Some test with the Nikon Nikkor zoom 17-35mm 2.8D ED, and a B+W Schneider circular polarizing filter. I had to stop down to much because of the bright light. So the image isn't superb.
My SGBlade RR 2 can handle f4/5.6 stop max. So I have to order the RR 1 that will go down to f22 and comes with less bokeh and softness. Most of the footage is shot @ 17mm (really wide) and it will give some edge distortion, and vignetting.
No grading and no corrections.
When I have the RR 1, I will be doing some more testing with this awesome lens.
