部 30d 剛剛買了兩個月 ，用細光圈影，發現CCD 有塵 (因為Try 過兩支鏡，都發現同一位置有塵)
想問CCD 入塵 是否正常，但我部 30d 卻太約有六、七點之多。
各位C hing 會自己洗或上C.S.，請比意見我

I had that problem as well before. What I did is just lock the mirror up, then pump it a few times, then problem fixed. You may want to give it a try first before you send it to CS. Good luck.

其實而家有樣野叫 Sensor Clear既筆... 百零蚊, 放便又有效.. 如果D塵Pump唔去可以用佢...
