In a perfect world yes. I'm not going to sell any of you the idea of a UV filter. Murphy's law will do that for you. I've never touched the front element of my 80-200 f/2.8 and always use it with a hood. But that didn't stop a volleyball from splashing water all over the front of it, and it would stop the neighbours lawnmower from flinging a rock at it, or some kid in a park tripping over and smacking it with something sharp they were holding it at the time. By all means it's a risk you take. A risk I don't, for a measly $100. And you're kidding yourself if a B+W filter is going to cost you quality in your photos.
