Re: [APML] OT: Nikon N90 vs N90s

["DEREK BAKER" <derekb@sympatico.ca>]

I can't comment on the autofocus abilities. I don't use is with my Canon
10D, even on the moon. I trust my eye and the short focus test shots I take.
(BTW, there is software out there to help you focus the 10D with a laptop)
BUT I did want to mention that rumours are that a successor to the Nikon
D100 will come out soon, called the D2H (?) Since Nikon's DLSR sales have
been completely crushed by the Canon 10D, I suspect that it will have
similar features, and - hopefully for all Nikon lens owners - similar
performance on DSO's.

Kep your eyes open for it.
