Hoping someone can give me a bit of advice,
I've got a tiny mark on the lens/or dust spot deep inside the lens that shows up when on Max Zoom and against the sky ..
I can see it through the Viewfinder and after checking on another lens (same type) concluded it's on my Lens ..
Is there anything I can do about it or am I stuck with it ?
