Photographing solar eclipses and ultra-bright light sources can be extremely dangerous. This filter reduces light values by 9 stops to less than 1/500th of its original intensity and allows safe photography.
It can also be used to achieve super slow shutter speeds in daylight to render moving subjects invisible, and will enable you to use slow shutter speeds, especially with high speed films, to record movement in subjects such as waterfalls, clouds, vehicles, etc.
It will also decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. And this filter allows you to decrease the effective ISO of high speed film (above ISO 400) so it can be used outdoors in bright situations.
Neutral Density filters have no effect on color balance, appear grey and reduce the amount of light reaching the film. Multi-coating minimizes reflection at the filter surfaces which reduces flare as well as ghosting.

Best ND Filter I Have.
I uesd to take long exposure without ND filter and not satistied. When I ordered this filter with Adorama and tried it the first time the photos I made are very satisfactory. It is affordable, and durable. The only hard thing is you have to focus then attach the filter to get a sharp image.

functional but poor construction
First time I go out to use it, the metal washer, or fitting, or whatever it is called, that is in place to hold the glass in place, begins to unravel. How much did I spend on this filter? No, it shouldn't fail me the very first time I use it.

First time I go out to use it, the metal washer, or fitting, or whatever it is called, that is in place to hold the glass in place, begins to unravel. How much did I spend on this filter?

Hoya definitely has a quality control issue--this has happened to other filters, but at least those other filters lasted a while before it started to happen. The only reason this product is receiving two stars instead of one is because, if the construction were sound, the glass element itself would perform perfectly. Hoya address your quality control issues.

This is my second review and I am correcting the first one. It turned out that the red haze appearing on the image is cause by a light leak from the viewfinder. So I tried covering it with my black gloves. All images are shot at f/22. Those images with the silky smooth water flowing without the red haze are the ones wherein I covered the viewfinder. Thanks to a friend of mine who gave me the tip and heaven sent, genius extraordinaire Jim Ramsay!
I tested this today and most of my images are like this. emailed Adorama and waiting for reply. I want a replacement. Maybe it's just mine that is a bad batch
I've used this product a couple of times at the beach. Was able to get a nice blurry effect of the water. The only thing you need to watch out for is to not touch the filter directly with your fingers because it will make it harder to remove the spot. The glass is very delicate and easily dirtied.
Still learning how to use the filter but I love the possibilities it affords for water effects.
Really helps me achieve the long exposure shots when the sun is shining bright
The density is enough to provide a really long exposure even in brighter conditions. This is excellent if you like a slow shutter on moving water. Double check your focusing with Live View. I also find that I need to double and sometimes triple the exposure time the meter comes up with (e.g. use 6 sec instead of 2 sec). My best results are at iso 100 to keep long exposure noise to a minimum.
I expected that any additional glass in front of my lens would degrade the image quality. but after a long hike and may waterfalls later I think this is one of the best things I ever bought. images have no detectable color cast or loss of sharpness and still max out the resolution of my 5D mkII sensor. The example photo was taken with Canon 28-70 f2.8L 15 sec exposure f7.1 ISO100
This product was not helpful at all
This filter is great. I found the need to prefocus the lens and then put the filter on. Also important to shoot in complete manual mode. Provides shorter times than my buddy's 10 stopper, but it's about 2/3 the price. Great value
I love this ND filter, Its another handy tool that every photographer should have in there camera bag...Im happy to say that I DEFINITELY got my moneys worth. One tip when using the ND filter, make sure you cover the viewfinder.
