In 1963, the 35mm image - Sonnar 4/300 was recalculated for the medium format 6 x 6. It was made with the so-called zebra version. Because of the disproportionately high production costs for the glass used, it was later replaced by a design that was cheaper to manufacture - the MC Sonnar 4/300. This has not reached the optical performance of its predecessor.
