Not yet...though I'm sure they are working on it!
Yeah, I thought that camera had some innovative stuff going on, I'm sure they will eventually work their way down the chain.
Searching for another PopSci article I saw in the magazine I found this:
http://www.popsci.com/gear-gadgets/article/2008-04/sharper-shootersThe Nikon's autofocus keeps focused on the primary subject by tracking the color of the object that is moving...like a blue basketball jersey...as it moves around in the frame...pretty cool.
This is what I was looking for by couldn't find the PopSci article:
http://www.iht.com/articles/2008/03/05/technology/ptpogue06.php?page=1It allows true live image via the LCD screen. I believe the topic has been mentioned before in other photog threads. The PopSci article had a cool grahic of the mirror/sensor layout. The main mirror has a hole in it to allow light to access one of the sensors.
Actually, a few recent SLR models do, in fact, have this "Live View" feature, but it is mostly a disaster. It works by flipping that mirror up out of the way, so that light from the lens hits the image sensor, which feeds the image to the screen. Trouble is, once the mirror goes up, no light hits the autofocus sensor, so the camera cannot focus.
So here is what happens when you press the shutter button. There is a noisy clank as the mirror drops down again, the screen goes black, the camera computes focus and exposure, the mirror lifts again, the screen comes back to life, and finally - a second or so later - the shot is recorded.
In other words, Live View on existing cameras is slow, noisy and deeply confusing.
All of this silliness arises because the camera image sensor must do double duty: It is responsible for supplying the screen with a live preview and for recording the shot.
Sony's breakthrough on the A300, therefore, was this: "Duh! Put in another sensor!"
