I had a 77mm polarizer filter that got rain drops on it and it was ruined. Does rain water dissolve the coating on the filter?

Never heard of fresh or rain water damaging a polarized filter lens. Salt water might. Sorry, wish I could tell you what happened. I know it has a plastic coating on it.

I've had that happen a few times, it hasn't done a thing to mine... they seem to remain unaffected with the Nikon brand..

No, rainwater should not eat the coating. You do want to dry it and keep it out of the rain if possible. The one issue you can get is if water gets into the ring it can get between the glass sandwich and ruin the filter. In 30 years, I've never had that happen with a Nikon CPL, but I have heard of it from others.

You need a UV filter. Trust me, better for a $10 UV filter to get scrtched then your lens. And a circular polarizer is a must have especially since your shooting water shots.

No. When you first run water through the filter you may get some cloudy residue, but after that the water should be clear. One thing you may want to check is the water source that is going through the filter. Fill a glass with the water you have been using and see if it has the debris. Another thing you may want to do is use bottled or filtered water.

A high quality filter should not degrade the image quality in any noticeable way. There are multi-coated filters available optimized for lens protection, and if these are not easy to find then a UV filter will work fine. I agree with the previous answer that protecting the front element of the lens is a very most important thing, unless all your work is in a clean dry studio with the camera on a tripod.

The water in the filter is also concentrated with vitamin c... you will eventually see it completely dissolve as the new water continues to interact/mix with the water.... remember the water doesn't travel through the filter for it to be effective. It just needs to contact the vitamin c...which it does through mixing inside the filter. Hope this is helpful.

Yes, but we had to wipe off the haze with isopropyl alcohol (use sparingly) and a soft cloth. If water droplets stay on top and don't soak in, you are sealed. Some polished granite doesn't need to be sealed. Check the water droplet test in a few places.

Same thing happened to me with the filter collapsing--I plan to check status of filter every so often and apply glue if needed. I believe the glue dries out prematurely.

The short answer is you need both. Circular Polarizers allow you to control glare and light diffusion - in other words, when you turn the filter, you can darken the image or lighten the image, as well as reducing glare from reflections or increase the "blue" in the sky as well, among other things. If you're going to take outside pictures in daylight - especially around reflective surfaces such as glass, metal or water - then having one of this is critical. However, Circular Polarizers (when rotated properly) will slow your lens down by 1-2 stops, so you only want to use them in brightly lit situations where glare, etc., is present. UV filters originally reduced ultraviolet coming into the lens in order to cut down or eliminate a "blue cast" on film, as well as to protect the very expensive "glass" at the front of your lens from getting scratches from constant cleaning. UV has long stopped being a problem, so now these filters are used primarily to protect the glass at the front of your expensive lens. They keep dirt, dust, finger oil and debris from touching your actual lens, so you never have to clean the lens itself... which means your lens will never develop scratches. UV filters are cheap to replace (by comparison to lenses and Circular Polarizers). They don't affect the speed of your lens, nor do they affect the color your lens "sees". I would suggest, though, that you get a good multicoated UV filter so ghosting and other reflective problems don't occur. All Circular Polarizers are already multicoated, so that's not a problem with them.

As far as I can tell it's glass. 2 layers that like your polarizer turns and gets darker as the 2 layer interact. Haven't really tried it yet so I can't comment on how well it works. But it goes from a light gray to so dark you can't see though it.

I'm not sure of what your question is about ,the housing is weather proof rain drops could spot the outside of the plastic lens. May have a problem if you live where the temps get very cold with pan and focus.

Hey Kathy, we use Ultra ever dry to coat components from water/moisture ingress - not sure about filter oil. There are two coatings, one bottom coating - grey and top coating is clear. cheers,

Google search turns up a variety of suggestions depending on the brand of polarizing filter. Lots of entries, I read a dozen, none of those replies or comments were using LensPens. One said microfiber cloth, some said "special cleaning fluids" but not consistently 1 brand. Also suggested, "pec pads" and "cotton balls". The simple answer is the polarized coating on the lens is not LensPen suitable. Google, call or chat online to camera lens supplier depending on your brand of filter.

As everyone else said the ring gets screwed to camera lens. Use UV filter to protect camera lens. Polarizer filter makes sky bluer and cuts glare on water. Florescent filter makes that type of light more natural. The macro filters can be used 1 at a time or 2 or more. Practice with them until you get the look you want. I haven't used the hood yet. Just try all the pieces and see the outcome. Have fun!

Depending on the lens, it's not usually a good idea to use both filters. UV haze filters are pretty useless and are usually mostly to protect the lens, which the polarizer will do. Unless you spend a lot on a UV filter, it's actually going to degrade the quality of the image. If you stack too many filters together you start to get a vignette effect because it lengthens the barrel of the lens, and the inferior glass will degrade the quality of the image further. Use the circular polarizer to reduce glare and reflections or to stop down a fast lens to use in bright light, otherwise use the UV filter or no filter.

Yes, I had this happen and called Alcon about it. It turns out that you cannot go between Clean Care and a multi-purpose solution. The chemical composition of multi-purpose solutions is incompatible with the neutralizing gear in the Clean Care case. If you use multi-purpose solution to rewet your lenses (which is what I did), they absorb some and react negatively with Clear Care. The Alcon representative said that once that happens, the Clean Care neutralizing disk is ruined. I don't know why this information is not printed on the box (or posted at the web site). If you call Alcon, they will send you a replacement case that you can use with a fresh pair of lenses. Yes, I had this happen and called Alcon about it.

Let me quote Tiffen (go to their website's FAQ section): "The Tiffen Circular Polarizer is not multicoated at all. We used to carry TMC (Tiffen multicoated) filters but found no significant difference in their light transmission and also that the coating could be easily damaged, resulting in poorer performance. In any case, multicoating is a proprietary process, and we seriously doubt that any lens or filter manufacturer will tell you the exact nature and composition of their coating layers."

Don't know. My concern is not if it will dissolve the paint, it would be if it would damage the shoe. It is great stuff all around, so I might pick it up and try on a tiny section of the least valuable shoe. Let it sit for a minute, then check surface. For example with plastics, it will start to dissolve the plastic, so it will cause a haze on the surface. (nifty way to get "frosted" plastic lenses). Sorry I can't be more help.
