**** **** From the keys of Steve Henning, AT&T Bell Labs, Reading, PA mhuxl!smh > The notion of always protecting a lens with a low-effect filter, such as a > UV filter, is considered very controversial among professional > photographers. The reason is that any extra glass-to air interface, even > with modern coatings, reduces image contrast measurably. One often over-looked accessory that is very important is the lens shade. It not only improves image contrast measurably, but it protects the lens from most incidental contact. I use original equipment metal lens shades on all my lenses. I must admit that the shade on my 24mm lens is almost a joke, but the others are very important.
