What about the extinction ratio of the filter?

Hello. I'm not sure what you're referring to with the "extinction ratio" of the filter. If you are perhaps referring to the filter factor - i.e. the amount of f-stop exposure compensation when using the filter with a manual exposure camera or light meter - I believe for this particular filter that value is 1. Tiffen has a small section on Filter Factors you may find helpful here: http://www.tiffen.com/tiffen_edu_camera_filters.html Please let us know if there is anything else we can assist with.

Good Nicole! This filter is hero3 +, I would remind you that the LCD only came a back door and not change the complete housing. The hero3 brought the case that enduring 60 meters and is clearly distinguishable by the small screws on the lens. So I recommend that before buying the filter look good in the photos and the model of your camera body. Filter is 100% worth, improves the image severely! I hope resolve you doubts!

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

It is translucent and will filter all colors out, except the color it is. However, it should not affect any focal properties.

I still have the box. I will see if I can find information.http://www.pegasuslighting.com/optivex-uv-filter.htmllook at this one

It is best to not use a clear filter. A UV/clear filter can indeed affect image quality, particularly when the sun is in the frame. This can result in some rather un-attractive flare and blobs. As long as you keep the hood on when shooting, the front element should be protected, unless you are unreasonably hard with your gear.

Who knows? There are better filters out there. The one I got did not come with any paper work that details its campliblities. A monolithic filter or the ones that go in a Berky are good filters. They list exactly what they filter out.

Depends on the environment you are in. You can tell by how full the filters appear. That would be my guess.

You should probably call the manufacturer. A quick search of Adorama and B&H; does not reveal the answer (both sites carry this filter).

Thank you so much for the information. I bought some 58mm filters and an adapter and have held them in front. I will look for some 37mm so I can do your workaround. Thank you for the information.

I'm not much a camera tech so I can't authoritatively answer your question, but I have my polarizing filter on top of a regular daylight filter on my Nikon D40.

I have 3 sets of ND filters and each set consists of a ND.8, .4 & .2..... therefore by combining filters you would achieve (.8+.2) 1.0 or (.8+.4) 1.2 or (.8+.4+.2) 1.4

The size will be the size of lenses filter diameter. The hood should be checked at various focal lengths to determine if image cut-off occurs.

The filter has two sides: glossy and matte. The glossy side is quite reflective. The matte side is far less reflective, but does slightly increase the glare reflecting off my monitor. This is especially apparent when the background is black or a dark color. This is something that could be improved in future iterations. Still, as it reduces the harsh light emanating from the monitor, it is totally worth it!

I relatively sure it is zero. In fact, I'm positive. Most all privacy filters I have encountered are very low on RAM; it's difficult to fit RAM on a 2mm piece of film. It does however have very nice polarization and a shiny gold surface, if you choose that side. I rated this filter very high, but now I am having buyers remorse thinking I should probably have bought one with more RAM.

I don't use clear filters because they can have a distorting. I use my polarizer and ND filters but that's it.

Carefully read the specs! Some units will specify new electronic processing to almost virtually eliminate the blur you are concerned about; I noticed it right away in the perceptual clarity...you pay a little more but the difference is worth it.
