樓主要不是電池有問題就是機子有問題 不要怪到D800去...
機子不就是D800嗎?? 我是覺得問題比較大的是電池本身!!

但是機身本身問題，那問題點就還是在"DSLR"這個型式身上...
現在可換鏡頭式相機並不是只有DSLR一種...
高畫素原本就需要更精確、嚴謹的操作相機才能達到更精美的結果
現代數位相機也不是只有D800才有這種情況...連X-Pro1 1600萬畫素都常常見到因輕微晃動而拍不出該有的銳利度。
要拍出銳利不晃動的照片恐怕並不是換顆有防手震的鏡頭就能張張完美
除了改變拍照心態，不要過度在意移焦、晃動等問題;或是多縮光圈求景深、多上腳架等方式。
若無法改變心態那倒不如換上畫素較一般的相機，才不會投資了高成本又得不到等比實質的提升，卻又帶給自已許多的困擾。

這個問題確實是有的, 不是空穴來風, 國外討論區也不少人在反應移焦的問題
Summary:
Nikon has acknowledged, found and understood the root cause of the issue. It has been eliminated in the current production (however, I guess we'll never know when and from which serial numbers on).
The root cause is a misalignment of the AF module when mounted, outside of Nikon's own production tolerances. But be asserted we are still talking micro meters here ...
The issue for affected D800 can be solved in selected Nikon service centers; such as Düsseldorf, Germany.
The procedure is currently rolled out to more Nikon service centers.
The fixing procedure for Nikon is a tedious one. It includes writing individual calibration values into the firmware. For larger deviations, the AF module will first mechanically be re-aligned. This may actually include the AF auxiliary mirror in some cases.
This method is believed to deliver an autofocus precision which is at least as good as of cameras from a fresh batch. I could not clarify if there is a chance for both methods being non-equivalent in some way. However, Nikon Germany does not think so. They rather wholeheartedly believe that the in-service calibration procedure resolves the issue as good as current production does, if not better.
Nikon does actually not know how many D800 of the early batches have been affected. Despite all oddities, the so-called service-rate of the D800 is unremarkable and only "sligthly increased" (compared to other camera models).
