《除塵不如防塵》

最近在公共圖書館借了一本書，叫《EF LENS WORK III - The Eyes of EOS》。

書中有部份內容寫得很好，所以抄出來給大家看看﹝不是每個人都像我如此空閒啦﹞：

Preventing dirt and dust from getting in the camera body or onto the lens when changing lenses

Changing lenses in windy places can cause dirt and dust to enter the camera through the lens mount. Any dust that gets on the image sensor may appear as black specks or smudges on the image. To avoid this, we recommend doing the following:

• Change lens quickly in places where there is no wind
• Always attach the body cap to the camera body when no lens is attached
• Change lens with the camera mount facing down
• Do not place the camera face down
• Watch out for dust getting inside the body cap on the camera or the lens's dust cap

Image sensors are very delicate. If dirt or dust ever needs to be cleaned off the sensor surface, either do it as described in the camera manual or take the camera to a Canon service center.
