Q
Will ND2-ND400 filter cause X Cross Shadow affects Ultra Wide-Angle Len Like Tamron SP 10-24mm VC or Tokina atx-i 11-16mm CF Len? Will the X Cross Shadow disappears if I use Wider Aperture as 10mm?
Answer Question
A
Yes, it can, The "X" cross shadow is a physical property of the filter itself, and it is caused by the amount of rotation between the two polarizing layers, not the aperture of your lens. The shadow appears at the filter's maximum density setting, regardless of whether your lens aperture is wide (f/2.8) or narrow (f/16).
