Focus Shift in Camera Filters

Focus Shift in Camera Filters

  • Filters of any considerable thickness present a minor focusing problem. They shift the focus of the lens by one-third of the filter thickness. Used in front of the lens they shift it toward the subject. In normal use this shift can be ignored, becoming significant only at close focusing distances, as in photomicrography.

  • The best solution to the focus shift problem is simply to make the final focus after the filters are in place, if it is possible. In high-magnification work it is best to avoid the problem entirely by filtering between the light source and the subject, rather than at the camera lens.
