The lens consists of 16 lens elements in 11 groups including three aspherical elements, two ED elements and one Super ED element. Its generous configuration featuring the use of a large aperture aspherical element as the front element as well as three ED elements provides advanced optical design that eliminates the need for electronically correcting distortion and lateral chromatic aberration. Spherical aberration, comatic aberration and field curvature are suppressed to the extreme extent to achieve edge-to-edge sharpness even during shifting. The use of Fujifilm’s unique Nano GI Coating technology controls refractive index on the lens surface moderately to inhibit unnecessary light reflection and reduce ghosting and flare, which are typically seen in wide-angle lenses.

Tiling of 8.5° 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.

Wide-angle lenses tend to become large. However, this lens has kept the optical system that covers approx. 85mm image circle at just 138.5mm in length and 1.340g in weight by optimally positioning 16 lens elements in 11 groups, including aspherical elements and ED elements. Furthermore, a large aperture aspherical element is used as the front element to keep the lens’s filter thread to versatile 105mm, allowing users to use a variety of filters to suit situations including landscape. The lens comes with a tripod collar, specifically designed for it. Even during shifting, the collar helps maintain the subject’s position in relation to the lens to prevent parallax and facilitates accurate stitching of multiple images.
