I spent the last couple of weeks making an adapter, out of "PE" pipe, for the Cokin universal adapter to attached to so as not to scratch the lens hood of my Nikon 14-24mm. I used a Cokin X-Pro 121 Gradual Grey G2 (ND8) for the test.
Here are the results..
HDR - 14mm@f/9
Vertical Panorama HDR - 14mm@f/16 - consists of a total of 15 separate shots
Just before sunrise - 16mm@f/10
I am please with the initial test results. There is no vignetting at 14mm which is good news. Additional tests required to see if vignetting occurs at 14mm when I stack 2 filters together.
