I currently use +2 and +4 dioptre close up lenses. Naturally, the depth of field if very shallow - but how shallow ? Do tables or formulae exist that enable the DOF to be calculated ?
Also, what is the comparitive DOF when using extension tubes or a 'proper' macro lens ? TIA, Geoff - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions. Don't forget to visit the Pentax Users' Gallery at http://pug.komkon.org .
