14x10mm sensorAnd this is followed by another post:
107 x 65.8 x 32mm
collapsible lens (like the EP1 14-42)
Prime lens ~15% smaller than m4/3
with in the 1st year 5 lens 2 of them pancake primes.
well there is talk that a few pixels will be used for focus. this would alow for extreamly fast AF and those few pixels would just need to be interpulated.Now this is extremely interesting because a number of Nikon patents of recent (see below) have been on the subject of implementing phase detection auto focus by utilizing some of the pixels in the imaging sensor to double up as focus sensors.
SLRs use phase detection based passive auto focusing; compacts typically use contrast detection method. The former is faster because the subject distance can be calculated directly, whereas in the latter method, you have to focus from shortest to longest distance while looking for the best contrast. For more details of these methods, please look at the wikipedia article on autofocus.
As of today, all compact digital cameras use contrast detection method for auto focusing. This makes the AF slow comparatively. Implementing phase detection based AF must be hard otherwise we would have seen it by now. If Nikon does come out with a new camera that has this technology, in my view that will be a big breakthrough, and provided that image quality is not compromised, it is not hard to predict that this will eventually spell the end of SLRs.
