Found this searching around and wondering if anyone has tested it yet... http://www.ebay.com/itm/ND100-/400917213014?rmvSB=true Seems a bit overpriced to me....

What does the ND filter do? Is it similar to a polarized lens, which I have in my sunglasses and works beautifully.

I am not a professional photographer but from what I have studied..

A Neutral Density filter allows a photographer to control the exposure in an image very easily. The filter stops light reaching the camera sensor, therefore allowing us to leave the camera with a higher aperture for a longer amount of time.
Instead of changing the aperture to reduce the amount of light in the image, we simply add on a ND filter, then adjust the exposure to the amount we want. It is easy and very effective, plus we can still set the aperture to a low value for sharper images, or wide open for a shallow DOF.
I have found it to help when filming on bright sunny days when using them on my P2 Vision Plus

That is extremely overpriced"

If it is truly an ND 100 then it is waaaayyyy to dark!  We have a set of ND filters for our Inspire 1 and the highest we have is ND 64. Out of the set the ND8 and ND 16 are the best.

Using an ND filter forces the camera to shoot at a slower shutter speed which can reduce the "Jello" effect in some cases.  It's not clear if the P3 can benefit from an ND or not.

It absolutely can.

I'd be concerned with using using heavy contraptions like that. There are much lighter alternatives. They may not be 100% as high quality - but they won't hurt the gimbal.

I'll hopefully have something to offer to the community soon. I already use ND-filters for my Phantom 3 Professional. The main goal is to get better motion-blur for more natural looking smooth 30 (or lower) fps video. It can also help with jello that is also caused/made worse by high shutter speeds.

My Phantom arrives tomorrow.  I have not actually examined the camera yet.
I would be concerend about adding too much weight to the front of the camera lens.  It will throw off the balance of the camera and make the stabilizer gymbal draw more power and possibly overheat.

Someone else mentioned that the clear glass filter unscrews from the front of camera?  If so you might be able to put a thin & inexpensive  "gel" type ND filter behind the glass and screw it back on?  It would weigh almost nothing.

Just an idea.

Very interesting, thanks for the info.

The "outer lens" does look like it is a part but itself. But I have (gently) tried to unscrew, and I can't. Also, I've not heard or seen anyone do this as of yet.

I'm making some perfectly circular ND-filters of the gel-type that attaches with a circular glue (double sided tape) so they will be easy to take on and off. Furthermore they will ad a bit of protection for the glas. I will start to ship sets of these worldwide soon. They will be inexpensive and very light in weight.

I've used them with my P2V+ and my P3Pro. It is like putting a pair of sunglasses on the camera. You don't notice it much in the video except for the lower shutterspeed which helps with jello and adds motion blur more natural motion. The drawbacks are minor - for example at certain angles there can be some extra lens flares. Also, they should not be on when doing photography, since they increase the shutterspeed. You rarely want motion blur in your stills

It's ragecam, all their stuff is highly overpriced and shitty quality on top. I ordered an ND filter for my Hero 3 from them and regret spending that much money on it. It fell apart after a couple of weeks and they refused to replace it, even though it was still under warranty.

Don't buy anything from those guys!

It does appear that the front lens cover does unscrew.  Check out this thread.  Post #5.

Just cut a piece of ND gel and place it behind the glass cover and screw it back on.  Instant ND filter for about $5.

Ive unscrewed mine , quite easy , worth looking into gel ND filter , thanks

Hi FantomDK, do you have a link to the ND Gel  you are using please, very interested in getting some

is ND64 too dark for phantom 3?  please advise.

In my opinion it is. Look on the Inspire 1 forum. Our members tested our Inspire 1 filters that we got from Renaat. The darker you go the more you have color correct in post.

Yes, that will be way too dark. 0.9ND (ND8) is the darkest I use so far.

It is not so much that you'd have to color correct afterwards (in fact you shouldn't have to at all because of the ND filter - thats the point - it is neutral (grey)). If you use one of those very strong NDs it would have to lower the shutterspeed to say 1 second - meaning it would be a blurry mess

Our goal for the ND-filters are to lower to shutter speed to about 2x the framerate, to get a nice and natural amount of motion blur for fluid motion (and to avoid jello if props are a bit unbalanced or other problems). So if shooting 30FPS video it is a rule of thumb to go for 60 shutterspeed.

When doing stills it can be an idea not to use an ND-filter because you usually don't want motionblur in stills.
Edit: Take a look at the Wikipedia-page about ND-filters  As you can see, and ND64 only lets about 1.5% of the light thru - so thats a pretty dark (black) filter   I think those strong filters are used for long-exposure-shots - where you get this silky water if shooting water flowing - or soft clouds, if shooting clouds. It would be for speciality-uses on a quadcopter
