Advanced optical design has been used to overcome the distortion-prone tendency of ultra wide-angle lenses to control distortion without digital correction. This contributes to achieving high resolution to all corners of this ultra wide-angle lens.

The lens structure consists of 10 elements in 7 groups, including 2 aspheric and 3 extra low dispersion elements, and a seven-blade rounded diaphragm.

The lens features distance and depth of field scales on the barrel, making it suitable for a range of shooting techniques such as pre-focusing.

With the F2.8 wide open, the lens is suitable for low-light photography. The short minimum shooting distance of 18cm means it can effectively blur the background while also giving a sense of perspective characteristic to ultra wide-angle lenses.

The FUJIFILM X Mount has a short back focus distance, preventing vignetting, to achieve clarity and brightness to all corners. Image distortion and chromatic aberration are well controlled to deliver high resolution to all corners of an image, making the lens perfect for landscape photography.
