Originally posted by bertwert I meant do you use a UV filter for protection or a Protective filter for protection.
For FSLRs I use a UV filter and for DSLRs I use the new hardened glass protective filters (in addition to a lens hood).
When I want and need the best IQ, I remove the filter and am extra cautious. If I'm shooting a non-WR lens, I will also use a filter as an extra barrier from the elements.
When I was a pro and insured for accidents, I usually did not use a filter....and yes, I had more accidents than I'd like to admit. Now that I'm no longer a full time pro, I almost always keep a filter on as I cannot justify the cost of
either insurance, the deductible, or replacing my lenses.
Not to digress from your post, but I wonder if anyone has found favor in brass, aluminum, or plastic constructed filters? I'm thinking in terms of easier removal upon damaging impacts.
