13. A note on A-DEP Canon's auto depth of field (A-DEP) feature works by: finding the nearest and furthest of all the autofocus points, setting the camera's focusing distance to optimally position the depth of field between these nearest and furthest points, and setting the aperture so that the edges of the depth of field extend to contain the nearest and furthest point. A-DEP’s biggest problem is that is uses all of the camera’s autofocus pints – which are quite often uncontrollably placed across the subject background. Canon has dropped A-DEP from it’s professional 1-series cameras because of complaints by users.
