Is the lens okay?
I was very lucky. No damage.
I have a UV filter on all my lenses. The reason is that, when ever I inspect the lens after a weeks use, I find fingerprints on the lens, and dust sticking to the fingerprints. I prefer to clean the filter with soap and water, and would not even think of doing it with the lens front element.
I have yet to encounter ghosting and artifact with the filter on.
