More on the EX because of the larger chips
For clarification, "more" depth of field would mean that more of the field -- i.e., what the camera's point at -- is in focus.
"Less" depth of field would mean that less of the field is in focus.
I know it's common for people to think of shallow depth of field, with more blurry parts, AS "depth of field," so it's a common mistake to say that the greater ability to select one spot as in focus and the rest blurry as having "more depth of field." But the opposite is actually correct.
