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.

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.

What kind of effect are you looking for? These filters are not designed to make big changes in color, they are to make blues a little bluer, greens a little greener and so on. As an example, if the sky is a lite blue , the 1/2 blue filter can be set to make the sky a slightly more blue. The "UV" filter removes some glare when used in direct sun light, Fluorescent lighting tends to change the color temperature and not in a good way, the use of the "FLD" filter can make the lighting look more like Tungsten lighting. The "CPL" filter is maybe the hardest filter to use, it is hard to see the difference that rotating the dial makes. The "CPL" filter is a "Polarizing" filter, fishermen use "Polarizing Sunglasses to be able to see in to the water and see the fish. The "CPL" filter helps in high glare places like looking thru a window in direct sun light. To see how it works, go to a river or lake and hold the filter up to one eye with one hand and rotate the dial with the other while looking into the water. The star filters require sharp/ strong points of light try setting up Xmas lights around a window or door and view it thru the filter, the number stands for the number of arms that extend out. (star-4 = four arms/ lines, star-6 =6, star-8 =8) The main thing to remember is that the view finder and or monitor on todays digital cameras are small and it is difficult to see the changes these filters make, I use a 26" HD high definition (at least 1080p) monitor using a HDMI cable thru the video out on my Canon Rebel T4i Camera. I hope this helps.

Agreed - Amazon doesn't do enough to describe the product. That said, the photo they supply is accurate, as the filters that come with it are the 0.6, 0.9, and the 1.2 neutral density filters. It was exactly what I was looking for and despite the lack of information, I'm very happy with the purchase. Hope that helps.

Here is the link to the requested filter. http://www.amazon.com/gp/product/B004WDQ2W6

Yes. I have been able to stack all the filters all at once and use it to get very close to my subject. But at that range, the shadow of the camera obscures the subject. In addition tothat, chromatic abberation (purple fringing) gets worse as more close up filters are added. the +10 alone exhibits a lot of purple fringing. I hope this helps.

I haven't been messing around much, but with my 18-55 mm I got a bit better results, and of course, playing with the filter itself to find the best position for what I am shooting. the filters seem to be a very subtle change. I have had darker gradient filters in the past, and still have them, but they don't fit on my Rebel.

I would thank that you would. Have to read all of the spectra for each model # and compare closely, could be an extra coating on the linse, could be minimem focal distence just compare very closely

This particular technology is proprietary and the manufacturer doesn't give a number. In marine applications, a 10μ filter is usual for fuel-water separation.

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

Certainly not for me, I could not justify the reduced light transmission of the APD filter. I use this often at f/1.2 and the APD version may be worse than f/1.4, some say 3/4 an f stop. Personally I thought about changing until I saw the impact on light and a rendering that i did not prefer.

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

This filter reduces the amount of light hitting the sensor so allows you to increase the exposure time obtaining blurred moving subjects. e.g. Use it with a tripod to photograph the sea or rivers and streams like in this pic http://500px.com/photo/3539311.

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.

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

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.
