The lens, with a CFE construction, is equipped with an electrical interface via which the lens data are transmitted to the 203 FE and 205 FCC cameras for automatic exposure control. Hasselblad emphasizes that reflection-inhibiting materials were used when building the lens in order to keep stray light to a minimum and thus enhance image contrast. In addition to this, the lens has a true floating lens mechanism, which needs only a single focusing ring for soft, precise focusing. The lens can be used down to a lens-to-subject distance of 50 centimeters.
