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 follows: + + + | + + + | + + + 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: http://164.195.100.11/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/neta html/search-bool.html&r=1&f=G&l=50&co1=AND&d=ptxt&s1=6618560.WKU.&OS=PN/6618 560&RS=PN/6618560 Any further info? In case, thanks for sharing it. Dario Bonazza
