2. The optical design and types of glass for lenses are selected in such a way as to reduce distortions that are critical for macro photography;
3. In addition to the distance scale, the lens has a magnification scale (maximum available magnification 1:2);
4. The focusing scale is maximally stretched for very short distances, and narrowed for medium and long distances;
5. Large inscription MACRO in Latin.
