I noticed that there's a little dust on some of the interior elements in my camera lens. Should I worry? I know that there's a risk of fungus but I keep the lens in a moisture controlled environment..

If you were out on a sunny day and irised down to 11 or 16 would it photograph? Thats what I would be worried about.

Any dust at all will decrease light transmission and change the speed of the lens. It might also impart a desaturation effect/color shift. But maybe I assume there is more dust in there than really is?

It's not too bad.. but when I shine a flashlight at a particular angle I can definitely see it. The lens has some huge lens elements, so it should have negligible effect on the exposure, but some dust has gotten up in there.
