Lensrentals是一間攝影器材出租的公司。
今天他們的部落格刊出了一篇關於D600時常入塵的文章，
事實上台灣也有許多D600使用者抱怨類似的問題，以下是原文的全文翻譯

We tend not to get too excited about sensor dust problems here; we clean sensors on every camera after every rental, so it’s just routine. When we started carrying the Nikon D600 they all arrived with a fair amount of
dust, but that’s pretty routine, too. Manufacturing and shipping can be a dusty experience.
我們不想對這個入塵問題太大驚小怪，每次相機還回來我們都會清理，這是例行作業。
當我們開始用這些D600時，他們本身就帶有相當程度的入塵，但這也很正常，
製造和運送過程可能是塵土飛揚的。

When our techs started complaining that D600s were all coming back from their first rental with a lot more
dust (despite being freshly cleaned before leaving) we didn’t pay much attention to that either. We all
remember the oil / dust issues the D3x and D3s had. Those mostly cleared up after a few cleanings.
當我們的技師開始抱怨那些第一次出租的D600總是帶著很多灰塵回來時(即使租出去前已經有清過)，
我們並沒有太放在心上。
畢竟我們都還記得D3X和D3s的油漬和入塵問題，它們大多清個幾次就沒問題了。

The dust kept reappearing with every rental, and more impressively – it was generally in the same location
(upper left 1/3 of the image). That did get our attention, so we started looking into the matter a bit. We kept
dust pictures for 20 consecutive D600s returning from rental and saw the problem was very real.
但每次出租，這些入塵就一直出現，而且更明顯  -大多是在相同的區域，畫面左上角三分之一處。
這就讓我們注意了，我們開始留心這個問題，
我們保留了20台租出去D600的入塵照片，發現這的確是個問題。

In general, about 1 out of 4 cameras requires sensor cleaning after a rental. All 20 of the D600s did.
大致上，每次出租後，大約每四台相機中，就有一台需要清理感光元件。
但這20台D600每台都需要清理。

Here are a couple of typical examples (f/16 blank wall photos, contrast and exposure increased). I would point out that these are downsized to 800-pixel wide images. What is barely visible dust on this is quite obvious on a full-size image. The large specs on this are quite huge at full size.
以下是幾張典型的例子(光圈16下對著白色牆壁所拍，對比與曝光增加)
我想指出這些是縮圖到800p的照片，縮圖中看不太到的塵點在原圖中是相當明顯的。

t’s probably pretty apparent that the dust is mostly on the left side of the image. I took all 20 images and
layered them onto one in Photoshop, using ‘darken if’ to show the pattern of dust from 20 cameras.
很明顯可以看出塵點大多出現在左上角。
我把所有20張照片用Photoshop疊起來，
並且用"darken if"來表現出20台相機的入塵模式。

photoshop中20台相機照片所疊的圖。

Again, with these downsized images, only the really large dust specs are showing up, but then, those are the ones most likely to show up in a photo. I would also add these almost all seem to be dust specs, not oil, since most of them can be blown off or stamped off using a Dust-Aid. They don’t require wet cleaning to remove as oil spots do.
再一次的，由這些縮圖，只有比較大的塵點才看得到，但也是在照片中比較可能出現的。
由於這些塵點都可以被吹掉，所以應該不是油漬。
它們並不需要油漬污點的濕式清理。

There are, however, a number of comments from experienced photographers that are having oil spots on
D600s. I’m not certain if they’re seeing the same, or a different phenomenon.
然而，許多資深攝影師提出他們的D600有油漬汙點，
不過我不確定看起來是不是一樣。

We aren’t absolutely certain about the cause, but when we have to look at the sensors for all this cleaning one thing is quite apparent. The D600′s shutter curtain opening seems a bit larger than the other Nikon cameras with a bit of a gap around the shutter curtain. It may well be the shutter movement is pulling dust onto the
sensor.
我們並不是非常確定什麼造成這些入塵，但經過這些清理過程，有件事情很明顯。
D600快門簾的開口似乎比其他的Nikon相機來得稍微大一些，快門簾周圍似乎有一點縫隙。
也許是快門作動時造成感光元件的入塵。

The real question is: Will the dust eventually stop accumulating on the sensor? I think probably so. There’s
some dust inside the camera that is getting blown out during early use through the shutter opening. But
that’s just an educated guess; only time will tell.
真正的問題是:入塵是不是最終會停止? 我想應該是的。
在剛開始使用相機時，一些原本就在相機內的塵點會被吹出來。
但這只是猜測，只有時間會告訴我們答案。

For now, though, if you rent a D600 we suggest looking fairly frequently for dust accumulation. We clean each one before it leaves, but given the amount of dust they return with it’s fairly obvious there could be dust dots on some of your shots if you stop down to f/8 or more.
現在，如果你租了台D600，我們會建議你經常檢查入塵。
每台出租前我們都會清理，但根據還回來的相機內的入塵量，
很可能有些你拍的照片(縮到光圈8以後)，上面會有塵點。

NOTE: I know someone will want to know. All of these cameras were from SN 300xxxx or 301xxxx.
We have another 40 D600s but since they, too, are from these SN runs I don’t plan any further comparisons. We’ll check again when we get higher SNs.
註:我知道有些人會想知道。這些入塵相機的序號是SN 300xxxx 或 301xxxx。
我們還有其他40台D600，因為他們也都是在這些序號範圍內，所以我不想再做進一步比對了。
等我們有更後面序號的相機時，我們會再確認一次。
