What is wrong with my lens or camera?

I guess that explained why the blower was unable to blow away the dust.

I held my lens up to a light and looked through it, I saw some fungus like stuff... all over the area... []


I guess I have no choice but to send the lens back to Canon to get it clean asap and hope the fungus still not too serious until it has destroyed the coating of my lens.


Will camera body develop fungus? I normally hear people mention fungus in lens, will fungus grow inside camera body? In my case, will the fungus spread from my lens to my camera body? Also curious will fungus spread from one lens to another?

I concur that it is a dirty sensor. I had the same problems before myself. It doesn't matter that you've never taken the lens off b/c dust can get into all sorts of places regardless. I believe I ended up using a lenspen sensor cleaner and giottos rocket blower to get my sensor clean. good luck!

you have a very dirty sensor, and this is normal. Let me guess, the first image was shot at around f/16 to f/22 and the 2nd image was shot at around f/11 to f/16?. Try to shoot at largeraperture and you'll see a noticeble difference. As far as cleaning your sensor, sometimes blowing it with a blower will not eliminate the stubborn spots,hence you need to try other approaches like sending the camera to Canon for a cleaning or do-it-yourself cleaning. Just google sensor cleaning and you should find many tips. Also keep in mind that even though you never remove your lens from the camera, dust can be created by moving parts like mirrors and shutter. Another way is to use the dust deleting program that comes with your DPP software. Good luck and don't scrub![]

The reason why fungus grows on a lens is because it can utilize the lens coating for food. This may or may not be possible with fungus inside the body but I would be more concerned with corrosion inside the body with all that condensation. Especially with circuit boards and current from the battery.


It might be a good idea to contact Canon and see what they would recommend and how much it would cost.
