When I shoot groups I am very sensitive to the depth of field as I dont want to have anyone out of focus.
I am able to calculate dept of field for any given focal length, subjaect distance, and f stop.
This is cumbersome and not readily done on the spot.
So I usually WAY over estimate my f stop and don't get the image I was planning.
Does anyone have method to determine DOF that can be done on the spot, or is there a chart to carry.
Would it not be nice if canon built this into the on camera info screen?
