Anyone looking into getting a variable ND filter knows that they are not cheap. I thought I would take a chance with Rainbow and boy am I glad I did! The product not only works as advertised it also is one of the most neutral ND filters I have ever tried. I was so pleasantly surprised I order another one for my 55mm lenses. This product I can recommend with good conscience.

I was shopping for a 10 stop ND a couple of months back and couldn't find one in stock anywhere so bought this filter instead. For most of the work I was planning to do, 8 stops would be perfectly sufficient. Testing the filter, however, I find that it works well up to about 6 stops of reduction (as measured on the filter's rotating scale) but above this, I start to see very nasty artifacting in the image with bright and dark areas easily visible. I'll hang on to it for use in the lower part of its range but I've bought a solid 10 stop ND since too. If you're looking for a really dark variable ND, I suspect it does actually pay to go with one of the more expensive options.

This is an interesting product which appears to be two polarized filters merged together. One of the polarizers is fixed to the filter threads while the other one can rotate, allowing the two filters to change phase in relation to each other. As the two align, most of the light passes through, and as they approach 90° to each other, nearly all of the light is blocked.

It may be possible to buy two 77mm polarizers (for under $20) and achieve the same effect, although I have not tried this (yet!) =).

As opposed to a true ND filter, these are polarizers so you will have the polarizing effect in addition to the ND light-lowering effect, whether you want it or not. Rotating the second filter alows adjustment of the light-blocking level, but since the 1st filter is fixed to the threads, you will have to keep it loose and rotate the WHOLE filter assembly in order to adjust the polarizing effect. This could be tricky if you need to get both effects just right.

The only other issue I found is that the glass is not terribly flat, and I noticed quite a bit of distortion (heatwave effect) as I rotated the entire filter in front of my eye (not mounted to the camera). I have not tested to see if this distortion makes a noticeable difference in the images or not. Some testing is certainly in order.

Overall, this is a neat product, with a few unexpected and potentially useful hitches, but perhaps a bit pricy considering alternative methods (buying two much cheaper polarizers) and the not-so-flat glass used in the product. So there you have it!

This product releases some kind of oil from it. It seems to be cheaply built because of that. I hope that the oil doesn't go between the glasses. It's annoying to be cleaning the oil all the time.

Also didn't liked that they didn't specified that the 77mm version actually increases to 82mm, so my 77mm cap doesn't fit. Otherwise I would have bought a 82mm cap together with this.
