For quite sometime I noticed what looked like a piece of lint or dust on my pictures. I assumed it was on the lens, and clean it up, only to find it in the pictures again. I told my wife I think there is dust inside your lens, wondering how hard it was to clean the inside of a lens,. I did a google search and watched a few youtube video’s. I don’t mind tinkering, but I haven’t always been successful. Below is the suspect.
I went to Canon and found an article on dust inside my lens. Someone in the comments told that person to try another lens, if it is still there, you have dust on your sensor. I looked at my pictures from my 18-55 and 75-300, sure enough I had dust on my sensor.
For each camera it is a different procedure. My wife’s XSI has a self cleaning mode. My T5 you set it to clean manually, remove lens, the shutter is opened. Use a rubber air blower to remove the dust. Much better than taking apart a lens that didn’t have a problem in the first place. I’m sure most people know this, but I didn’t.
