The Katz Eye™ focusing screen for the Nikon D40, D40x, & D60 is a laser matte with a split prism circle and a microprism collar, very similar to the one you’d find in many classic SLRs. It is a direct replacement with no modifications required to the camera at all. The split prism with microprism ring is a great combination for focusing in a variety of situations and will be particularly helpful when using the D40 with non-AFS lenses. The Katz Eye screen will have NO effect on the functioning of the autofocus sensors of the camera and it is a direct replacement for the original.

The Katz Eye™ focusing screen for the Nikon D40, D40x, & D60 is available exclusively in the Katz Eye™ “Plus” version . The “Plus” version has a unique prism design which delays the prism ‘blackout’ phenomenon until well after f11. Ordinary split prisms will black out by about f5.6, rendering them difficult to use with slower zoom lenses, teleconverters, or in extreme macro photography... but not the Katz Eye™ “Plus”. More information about the Katz Eye™ “Plus” can be found here.
Installation is straightforward. It does require care and a steady hand, but NO modifications to the camera are required. Complete instructions, with plenty of photos, are available for download and the link will be included with your purchase. We will also include an installation tool to assist in the manipulation of the screen retaining wire, but the installer should still expect provide their own tweezers, gloves, lens tissue, and other common items.
