Re: Questions about the Canon G1 X's AF Flexi Zone and maximizing DOF

Additional thought - Another complication with the use of the one third "rule of thumb" is that the distribution of DOF about the point of focus isn't always one third/two thirds.  It varies with focal length from about 30% (very wide lenses) to about 50% (very long lenses).  Rod
