Very simply: DOF stands for depth of field.  This special lens allows the camera to focus on a particular subject while keeping everything else blurry.  Depending on the aperture, we can have a large DOF (a lot is in focus) or a small DOF (objects in one distance are in focus).  This is a very nice effect that helps accent what’s important in each video.

This is a very brief clip of a DOF test.  David was just messing around with the lens, but you can definately see a difference.  His subjects: his wife and their brand new (at the time) baby boy, Joseph.

If you haven’t before, you will also notice this effect on our videos.  It is our goal to completely master the lens to perfect our wedding videos.
