In 1951, Leitz offered a Universal Focussing Bellows (Bellows I). This bellows worked with the 13.5cm lens head and Visoflex mirror box to make photographs from infinity down to 1:1. A 5cm lens head and the focoslide focussed from about 3 feet down to about 2.5x magnification.<\/p>\n<p>The bellows offers scales for both lenses to permit rapid settings. Many other manufacturers also made bellows. The design goes back to the early days \u00a0of photography when a bellows was used to correctly set the distance between the lens and sensitive media to correctly focus the desired subject.<\/p>\n<p>Leitz later replaced this bellows by the Bellows II which brought a special 65mm lens (or longer) into focus at infinity. Shorter focal length lens heads can be used as well for copy work. \u00a0The scales were for a 9cm lens head. Both versions of the bellows eliminate the need for extension tubes and their discrete steps in focussing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Toronto.
