….that is the question.
For years you have probably heard from your local camera dealer. “be sure to us a filter to protect your lens” referring to a UV filter that usually screws on to the front of the lens.
I say don’t.
In a general rule of photography I do not put anything in front of the lens that I would not want in the photo. You wouldn’t want someone standing in front of the bride when you take her portrait would you? Of course not, it ruins the image. So why would you place something in front of the lens (a filter) that could possibly ruin your shot? The more gizmos you have the more that can go wrong.
