 How to clean CMOS? I am using 300D Post time: 4 月 20 日 |

I have some obvious black spots on the photos that I took. The black spots are obvious when I use large F-value (especially over F16) and slow shutter speed . (around 1/90 - 1/120) sec. How can I solve the problem? I suspect that there are dusts on my CMOS.......

same as mine.. but it has been said that this is a common issue. I have already tried to clean the sensor, but the problem still occured!!
but for me, just obvious in/> F18. In general purpose, F8 or F11 is really enough.
To clean the sensor:
1)make sure the battery power is good (the camera will check it for you, if not enough, it will not allow you to do so.)
2)turn off the camera, an take off the len.
3)Switch to M mode.
4)in the manu table, go to the last manu page, you may find one called "clean sensor"..or something like that,
5)select the clean option, select OK then press "SET", you may find the mirro is now open up.
6)using some air bump to clean, DON'T TOUCH THE SENSOR SURFACE BY YOURSELF, (EXCEPT YOU HAVE SOME SPECIAL TOOLS FOR THIS).
7)after cleaning, just turn OFF the POWR, the mirro will close.
Please make sure you have read the manu(book) careful
