I think that using a UV filter is simply a peace of mind issue. If you feel better and more secure with a filter protecting your lens, then go for it. I personally have not used one for over 10 years. And, I have only one scratch on one of my lenses. And, I have no idea how that happened...but, I can not see any evidence of its effect in the images. I always use a lens hood, and if I am in a situation where I am still worried about protecting the lens, I put the lens cap back on, and the next step is putting the camera back in the bag.
