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.

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.

We used them in s filter. I would worry about it not dissolving properly if I just threw it in.

Not really, although I have a tiffen 62mm uv filter primarily to protect the lens against dirt and mist. I have been happy with image quality and lens versatility. I also have used a tiffen 62mm circular polarizer, but it has rarely been necessary. The lens hood works well to reduce glare and "ghosting". Hope this helps.

I have no idea. I guess it would depend on the composition of the filter that you have. This is good stuff.

I use the clear UV filter to protect the lens from any contact that would harm the first lens element. Lenses have coatings that can get worn away from numerous cleanings and improper handling. The polarizing filter would protect the lens, but I wouldn't want to use it for every shot. I use mine to reduce reflection in glass, darken the sky and modify contrast, depending upon the situation.

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.

I attach low cost clear filters on all of my lenses for protection from dusts, deposits and finger prints on the glass. Thus, I have never wiped, never contacted the lens glass. I clean the filters by using water from reverse osmosis in my kitchen whenever I find deposits and/or dusts on the filter glass. To my tests, I do not see my low cost filters make any adverse effects on the pictures taken by myself.

I erroniouslly purchased the non coated version for my wife. She is a sunrise/sunset photographer. The non coated version allowed significant lense flare when pointed into the sun. While on vacation, we met another photographer who had the coated UVA filter. She had the same problem we did, only bought the MRC and hasn't had a problem since. I have since purchased a B+W UVA MRC filter for her, among other stupidly expensive filters, but I have wasted enough money buying items "on the cheap" for her hobby to know that you get what you pay for. I buy B+W exclusively for her 5D Mk ii and L series lenses.

Mine just say JAPAN OPTICS. They do not seem to be multi-coated. I use the polarized filter to protect the lens, and it does a fine job of that at a low price. I would recommend a more expensive single filter for more serious work.

I haven't had any problems with rain or water from my cooler getting on it, but some other reviewers said water would get on the inside of the lens but personally I have not had that problem yet.

I use a Red Polarizing filter for dive, no for surf. I put the filter in the water,and check for bubbles before attach it.

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.

Please tell me more about this. We stopped using these filters when we noticed that when we boil the filtered water it becomes cloudy and stays cloudy. Our unfiltered city water does not turn cloudy when we boil it. Something is in the filters and is not noticeable until after the water is boiled. ThanksDavid

Hi Nora it will protect the lens elements from rain droplets, dust and scratches. but it can"t be used underwater if that's what you are asking, water droplets will mark it but can be wiped off with lens tissue and if it gets scratched it's cheaper to replace than a lens hope this helps.

Yes it is Multicoated. You will see on the ring that is says "Hoya HMC". The HMC is Hoya's designatin for "Hoya Multi Coated". This is a great filter and find myself using it more and more all the time for long exposure shots.

Not sure I can be of much help.....I haven't tested all of the "elements" that you listed as threats to the lens - really haven't experienced extreme conditions under rain or sea water spray - some, but nothing severe. Living in Oklahoma I know my lens is exposed to dust. All I can say is that there is no apparent affect on my lens or camera to this point...but then both are still relatively new. I trust Pentax to perform as promised. My K30 is my "fourth generation" of Pentax - Spotmatic, ME Super, Super Program, K30.
