State University, Raleigh Lines: 22 This is a rebuttal to decwrl!(what is hip?)'s comments on filters. First, there is no need to apologize for being a Leica fanatic -- that's a well-respected sub-hobby in photography. One should be aware, though, that not everyone can justify the expense of Leitz products, and that information published by Leitz cannot be expected to apply to popularly-priced Japanese products; the fact that all R-series Leica lenses contain UV absorbing glass does not tell me anything about my Vivitar zoom. The extreme lighting conditions mentioned are also infrequently encountered by the average camera user. Optical degradation from a *good quality* filter will probably be undetectable in most cases. There is no point trying to enumerate the minor hazards that endanger the front element of a lens. I prefer to transfer those hazards to a filter that is easier to clean and easier to replace than the lens is. I look at it as insurance payed with one easy premium. -- _Doctor_ Jon Mauney, mcnc!ncsu!mauney \__Mu__/ North Carolina State University
