I noticed this the other night, whenever there is a scene with a pure black screen, I can see two very faint white circular shaped spots almost right in the middle of the screen. I know that this is caused by some dust or a small hair getting behind the lens and distorting the light, but my question is, how do I get rid of that? I tried blowing into the very tiny opening under the zoom ring but it didn't work, when I look into the lens I can actually see a small hair that is most likely causing this problem, I just need to get it out of the way of the light path inside. How do I correct this? I'm extremely hesitant about using compressed air to blow in it because that's too much pressure, plus some liquid tends to squirt out of those cans. Thanks for the help.
