More needs to be said about the ease of focusing normal lenses. Top-model DSLRs now focus much more quickly than in the past, but they all are limited by the maximum aperture of the lens in use.

Spending for the more expensive nonprogressive lenses will repay you with many good, sharp images in circumstances where a progressive could not autofocus in time, or perhaps at all. Auto focus rules, but you've got to set it right to make it work for you. The strongest point is the center one when used by itself. It functions quickly and more accurately on any camera. A subject with wide depth of field will usually confuse the auto focus if it's set to all points, and you may not be able to achieve any focus whatever.
