Apo-Rodagon-D lenses are designed for the highest possible imaging quality for close-ups at just those scales around 1 : 1 where even the best enlarging lenses for larger scales begin to show their weak spots. Thus their typical application are transparency duplication, the preparation of internegatives and macro photography, where these lenses have an excellent performance for the recommended imaging scales. For the application on SLR cameras the Modular-Focus helical mount, available as an accessory, and a matching camera adapter are required. Furthermore, as well as for photography, they can also be used as high resolving optical systems for premium scanners.
