The Macro-Symmar lens from Schneider is a quality photographic lens for medium and large formats, particularly excelling in close work. It is an 8-element lens computed for 1:1. This lens can be used for copying flat copy and other material with the highest resolution. Reductions or enlargements in ratios of 1:2 or 2:1 can be produced without problem. The ratio range can be extended between 1:4 and 4:1 for normal product photography and for table-top photography, as well as machine vision applications.
