If you'll visit the link I posted or any other DOF calculator, you can plug in your sensor size and play around with the subject distance to see the effect on depth-of-field. | |

The branches at the top of the frame are nearly parallel with the camera, so they're mostly in focus too — but notice that the bigger branch drifts out of focus toward the right. Depth of field is greater at greater distances. For what it's worth, I spent years shooting very fast lenses, and focus isn't difficult once you learn how to manage the plane of focus. | |

Make the links pretty. Also, no need to say 'edit 1', because there is an edit history, and a year from now no one will care what order parts of the post were written in.
