The KatzEye™ 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 would 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 KatzEye screen will have NO effect on the functioning of the autofocus sensors of the camera and it is a direct replacement for the original.

Note: Light meter testing was performed on the D40 model only. While it is expected that results for the D40x And D60 will be very similar, users of these models are strongly encouraged to check the histogram of a test shot before beginning critical work.
The KatzEye™ focusing screen for the Nikon D40, D40x, & D60 is available exclusively in the KatzEye™ “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 KatzEye™ “Plus”. More information about the KatzEye™ “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 here. We will also include an installation tool to assist in the manipulation of the screen retaining wire, but the installer should still expect to provide their own tweezers, gloves, lens tissue, and other common items.
