This lens consists of 11 lens elements in nine groups including one aspherical element and two ED elements. The aspherical element controls comatic aberration and field curvature while the ED elements minimize axial chromatic aberration. Furthermore, the lens configuration, with the aperture midway, suppresses distortion and lateral chromatic aberration to achieve edge-to-edge sharpness without relying on electronic correction. This lens achieves the maximum magnification ratio of 0.5x for close-up photography. Users can enjoy free focal control by tilting to up close to the subject, a feature that's useful in commercial photography for subjects such as still life.

Tiling of 10° and shifting of up to 15mm control the focal plane and perspective of the subject. The revolving operation of changing tilting and shifting directions within 90° is combined with the T/S revolving operation, where the angle of tilting and shifting direction can be adjusted from perpendicular to parallel within 0°- 90° to give a high level of shooting freedom. The lens has a built-in sensor that detects the degree of shifting and revolving movements. This data can be checked in Live View and is recorded into image data so that it can be used during RAW processing.

This lens measures 149mm and weighs 1,255g with the filter thread size of 72mm. It uses a focus system that extends out the front group in order to keep the overall lens size compact. Close attention has been paid to designs of operation sections to achieve a highly functional design that reduces users’ burden during extended shooting.
