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.

I have one of these. I use it TI monitor the effectiveness of my RO filter module. It works great and it is cheap. Since I am not a testing lab, I can not say that it has 1 ppm resolution, but I can tell you it very well may.

The macro ability is almost too good. I was disapointed, for a while there, that it would not focus, at times, with a Polaroid and UV filters. I later realized that it would focus on any dust on the filter (especially when the sun is not in your back).

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!

If you are referring to the filter, it is not very audible, I would not expect a neighbor to hear it.

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

I didn't experience any lose of sharpness. However I stack This filter with a CPL Filter. And also I didn't experience any problems. Basically I shoot Landscapes with small apertures, so usually the depth of field is wide and everything seems sharp and in focus.

I would expect that you would notice a reduction in glare, if you tune the orientation of the filter sheet. Be aware that there is an overall reduction of light through the sheet, even when it is not affecting the glare.

I don't see it because it does not happen with the kind of photography I'm into. If you like using 8-10 stop ND filters to do long exposures in daylight, or like to open your aperture all the way and point directly at the sun, then you will have issues with it. It will not affect most users in normal practical situations.

Hello BenYou can use any of the ND filters, 2, 4, 8, 16 or 32 depending on how bright it is. ND filters darken the scene by certain amount of stops depending on the ND filter used.Polarizing filters are often used to eliminate reflections though you can still use it for bright scenes. None of the rest would be useful for what you're doing (underwater, macro or UV).

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.

Alex, I actually shoot with it a lot outdoors as it cuts any glare and deepens contrast. Great filter!

Depends on the lens attached to the camera. If you are looking at the end you would attach the filter to, you should see a zero with a slash through it followed or preceded by the size in millimeters.

The filter is not very removable once in place. But it is not a particularly dark filter. If you have your screen brightness between middle and High you wont even notice its in place even from ext ream angles. Once the brightness hits about 1/3rd it becomes a decent privacy filter, but no where near as good as the previous 3M filters I have used. I was quite disappointed with this one.

this shouldn't interfere with any portion of focusing either in or out of focus regions. If you put this to its fullest setting you will be left with a very close to black out filter. What you will notice its that you will probably have areas off uneven filtering the darker you set the filter.

I threw mine away it was so bad. There is no way that I would recommend this filter to anyone. A very clear dark X banding was across the frame. Don't waste your money on it. The banding completely ruined shots that I used it for on some waterfalls (which is what I bought it for).

Hello. Sadly after buying it I noticed that it is inappropriate to use filters, leaves a shadow around the image
