What is the Function of the Different Parts of the KatzEye™ Screen?
  • The split prism portion of the focusing aid breaks lines that cross the centerline of the circle. When objects are out of focus, the image in the top half of the prism will be shifted left or right compared to the image in the bottom half of the prism. To focus with the split, just turn the focus ring on the lens until the two halves of the prism line up the target object.

  • The microprism collar (the donut shaped area around the split circle) is a cluster of miniature split prism pairs. When they are out of focus, they break up the image in a sort of shimmery way. To focus using the microprisms, just turn the focus ring until the shimmery effect is minimized.

  • The matte portion of the KatzEye™ screen (everything outside the prisms) is also much better than most OEM screens, so in situations where neither prism is helpful, you can always just use the matte area to make the target look in focus.
