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. 

Beauty In Nature

Good value

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!

Case Study: Hoya NDX400 Red Haze Mystery

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.

Does what it's supposed to

Still learning how to use the filter but I love the possibilities it affords for water effects.

Hoya 77mm Neutral Density ND-400 X

Really helps me achieve the long exposure shots when the sun is shining bright

Great for long exposure on a sunny day

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.

Excellent For Slow Shutter Water

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

No loss light reduction

Look around before you buy

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

Hoya 9 stop filter

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.

Great for special effects, very useful!

I've been using the same filter but of a smaller size 67mm on Nikon D90 and 18-105mm lens, when i upgraded my gear to Nikon D800 and 24-70mm 2.8 i bought the 77mm filter to fit the new lens. And it turn out its as good as the smaller size.
A gr8 ND filter to get long exposure shots in the mid of the day.

Never get better

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.

Best ND Filter I Have.

I bought it for the eclipse on the west coast. It worked well but it was still not dark enough to do a timelapse.  I will now use it for daylight Landscapes to smooth the water and clouds.

ND-400 Review

Be warned! This is an extemely dark ND filter. I purchased it to photograph dams and such that are in direct sunlight and it works perfectly for that situation. Might be TOO DARK for subjects under a thick forest canopy.

Outstanding Value

The glass element popped out the first time i used this filter. Sent it to Hoya for repair under warranty. They replaced it but the washer that holds the glass element in place is warped. This isn't the only filter that weak construction was an issue.

Quality Control issue

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. 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.

functional but poor construction

Great for long exposures. Highly recommended!!

Great extreme density neutral filter

Great filter. You can't make a mistake with this one!

Perfect for long exposures, extremely bright shots, or losing people/vehicles/etc in landscape shots.  Not everyone needs this, but if you this is a valuable filter to own.

Great for special effects...

I use for long exposures in very bright conditions and it works very well
