I have one of those thin-mount polarizer filters and was wondering if there would be a problem if I screwed a neutral density filter on first and then screw the polarizer filter on second?
The only problems I've run into are vignetting and light reflection between the filters. If you don't get the vignetting, all you have to do is shade the front of the lens to control light. The "problem" with that is that my B+W Schneider thing polarizer is so thin because it doesn't have front threads. Not a problem really, because I just use my hand to shade the lens.
BTW- Depending on brands, watch for color shifts when stacking a pola and an ND. Some give a decided olive cast, but in this era of digital editing, another problem surmounted.
You might also try screwing them on together before screwing on your lens. It is easier to see the amount of the polarizing effect that way. Also, be weary they could get stuck together. I practically ruined a polarizer a couple of years ago doing just that. I shook the glass loose by trying to get them separated.
I agree with the comment about getting them stuck together. I've gotten mine stuck together before.
I always get some vignetting on my Sigma 10-20 mm lens with the stacked filters, but if you're not that wide then you may not have a problem. Also you have a thin ring, so maybe you won't have any problem with vignetting. The other thing is that the camera viewfinder probably only displays about 95% of what the camera takes, so you may get vignetting and not know it until post-processing.
I'm probably not saying anything here you didn't already know. Good luck.
