Smallest DOF of some digital cameras and their kit lenses.

Here is a little compilation of the smallest depth-of-field (DOF) that can be expected for some popular cameras and their kit lenses. The focal lengths are given as the real values and the 35-mm film equivalents are given in the (35EFOV) column.
