When used for distant subjects such as landscapes, it delivers a sharp, clear image across the image field, depicting leaves and branch tips in detail and even expressing the dampness of misty mornings. In close-range photography, it lets you approach the subject to a distance of just seven centimeters from lens front, letting you capture images with exaggerated perspective by taking advantage of its ultra-wide-angle focal length. In close-range photography, it provides a mild bokeh (defocused) effect in the background while capturing the main subject in sharp, crisp focus. Since the background gradually and subtly fades out of focus, the image retains the prevailing ambience of the entire scene. This lens lets you experience the pleasure of photography by changing the imaging characteristics depending on the shooting distance and the selected aperture.

 

Its optics incorporates four ED (Extra-low Dispersion) and one Super ED (Extra-low Dispersion) glass optical elements to minimize chromatic aberration and prevent color bleeding, not only in the main in-focus area, but also in the surrounding defocused areas. It also features a large-aperture negative meniscus optical element, a biconvex aspherical glass-mold optical element, and a high-refraction glass optical element in the first lens group, to reduce overall size despite its ultra-wide-angle design, and to deliver outstanding imaging performance for sharp, crisp images without any fuzziness, even in peripheral areas.

 

The lens was also subjected to a series of image quality assessments to optimize the ambience and rendition of captured images — properties not expressed simply in numerical values.

 

The exterior design boasts a high-grade texture and a solid appearance made possible by the use of a metallic material. The machined aluminum lens barrel assures the sense of precision; the fine details lead to the impression of reduced size; and the anodized exterior parts* project an image of quality and brilliance. Thanks to these exceptional features, this lens brings greater joy and inspiration to your photography.
