I was wiping my scope down the other day and my wife asked why I don’t use a UV or Polarized lens cover on my scope. Being a hard core photographer, she knows her glass. She happened to have a spare UV filter that I screwed right on to my Aztec Emerald. When I went out shooting with Oregun this past weekend, I swear that UV filter made things seem brighter. Anyone have experience using UV or Polarized Lens covers on their scopes? If for nothing else, I love that it keeps the dust and dirt away from my scope glass.

Obviously, filters do not give you more light, they may reduce the amount of light. For polarizing filters I seem to recall the general rule of thumb is that you lose 2 stops of light. They cut the glare from reflections, if you are near water in particular, that could be very helpful. UV filters have little effect, it may reduce haze on sensors, but I haven't heard if they have the same effect on your eyes. Some filters are difficult to clean, and I always seem to trap dust between filter and lens. Now there is more to clean. The sales pitch goes like this: would you rather scratch a $50 filter or a $500 lens? In practice, the coatings are very good, and you don't really scratch either if you are reasonable careful (blow off dust, use microfiber or lens tissue, use an appropriate solvent etc). Personally, I prefer hoods to filters as I don't want to risk compromising the quality of my photos.

Thanks for the feedback Allan. What I meant to say was that things appeared "clearer" not brighter. I typically use the sun shade on my scope but having the UV filter on there seemed to improve the clarity. Then again, it could have been my imagination or my old eyes playing games with me! Ahhh, the power of suggestion...

When dealing with harsh sunlight and glare using a
yellow or CPL on your scope works very good .
