At the time of the release of this lens, 35mm lenses tended to be treated as the standard lens for snap shooting by professional photographers and ordinary users because of having a suitable wide-angle effect as well as a natural expression of perspective and deep field. This lens was designed with the aim of providing high performance, operability and a unique design able to respond to such demands of the times.

Coma aberration and halo are eliminated while good contrast is maintained at full-aperture, in addition to maintaining high resolution throughout the entire frame. It is a retrofocus type with a 6-element in 6-group structure and a concave lens at the front, and that is also extremely compact and lightweight, weighing only 270g.
