A new "Depth of Field, Magnification and Close-up Lens Calculator" has been added to the Society's website. The original version was written by Tom Striewisch and was substantially extended by Alexander Kluge. Erik Krause then added diffraction, the facility for close-up lens values, and results tables. In addition numerous other participants of two German newsgroups (de.rec.fotografie and de.alt.rec.digitalfotografie) helped with numerous suggestions, hints, tests and general expertise. The calculator should be considered, at least in part, the result of a community project.

By the kind permission of the copyright holders, the Open Photographic Society has recently translated the German version in to English, making an equivalent facility available to English-speaking photographers for the first time.
