The ND values of the three filters are different. In order to avoid the phenomenon of suitable exposure for wide-angle cameras and medium telephoto cameras and underexposure for telephoto cameras, the light reduction values of the three lenses are slightly different. For example: Wide angle ND8, medium telephoto ND8, telephoto for ND0 Wide angle ND16, medium telephoto ND16, telephoto ND8 Wide angle ND32, medium telephoto ND32, telephoto ND16 Wide angle ND64, medium telephoto ND64, telephoto ND3 ND&PL filters also have the same ND value distribution as ND filters

This is a Canon to micro 4/3 systems like the current Panasonic and Olympus models. Unless Nikon has the same mount, it will not work. 

hi, your lens mount is AF mount, and your canon 5d mark 3 is EF mount, you need a nikon-EOS adapter ring, the eos-L/M is not fit 

I dont believe so since i bought it for a Canon 80d. I didnt buy it for a Nikon camera. You will likely need a different adapter
