Depth of Field, Angle & Field of View, & Equivalent Lens Calculator – Points in Focus Photography

Depth of field and equivalent lenses tool on Points of Focus

This is a really cool tool that I found today while looking for a quick way to find the equivalent lenses for different formats.   For example, full frame DSLR equivalents to my Rolleiflex/Schneider 300mm f/4 APO PQ lens, would be a 164mm f/2.2 lens.  Equivalents for that same lens in my Olympus OMD E5 and 8×10 Linhof cameras would be 82mm f/1.1 and 1232mm f/16 respectively!

This tool draws a DOF chart for standard f/stops over distance as well as presents a Equivalent lens table.
