呢D黑點咩黎架???唔係CMOS卦?因為clean過, only收细細光圈先見到,而且位置不變. 1000 X Thanks for answering.

Take it to the your CS to fix it or use a blow dryer (w/o brush) to DIY.

Position unchanged should be dust!!

Otherwise, it will be dead pixel and how old is your camera?

是censor or 鏡,thanks

是什麼相機呀？如 DSLR 可自救，打開快門，將相機mount向下，以blower 吹幾次，看看效果如何！如不得其法，拿往 canon 處清潔吧！

哦！是350D，光圈收細致40。其實不用擔心，如果一般2.8-22光圈沒有問題，可以不理！

Thanks madxngai:
This is the problem of the camera body or the lens?

[madxngai]

你有沒有其他 lens 呀，如有換來試試！我估多是body問題！

They are dust on the sensor surface.

Read the manual for self cleaning.

To minimize dust problem, turn off the camera before changing lens, do it indoor if possible in a non-windy place.

Shooting with wide aperture minimize the problem too.

There is also other ways to clean it yourself, when your confidence builds up.

Sending to Canon is an option, but cost $300. Think twice before sending in, sharing in internet or print to 4R may not need to worry about dust issue.
