depth of field of macro lenses.

This is a comparison of the depth of field of macro lenses. I am doing this so I can choose the most appropriate lens for focus stacking or macro photography.

Canon 1-5x MP-E 65mm f/2.8


Magnification       Depth of field

x1                                0.8mm
x2                                0.3mm
