Greetings all! I am a very new photographer and think I may have gotten something on my sensor. I called a local place that cleans them but they gave me contradicting information: First he said that the spots in my photos should not change size regardless of the zoom on the lens, then he said that it could change when I was just going to try and clean the lens again. I am just trying to find out if the spots could be on the sensor and not the lens, even though they change size when zoomed in or out. Want to get that cleared up before spending $50 on something that may not resolve the issue, I already have checked the lens and see nothing wrong on either side. These are two photos where you can see the difference of the spot in the top right corner thanks!
