更难的拍摄条件：D90视频实拍演示

    下面这段在明亮的白天拍摄，但是拍摄者或者相机处于不断移动颠簸中，并且拍摄以一定速度运动的物体

    上一段视频拍摄时间较长，几乎接近了D90允许最大的5分钟，此时我们的D90手柄处能明显感觉到D90的机身温度再升高。不过有媒体朋友称他们收到的D90并无类似问题，那么但愿这只是个体现象。D90装上AFS镜头后，最大的好处是方便视频拍摄时对焦，但是一边拍摄寻找不标，一边变焦，再进行对焦，对于一般的用户来说确实够忙乱的了。我们建议大家看完上段视频，你就能自己领悟出使用D90在移动中拍摄视频的优点与不足了。

较明亮的室内灯光环境下，但光源类型较复杂，手持不断移动中拍摄：

    视频拍摄的实验再次回到夜景灯光环境下，此次的光源条件更复杂，拍摄时间更长，并且我们在中途更改了曝光补偿，不断的对焦，再变焦再对焦，也算是体验了一把手忙脚乱中拍摄的感觉：

D90第二期评测小结：

     本期我们并未掺杂进太多内容，只是仔细探讨了一下D90的视频实际拍摄效果。笔者以为，D90作为第一种支持动态视频拍摄的数码单反，是具有特殊的历史意义的，就眼前来说，为用户使用单反相机带来更多理由，使他们获得更多的使用乐趣。从长远讲，为数码单反的未来画出了一条发展路线——尽管这可能并非是条好路。而且，回溯数码单反30多年的发展史：昔日以Marvica为代表作为“静态摄像机”被分离出数字摄像机阵营的数码单发的前辈们，今天以D90的形式完成了一种轮回……

D90视频拍摄的优点：

• 成像潜力不错，环境理想的情况下能够拍摄出素质不错的画面
• 虽然损失了自动对焦和VR防抖，但曝光补偿和手动对焦依然能够帮助拍摄
• LV模式转换到视频拍摄模式十分方便，适合入门用户
• 拍摄贞数尚可

D90视频拍摄功能的不足：

• 拍摄时只能MF，现代单反镜头同时进行手动对焦和变焦操作较困难
• 机身的测曝光系统似乎不适应DV拍摄的需要，对环境变化适应较慢，几乎相当于DV的手动曝光模式，在夜景或正午拍摄时，需要不断改变曝光补偿
• VR防抖在此时形同虚设
• 耗电量较大，机身MiC会收集机身上任何操作的响声，因此对相机拍摄进行曝光补偿等操作可能会影响录音
