Very little magenta cast. Very accurate 10 stop rating. Slight vignette in the corners. How I tested. I set up my D850 camera with a 17-35mm f/2.8 Tamron lens set at 17mm 3 feet in front of white seamless paper. I placed 2 Einstien lights bare bulb on either side of the camera. At the lowest power setting using an incedent flash meter to set the reading at f/4 - ISO 100 across the image as best I could and took a control shot. I then added the M10 filter holder using the 77mm mounting ring, added the ND filter and increased the output of the Einstien flash units by 8 stops, and increased the ISO to 400 for a combined 10 stop adjustment. I then took another image with the ND filter in place. I imported both images into LightRoom. Using the reference image feature to compare the exposure values. Center values are within 0.5% Edge values are within 3.0% Corner Values are within 6.0% First I can say there is using the M10 holder there is NO corner cutting or gross vignette like I get when stacking round filters. There is a slight magenta cast in the corners, and can be removed with a -2 adjustement to the tint slider. Accurate, effective and glass so it will not distort the way a resin filter can.

Two things to look for in buying a ND filter is price and that the filter is multi coated. The Haida filter is priced much better than similar filters plus most of the other filters are not multi coated. It should be an easy decision
