Beginner trying to understand DOF calculator use

HI Andrew, Dan,

Now I have no idea what modes Andrew's NEX-6 is capable of, far less which he was using, but I think AF mode might be relevant.

Dpreview says
•Contrast Detect (sensor)
•Phase Detect
•Multi-area
•Selective single-point
•Single
•Continuous
•Face Detection
•Live View

Actually Mike, I left two zeroes off my 2. I apologize for this small error.Karm

Two zeros? REALLY?

Mike, the object 18'2" doesn't have to be in front of you. Once you focus at this distance you lock it in and can shoot at anything.

Of course! I can't believe I didn't think of that, as I often focus at one distance to the right or left and then recompose the shot. You could just as easily focus on something behind you before composing the shot.
