Like many of the FX filters we offer at Prism Lens FX, the Macro FX Filter was designed to solve a problem. Many of our favorite go to lenses have a close focus, limiting your ability to get close up macro shots. That is unless you want to pick up an expensive macro or probe lens, but that will set you back at least $1-2K. The Macro FX Filter solves this problem allowing you to keep your favorite lens on your camera, and when you need to get a close up detail shot, throw on the Macro FX Filter instead!
