Just taken photo with my new 350D with 3000 shots!!
I start to notice there is some dots appears on my photos, same spots, at least 5-7nos. Make me very very uncomfortable! Check the lens, no duct, all clean!!
I guess it is dirt on CMOS sensor.
I wonder when those duct enter to the CMOS, mostly when we are changing the lens? I am right? or there is no way, the duct enter CMOS...Can it be minimise? So the chance of cleaning the censor will be alternate few weeks/months!!
Goodness, if send to Canon cost $21, mean a year may cost me $100++
If not, self cleaning, pay myself $21, but if I spoilt the CMOS sensor, I need to blame myself~~.....oh no!!
So how often you clean up the sensor?
