A: The, B+W 100 x 100mm XS-Pro MRC-Nano 815 ND 4.5 Filter (15-Stop) is one of the better ND filters. And is very good for low color cast. And yes, it will fit into the Lee 100mm holders. Like lee filters the filter is 2mm thick.

Q: 4. with an ultra-wide angle lens (i.e. Canon 16-35mm F4L with a full frame camera), do you get the dreaded X show up and if so at what density does it show up?

A: The X you can sometimes pick up in the image with a variable ND filter is caused most of the time by variable ND filters that go over 7-8 stops and lower quality ones.The B+W filter is fine. The one thing you might pick up is when set to the widest setting on that lens, 16mm you might pick up some vignette. And that is going to happen with that lens with most filters because of how wide it can go. The filter is designed with a thinner frame so it should be somewhat minimal.
