My EPL5 does not do that. When it's powered up, the sensor hardly moves at all. I hear two quick soft clicks when it powers up, and the sound is much less than a second.

My guess is that your EPL5 is not parking the sensor correctly when it's powered down. Mine will sound like yours when power goes off. The sensor gets moved to what I assume is a rest position for travelling. So maybe your camera has to move it when powering up.

What do you hear and see when powering down? Any error messages about the IS?

最后那个声音我刚买来是没有的，最近磕了一下产生的，哎，保修点不愿管我这种海淘拿国际保修卡的，楞是说没毛病，个体差异。

我的也有，不过好像没你这个声音那么刺
