77mm Fader ND Filter
 

I'm about to purchase a 77mm Fader ND filter which fits these three lenses:

17-40mm F4L
24-105mm F4L
EF-S 10-22mm F3.5

Does anyone know if this filter vignettes with any of these lenses and, if it does, how much? Thanks!

I can't comment on those lenses, but I can say that I went the cheaper route and bought a linear polarizer to stack with my existing 72mm circular polarizer and use it as a variable ND on my 28-135 lens. It works fine. If you have concerns about vignetting, why not just purchase a step up ring and the next size up of the filter you want? 77 to 82mm step up rings are less than $10 at B&H I believe.

The 77mm Fader ND is $108.

Thanks for the advice, but I currently don't have any 82mm filters. I'd need to purchase the step-up ring and both of the 82mm polarizing filters. How much would that cost? (I suspect far more than $108)

Where do you purchase a Fader ND? I can only find normal ND filters on B&H and Google searching only shows blog posts and discussion topics about them (including this thread).

I can't imagine encountering any vignetting with the 7D due to it's 1.6x crop.

You'd only have to worry about vignetting with EF-S lenses. But they usually have small thread diameters, so you'd be using a step up to 77mm, before the Fader ND. Vignetting is highly unlikely.

The 77mm Fader ND is basically an 82mm filter in a 77mm step-down ring so I would be amazed if there was any vignetting with the 1.6X crop of the 7D.

Has anyone here tried this fader ND? What is the quality like?

Like it. A lot. Like a second iris control on front of the camera. Shot all day with it and it worked great: excellent quality and no vignetting on a Canon 24-105mm. Only thing is that the lens hood has to go on the lens after the filter because of the 82mm filter size.

OK, thanks Nate.

Nate what hood do you have that fits over it?

Stock hood that comes with Canon 24-105mm F4L. Model number is EW-83H.

I might be more clear - the hood needs to go on first, then you need to screw on the filter somehow. My earlier post was misleading, my apologies, the lens has to go on after the hood.

I wonder how the Fader ND compares to the Singh-Ray. That's the one I was thinking of getting, along with a 58 to 77mm step up.

The Fader ND will work on all the lenses you list but on the 10-22 you might get some vignetting especially if using the camera for stills. In video the 16x9 frame crop should cut most of the vignette out if there is any.
