The KatzEye™ 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 would 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 KatzEye™ 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 KatzEye™ focusing screen for the Nikon D2H/D2Hs shows only a very minimal effect on light metering. In our testing, the KatzEye™ 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 KatzEye™ focusing screen for the Nikon D2H/D2Hs 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.
