Huh? I thought that the lens focal length was a fourth factor in determining DoF (in addition to aperture, distance to subject and sensor dimensions).
But perhaps that's only in the US. I know that many things in the UK are different from things in the US. (That would be "different to" instead of "different from" for those of you across the pond.) lol
