Adjustable ND Filter - Anybody use one ?

[dinners]

I was just wondering if anybody here uses an adjustable ND filter and if so are they any good ?

Lightcraft (link below) advertise them in Outdoor Photography magazine

Funnily enough ive just been reading their advert in Digital Photo. If you go down the page to the thread 'ND Filter for £2' one of the llast posts is about the Light Craft Filters as someone has 2 of them.

You can make a cheap one yourself, if you are not too worried about results.

The top left image is 1/200s , going down to 6s at bottom right


Or a 'real life' example, 15s to 240s (4 minutes). But I am using energy saving lights, if I had some decent ones, you might actually be able to see something!

I've been using a lightcraft mark II, its not bad, but to be honest I would buy fixed ones next time. The light craft works by using two polarised lenses, and I'm not convinced that this results in a uniform reduction of luminance across the spectrum or indeed the frame. However I have had quite nice results.

Yes. Completely useless IMHO. With anything approaching a wide angle lens, you get a dark cross pattern from corner to corner at higher levels of ND. All cross-polarisers do it, it's a technique used to vary the lights in video/movies, which doesn't work for our application. I sent mine straight back, and I'm not the only one.

On the other hand, the LightCraft ND500MC is excellent
