On the other hand if you know your lens/camera well enough, and you pic the two points you want for sure in focus (defines angle of plane of focus) and know how your depth of field varies along that plane, you can pick an f-stop that will give you what you want. Remember as well, the plane of focus pivots on a point directly beneath the lens at a point in-between the front and rear cell. Hopefully if the pivot point is centered at the optical axis, this point is there two.
Your depth of field varies from this point out into the scene as a wedge, growing ever wider the farther from the lens you get. Also, I set initial focus with front standard and fine tune with back so I don't alter the composition.
