The Katz Eye™ focusing screen for the Nikon D2H/D2Hs 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 for the original, 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. The screen will have NO effect on the functioning of the autofocus sensors of the camera and the AF point indicators will continue to function as normal.
Viewfinder Markings The Katz Eye™ focusing screen for the Nikon D2H/D2Hs has no effect on existing viewfinder information. All active viewfinder information, including the focusing points will still function normally.
Metering Information The Katz Eye™ focusing screen for the Nikon D2H/D2Hs shows only a very minimal effect on light metering. In our testing, the Katz Eye™ screen tested within +/- 1/3 stop of nominal. The only exception is when using spot metering mode with lenses having a maximum aperture slower than f3.5 (higher numerical f-stop). With lenses slower than f3.5, it is advisable to use either centerweighted average metering or matrix metering to preserve accurate meter response. In the event that spot metering mode must be used with a slow lens, it is advisable to set an appropriate exposure compensation by reading the histogram of a test shot.
The “Plus” Prism The Katz Eye™ focusing screen for the Nikon D2H/D2Hs 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.

Brightness Enhancement
Like all screens made by Katz Eye Optics, the D2H/D2Hs screen can be OptiBrite brightness enhanced for the ultimate appearance. The OptiBrite treatment affects only the matte portion of the screen; it does not change the prism in any way and it will have no significant effect on light metering in the D2X.
