Filter type for Nikon zoom lens I recently bought Nikon's D100 and a Nikkor 24-85mm f 2.8-4.0 zoom lens. I have been told that I need a UV filter for the lens. What brand/type do I get? Thanks!

Dear Alison: You're pretty safe if you buy a major brand name UV filter from Tiffen, Hoya, B+W or Heliopan. If you buy from a store, before you leave you may want to install the filter, set the zoom to 24mm, and check the corners of the image. Sometimes a filter's threaded band is thick enough that it will cause vignetting at the wide angle setting. This is unlikely, but should it prove to be the case, you may have to find a low-profile UV filter. I suspect Nikon's own UV filter for the lens may be low-profile, and require high monetary sacrifice. For fun, you may want to ask your advisors WHY they think you need a UV filter. Generally speaking, it is a good idea, but you may have fun collecting different "Explanations" for using one. Common answers: 1) To protect the front lens element from getting scatches or other damage (A pretty good answer). Keeping a good lens shade in place on the lens can help, too. Sometimes the shade and filter absorb impact damage that would otherwise have affected the lens, with the result that your D100 body becomes an overpriced paperweight while you await the repair of the lens. 2) To absorb UV radiation that may otherwise be transmitted through the lens to the film, where it lends a slight (and considered undesirable) bluish cast to color photos and slides (Also a pretty good answer). There are some differences among UV filters. Some absorb more UV than others, some have no front threads so that you cannot stack additional filters on top of them, some may have additional properties to prevent them from being inexpensive (joke). (Optical purists sometimes engage in lively sideline debates about whether a relatively inexpensive piece of glass (the filter) can improve the image quality of a relatively expensive optical system (the lens). See what you think...)

Maynard, great thoughts and ideas. I will do some more research based on what you have told me. Thanks again for the in-depth response.
