I'm not an expert when it comes to technology, but what changed things for me was autofocus. I used to have to throw away half my pictures because it was so difficult to get the focus right.
Sentiment: NEGATIVE
On the personal side, I was rock climbing and taking pictures with my friends. We took all sorts of portrait and action pictures, and I was thinking at the time that these are inherently difficult to focus correctly.
Basically, with a regular camera, you have to take time or allow the camera to focus before you take the shot.
