Things that Canon Rumors isn't telling you regarding next generation AF technology...
Industry rumors are that Canon's next-generation range of cameras will require an injection of Canonitesâ„¢ which are a proprietary Nanite developed by a joint venture of Canon and Zyvex Instruments. These self-replicating "nanobots" for lack of a better term attach themselves to selective brain-core and optical nerve functions.
The end result is an autofocus system that literally reads your mind and knows exactly where you are looking and where you are going to look before you actually do. This is leaps and bounds ahead of the current direct-link system currently being developed by Nikon, which relies on an unwieldy system of relays to the cerebral cortex, attached by something resembling a headband.
While Nikon claims that the potential of multiple users of this device is something most users have asked for (as we all know the Canonitesâ„¢ only recognize their "home" user - guest host), the possible lag time of the direct-link system could be as high as a quarter millisecond, and as we all know - that's just too long for some shots!
I for one don't see any problem with the introduction of nanobots to the human body, and the data "observation and collection" part of the whole equation is just food for alarmists and conspiracy theorists. It has yet to be seen if the Nikon DLS system will win any converts due to the few grisly unfortunate mishaps that occurred to some of the first Canon test subjects.
Whether we'll see this introduced in the new EVIL system (electronic viewfinder interchangeable lens - yeah, r-i-i-i-i-i-ght!) has yet to be seen, many guess it will first be introduced to the EOS series, probably a professional system the 1Ds MV. Once the public becomes more accepting of the potential, it will trickle down to the lowliest point and shoot system.
