ND FILTER
Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.

I knew as soon as I opened the envelope I had bought a quality item. Inside the gorgeous black outer box is a round acrylic container which flips open at the press of a button. The Filter rests on its foam bed. It looks like quality, it feels like quality.

Anyone that shoots video using a DSLR knows about camera settings and the limitations this creates in brightly lit environments. This can become a bigger problem if, like me, you like to shoot with the aperture wide open on a fast lens. It was almost impossible to do outside scenes on brighter days. To say I’m very pleased is an understatement.

Pros:
High quality, no dreaded X or aberrations and it only cost £36. I expected a lens of this quality to cost much much more.

Cons:
To be honest, there aren’t any. No, I can’t put the lens cap on when the filter is in place, but it’s no big deal to unscrew it and place it back in its case.

I am just an amateur film maker so my word counts for nought among photographers. From a film maker’s point of view, however, this is a great bit of kit to have in your bag and for the money, you can’t go wrong.

I've bought and been disappointed with variable ND filters countless times. The problem is when on the upper end of the ND setting you get a very visible X on your footage ( not good ).

I expected the same from these - but NO!

I've used them with a variety of lenses from 12mm all the way up to 150mm and not once have I had an issue, neither have I experienced any colour cast issues.

I would prefer the filters to have an audible click when moving from one ND setting to the next, but saying that I have found the movement to be fuild with a well-built feel to the product.

I was going to buy one for each of my different lens sizes ( which would have cost me a lot ), instead I bought a set of step-down adaptors and just bought the biggest size. For the cost of one I now have a well made variable ND filter for all my lenses - I'm very happy!
