Katz Eye for D300

[kennethw]

Just got a note from Keoptics that the Split Screen for the D300 is now out, it is the SAME as that for the D200. Unfortunately, I sold my D200 Katz Eye, so need to order a new one.

Anyone going to start an MO?

Got this info from Katz Eye Optics website.

What Does a Split Prism Focusing Screen Do?
A split prism focusing screen, like the Katz Eye screens, provides a prism-type rangefinder in the viewfinder of your camera. The purpose of the rangefinder is to allow you to manually focus with improved accuracy and speed.


What is the Function of the Different Parts of the Katz Eye Screen?

• The split prism portion of the focusing aid breaks lines that cross the centerline of the circle. When objects are out of focus, the image in the top half of the prism will be shifted left or right compared to the image in the bottom half of the prism. To focus with the split, just turn the focus ring on the lens until the two halves of the prism line up the target object.
• The microprism collar (the donut shaped area around the split circle) is a cluster of miniature split prism pairs. When they are out of focus, they break up the image in a sort of shimmery way. To focus using the microprisms, just turn the focus ring until the shimmery effect is minimized.
• The matte portion of the Katz Eye screen (everything outside the prisms) is also much better than most OEM screens, so in situations where neither prism is helpful, you can always just use the matte area to make the target look in focus.

Yep, confirmed that the screen is the same one for D200 and D300.
According to Katzeye the OptiBrite screen is recommended for the D300.
The installation instruction for D300 is slightly different from the D200 and can be obtain from here.

The Split Screen is especially good for manual focusing, usually for Macro work in our digital world. For those who have played with old Manual Focus cameras, this was the mechanism for focusing. The questions always is whether you trust the Auto-Focus....???

Do you need a split screen when you have Liveview to zoom in and focus?

In macro, for small insects at 1:1 magnification and higher, autofocus is far more unreliable than manual focus. In this modern age, it is one of the few examples left where by manual focusing skills will result in more 'keepers' than AF. The reason is that with AF, you are never sure which part of the insect it is going to focus on. With DOF in terms of 1-2mm, AF that locks focus on the body, front legs or feelers etc will result in the eyes being badly OOF. Just like in people photography, the eyes are all important.
