So I will soon have a lens that will vignette with two filters stacked, most likely even with the thinnest filters available. I do waterfall photography and use a polarizer and ND in combination most of the time. The polarizer takes the glare off the water, rocks, foliage, etc but I usually need and .6 ND to get me to shutter speed and aperture I want.
So the question I have is whether anyone knows if you disassemble a ND filter, whether the threads in the ring that holds the glass are the same as you'd find on the front of the polarizer. I'm thinking of removing the glass from the ND filter and threading it directly into the front of the polarizer. It "looks" like it's the right diameter, but I don't know if the threads are different. That should take me from about 8mm down to 5mm and I don't believe I'll have any vignetting.
I don't have the lens in hand yet, so it's possible when I stack them and stop down to f/11 that the vignetting will disappear, but I'm somewhat doubtful.
Anyone ever do anything like this?
