The KatzEye™ focusing screen for the Nikon D200 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 on-demand grid lines will continue to function as intended.
Nikon D200 Viewfinder with Split Prism & Microprism Ring (Simulated)
The KatzEye™ focusing screen for the Nikon D200 has NO effect on existing viewfinder information. All viewfinder markings, including focusing points and on-demand grid lines will still function normally.
The KatzEye™ focusing screen for the Nikon D200 shows only a very minimal effect on light metering. In our testing, the KatzEye™ screen tested within factory tolerance in nearly all situations. 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 KatzEye™ focusing screen for the Nikon D200 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.
The KatzEye™ screen is a direct replacement for the original and no modifications to the camera are required. The installation requires no special tools or skills, but it does require working in tight spaces. If you are not confident in your vision or dexterity, professional installation might be advisable. For those users installing the screen themselves or for those taking the camera to a local shop, complete installation 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.
If you do not wish to perform the installation yourself and you do not have a trusted local shop, we’d be happy to install your new focusing screen for you here at KatzEye™ Optics. Please see the Installation Service page to order installation with your focusing screen. Installation service at KatzEye™ Optics costs $65, plus the cost of return shipping of your camera.
The original Nikon D200 screen is optimized for automatic focusing. As such, it is very bright, but it gives a very poor indication of DOF and has very little ‘snap’ (indication of when focus is achieved). The KatzEye™ screen is optimized for manual focus applications and has a much improved matte surface. The matte surface on the KatzEye™ screen is designed to give excellent DOF indication and a very sharp ‘snap’. However, because of this, the standard KatzEye™ screen for the D200 is slightly darker than the original Nikon screen, particularly at smaller apertures. If viewfinder brightness is a concern for you, consider the optional OptiBrite enhancement. With the OpitBrite treatment, the brightness of the KatzEye™ screen is comparable or slightly brighter than the standard Nikon screen. The OptiBrite treatment affects only the matte portion of the screen; it had no effect on the prism and the OptiBrite treatment will have no significant effect on light metering in the D200.

Although the Nikon D200 has very nice on-demand grid lines which remain functional with the KatzEye™ focusing screen, additional patterns can be added to the focusing screen if you require different composition aids. We can meet your needs with a variety of standard patterns of grid lines and crop guides or we can provide a custom pattern to your design. Please be aware that composition aid patterns added to the KatzEye™ focusing screen will be permanent and will not turn off like the in-camera grid lines.

All KatzEye™ focusing screens are custom made to order and are usually not available to ship the day the order is placed. As of 04/19/2014 production is running normally and most orders will be shipped in 4-6 business days from the date they were placed.
