How often should I clean the inside my camera i.e. the sensor and viewfinder? Get it professionally done?

I may be kind of paranoid, but I

I clean mine with the Visible Dust Arctic Butterfly brush, but only when I feel that I absolutely have to. Still, that has been more frequently than the two of you report ---- I

How Often do you clean the sensor?


The answer: When its dirty.


I have cleaned my sensor's several times. It is not rocket science but takes a little care.


Take a picture of a blue sky. Put it on the screen and go over it at 100% view. If you do not see any splotches then do not clean it.


You can send it in to Canon for a thourough cleaning.

Same is true for my 7D. My 5DII is a different story - larger sensor, also perhaps a less efficient cleaning mechanism? Regardless, I also use aVisible Dust Arctic Butterfly 724 Super Bright and it has worked well for me (sometimes taing a few attempts).

Shooting with the lens cap on will reveal hot pixels. Shooting a high key white background will reveal dead pixels, and can reveal dust. The trick, whether shooting a clean white background or a clear blue sky (either will work) is to stop your lens down to the minimum aperture (e.g. f/22).

I have some dust that appears if I shoot at white background with minimum aperture. I tried to blow it out, but that didn't work. H have bought the cleaning devices recommended on this site, but am a bit scared to try, even if I have access to sterile dust-free lamin air flow hoods at the university. Someone back me up, please!

Lars, just do it^®. I have done it in my home with no issues (even though I also have easy access to laminar flow hoods at work).

My 5D is the Chuck Norris within camera's. No fear for dust here, the mirror knows the roundhouse-flip.
