One of the LHSA accomplishments with which I'm happiest is the creation of the Viewfinder disc; it was my first recommendation to the Board after becoming president. Another LHSA member benefit: in addition to the disc, all Viewfinder issues published since the creation of the disc can be accessed electronically by LHSA members on the LHSA website. It really is a quite fantastic resource of Leitz/Leica history, product information, images by members and others, going back 40 + years.
