Vignetting When Using Filters

I'm in the market for an ND filter. I use Rokinon cine lenses of which I have a 16mm and looking to get the 10mm. My question is will buying a larger nd filter and using a step up ring eliminate vignetting? The lenses have 77mm threads and was thinking about purchasing 82mm filters. Also, step up rings vary greatly in price ($5 to$30 or so), is there any real difference?

It really depends on the lens, but I would stay away from variable ND filters if vignetting is something you are concerned about. I am slowly switching over to the Hoya ProND filters, which have a metalic ND coating that appears to be resistant against IR contamination. ( the regular ND filters often have IR light issues )

I think that is better using the vinaigrettes in post and no while are shooting.

Sometimes a bigger filter helps, but what you really want is a slim filter. They lack front threads, but they stick out less, so you're less likely to see them in the frame.

Step up rings tend to be a pain in the *** no matter how much you pay. But if you get the cheap ones, you won't feel as bad when you take the pliers to one.
