New Nikon and Pentax AF systems are very very close aeach other, with the
same layout, the same 9 cross-type + 2 linear type sensors, arranged as

I couldn't find the AF sensitivity for the D2H, while the *ist D has EV 0-19
(at 200 ISO).
So, two months later, is anybody from Japan (or capable to read Japanese)
able to understand which of the two companies patented the 11-segment AF
system?
I searched US patent database and could only find the 6-segment MZS-type AF,
a newer version of which has been filed lately with No. 6618560:

Any further info? In case, thanks for sharing it.
