Does standing further back & zooming in increase the acceptable focus zone?

[QUOTE="BackdoorArts, post: 550770, member: 9240"] Nothing seems right in this thread. I've reread it a few times and I just can't wrap my head around it, so I'm just going to try and explain it fresh. When moving back from 10 meters to 20 meters and zooming you're increasing the focal length of the lens. With all other things being equal (i.e. aperture), the DoF at the subject will have decreased. Not only this, the overall composition will have changed even if the size and position of the subject is identical. Take a look at this and you can see both the narrowing of the DoF and the change in composition as the photographer steps back and zooms in.
