We need to figure out if the dust is on the lens or on the sensor.Do you have an additional lens? If so, do you get the same specs on your photos when you use that lens?Let me know.
Can you take the lens off the camera and look carefully to see if the specs of dirt are on, or in the lens elements?
You can use a soft cloth or camera brush on the lens and on the mirror. You can also use canned air and blow it out. CLICK HERE for a video. He is cleaning a Nikon but the methodology would be identical.If the dust is inside the lens, then the lens will have to be professionally dismantled and cleaned.Please let me know if you have any further questions and good luck.Steve
