Thanks!

Great video!! helped me out a bunch!

I guess I'm not using the correct term though I've used polarizing filters for decades.
What I mean is that it is circular, the effect increases or decreases as you rotate it while looking thought the viewfinder. While watching the start of your video when you demonstrate, it looks as though the density is the same across the entire filter (including when you change the intensity) unlike a circular polarizer.
Thanks for sticking with me but I'm still not sure how it does what it does,

Good demo. Hard filter to use, I find that moving the ND ring upsets the PL setting.

Very, very helpful - Thanks!
I've heard lots of great things about this filter(s) but didn't know how it worked.
At the start of this video you show the effect when you rotate the filter. I still don't know how the entire filter changes density (Unlike graduated filters) but can see that it works and will feel confident in my purchase when I plunk down ~ $400.

@daddysbike it works because it's really two polarizers together... when you rotate them the polarizing lines align and cause the filter to darken. However, unlike using two standard polarizing filters, the Vari-N-Duo is designed as to not create strange artifacts or interfere with autofocus.

@drjay32
Thanks for your reply. Are the 2 filters graduated like my typical polarizers? if so the density would vary, would it not?

@daddysbike polarizing filters are never "graduated."
These are solid density filters.

I wish that you mention the vignetting effect of this filter.

@appacana only if you use it on a really wide lens.
