(Yeah, I'm a point and shoot kind of guy) It cuts down the ultraviolet light entering the camera, to prevent it from affecting the picture. In practice, digital sensors are far less sensitive to UV light than film is, so, not much need. Infrared can be much more of an issue than ultraviolet with digital.

Every filter degrades your lens performance, mainly through additional reflections which reduce contrast and create bright spots in night photos. Therefore I recommend to use a filter only when you really need it. Lenses have a hard coating, so wiping of dust or fingerprints with suitable materials is no problem.

Lenses have a hard coating, so wiping of dust or fingerprints with suitable materials is no problem. for me, any interchangeable lens: if you scratch or chip the filter, it only costs how much? new filter, 72mm is about 90. any camera store will sell you the replacement (45 min). if you scratch or chip the lens, it only costs how much? factory service, starts at several hundred dollars. many days lost. (2-3 weeks?) only factory will touch damaged lens. Hans-Georg -- No mail, please. |

(2-3 weeks?) only factory will touch damaged lens. Crownfield, Beowulf, I've taken tens of thousands of photos over many years, but never scratched the lens. The main reason is that the lens is recessed inside a metal ring, so it's actually not simple to scratch it. For example, put the camera on a concrete floor with the lens down and the glass of the lens will not actually touch the floor. So I don't see why should I put a protective filter on the lens, particularly if it degrades picture quality. I don't know what you do to your cameras and lenses. Perhaps you really need a protective filter. In any case, the points have been made and everybody can make an informed decision. Taking night shots with lights with and without protective filter is an eye-opener. Do it. Hans-Georg -- No mail, please. |

I usually use multi-coated solid glass filters. Hans-Georg -- No mail, please. |
