Q: 2. How much vignetting would this lens have on a tokina 11-16 lens on a Nikon D7200?

A: Your camera body is not full frame and has a 1.5x magnification factor. As a result your 11-16mm lens when used on this body is essentially a 16.5mm -24mm lens. There should be no vignetting given these focal lengths when using a standard CP filter. However, if you are concerned Tiffen does make a low profile filter to avoid vignetting: https://www.bhphotovideo.com/c/product/163451-REG/Tiffen_77WIDCP_77mm_Circular_Polarizing_Wide.html
