Forgive me, but... concerning the previous thread about filters
I (beginner) am confused about filters in general. Does the Moose filter also offer protection for the lense, or should you also have a normal filter for protection to protect your filters? What filter configuration do you recommend for a lense as far protection and polarization and UV. Are they all stacked on top of each other. Does the Moose filter do all of these. I have a Sigma 28-80 lense that came with a "Normal Filter". What does this do. Protect the lense? Thanks for the help. I am a beginner and am trying to understand some of these issues.

Most people use UV or skylight filters to protect the front element. UV's absorb UV rays and skylights reduce haze, by absorbing blue, especially at higher elevations.
The Moose filter is a combination circular polarizer and 81A warming filter. This is especially helpful with wide angle lenses, say 20 or 24, where the extreme angle of view would lead to vignetting (darkening of the corners) when you stack filters.
I'm not sure, but I believe that this is a multicoated filter (the multicoating improves light transmission and reduces flare).
I'm not sure what the "normal filter" is. I'd assume its either a UV or skylight filter. What does it say on the filter ring?
Hope this was helpful.

Any filter protects the lens. You don't need to stack a UV filter on top of another filter for protection. In fact, stacking filters puts more layers of glass between the subject and the film, which tends to degrade the image somewhat.
