Does Sigma Use Cheap Coatings?
I've had my Sigma 17-50 for a little over a month. Today, I was going to take some pictures and just as I was going to remove the lens cap, I fumbled the cap a bit and it touched the lens. When I looked at the lens closely, it looks like either the lens was scratched by the cap, or a piece of the coating came off. Originally, I thought that maybe it was just some dust. It doesn't feel like a scratch (feels smooth) so I do believe it is the coating. I haven't tried cleaning it (don't want to make it worse). Either way, I took pictures and there is no effect on the pictures (I also have no plans to sell the lens any time soon. It's my favorite lens right now).
Has this happened to anyone else? It seems crazy that this would happen. I have seen the abuse that lenses can take and not break or scratch so this is also leads me to believe that it's just some of the coating. Hoping for some recommendations on what to do. Thanks.
