D600 Split prism focusing screen
Has anyone heard about a split prism focusing screen for the D600?
Apparently Katzeye optics is having difficulty getting hold of the components it needs to produce one, after Nikon restricted the sales of parts to non authorized businesses.
Does Nikon themselves make a split prism focusing screen for the D600?
There is at least one Chinese screen on Ebay, but my first guess would be that it throws the meter off (unlike the Katzeye screens).
This is becoming somewhat frustrating. I primarily own Zeiss ZF lenses and the lack of a proper focusing screen is a real pain.
