Try to take a complete white photo, use a white paper and see whether there is still black spot on the photo.

If it is the case, may be dust on the sensor you may need to Canon CS for cleaning.

只係sensor上面有塵，用波波吹下佢睇下點

[Obi-Wan]

very easy to fix!
clean sensor by pump

[Douglaschow]

小事!唔大濟! sensor入咗塵?

[hellow4u]

張相咁暗又咁濛既？

[pongyee]

入咁多塵真係少見，部機重係新o既添。

換鏡時要注意下環境，可以o既話，個機身mount 唔好向天。

40D 有自動除塵，正常用唔會錦掛？　　

上面個ｄ可能唔係塵，你有冇吹左ｄ水點入去？　　

[hellokitty_vip]

1. 一定唔係水. 一係毛. 一係塵. 未fully confirm
2. 自動除塵唔會除到 夋鏡, 反光鏡d塵 wo... 再開過機幾次la,都係咁
3. 未知dirt正確位置

吹sensor ? 係咪要先除下第一面反光鏡先? (機內)

像鏡頭發莓

[Obi-Wan]

cy001 (發莓), chansimon (上面個ｄ可能唔係塵), don't play la!!!!

the problem is caused by sensor dust particles, the CANON dust free system is much much weaker than that of OM, so it is very easy to get dust inside.

D U S T can be easily removed from the low pass filter glass by a powerful pump

這現象在我的D80試過, 是CCD髒了、后來我自已用火酒加棉花棒將它抹掉 ....
