Optical anti aliasing filter
WebApr 30, 2015 · Both cameras are equipped with a filter, but in the 5DS R it is incapacitated. An anti-aliasing filter blurs the image in a controlled way using a phenomenon known as birefringence. This occurs in some crystalline materials where the index of refraction depends on the polarisation of light.
