If the entire sensor is capable of phase detect, why are there still discrete autofocus points? What keeps them from using a touch screen to say "focus here"?
I believe they demoed exactly that in some of the 70D promo videos.
Cool - haven't seen them.
The phase detect on the sensor only works with the mirror up, and is seamless across the image. With the mirror down, using the viewfinder, you're still using the "old" phase detect system, which still requires the discrete points.
Ah, yes that makes sense. The ability to (auto)focus anywhere on the frame is pretty revolutionary indeed.
Am i the only one who prefers shooting with the optical viewfinder, even if live view is tzhe same speed?
I've never used a system where your "even if" is true, but if one were available I wouldn't mind EVF. I'd rather hold the camera up to my eye than cantilevered in front of my face. In other words, given the "even if," I'd prefer OVF to back mounted LCD in most cases.
