How do you know you have a dirty sensor?
If you shoot Av (aperture priority or preferred) and have fast lenses and shoot with them wide open, you won’t notice a dirty sensor much if at all. However, as you stop down (reduce the size of the aperture) you will start to see the dust, if you have it.Put any lens on your camera, set the camera to Av mode (aperture preferred) and stop down to f/16 or smaller.
Take a picture of a white wall or a white computer screen.
Look at the picture on your computer. If you see spots, you’ve got dust. Note, it’s useful to try to remember where the spots are so that as you clean you can see if you’re making any progress when you check again.
