ND Filter

I have a Pentax 645n with a Pentax FA 45mm-85mm Lens,I want to purchase a ND filter for it should I go for the screw in type or the square Lee type,I have heard that a B+W glass screw in filter would give the best results ?,also if I use my Lee grad filter as will as a screw in ND would it cause any vignetting?
Any advice would be greatly appreciated.

For ND filters screw-in is fine - if you want to stack them, go for the slim version. Haida is another manufacturer of very good ND filters that according to most reports and reviews are on par with B+W and Lee, but considerably cheaper. There is always a risk of vignetting when combining several filters, you can minimise it but going for slim versions and stacking as few filters as possible.

But if you already have a filter system (which I assume, because you wrote you have a Lee grad ND filter), then you're probably better off getting a square ND filter too and combining both. Whether that would result in vignetting depends on the size of the holder and the filters. If you don't have issues with vignetting on your current grad ND filter, then I doubt you would see any vignetting by just adding one more filter.

I generally use square filters for everything now.
Than way I just keep one filter holder and I don't have top worry about what's already screwed to the front of the lens.

Me too re using square filters and just get different adapter sizes for various lenses. I sometimes might combine a screw in polarizer with square ND or grad ND filters.
