I want to create a DIY adjustable ND filter by stacking a Marumi DHG Super Circular Polarizer and a linear polarizer on an 58-77 adapter. Will this cause vignetting on this lense? Anyone tried this?
 
Not sure how much the LPL you're looking at costs, but for not much more than a 77mm Marumi CPL, you can get a 77mm Marumi Variable ND filter. I'm using a DIY variable ND (from 2 LPLs), and while the quality is good, it's thicker and more of a hassle to setup and use (because you have 2 rotating rings to work with). If thickness is a concern, I'd take a look at an all-in-one option.
 
I had a 12mm Oly that just started vignetting at 12mm step-up ring and two NDs which were also 77mm. So you could be just fine at 16mm.
 
Thanks Jack.

Jive - yeh but with this combo i have BOTH variable ND and a good polarizer for one money, so its 1/3 cheaper :-)
