So I was out shooting this evening like always and noticed some small specks in my view finder. I assumed this was from the glass face of the lens getting some dust on it. Long story short I found out there is a small black speck actually inside the lens?? I always keep the lens covers on and when Im not shooting the lens and body are both in their carrying case. When I shoot I dont actually see the speck in pictures though. Anyone have any advice on what to do with this? Thanks for your time.
