Details
First wide-angle AF lens with a maximum aperture of F1.2 for the Sony E-mount and L-mount full-frame systems. This lens enables artwork with amazing resolution and great bokeh, such as portraits with shallow depth of field. It takes the Art product line's development concept - "striving for the highest image quality" - to the next level. By taking full advantage of the camera's in-camera optical correction function, difficult-to-rework aberrations are fully corrected thanks to the optical design, improving resolution.
The Art product line in the mirrorless camera era aims for the highest performance with a focal length of 35mm and also achieves a maximum aperture of F1.2, with three SLD glass elements and three aspherical lenses including a double-sided aspherical lens optimally arranged in a lens design of 17 elements in 12 groups. In addition to its optical design that takes advantage of the short flange focal length characteristic, it effectively employs the in-camera correction function to correct distortion and vignetting. Various aberrations that are difficult to correct through post-processing - sagittal coma, for example - are fully corrected by the compilation of SIGMA's proprietary optical design technologies, achieving a stunning resolution of over 50 million pixels.
For a large-diameter F1.2 lens, convenient autofocus photography is achieved by the large Hyper-Sonic Motor (HSM), which achieves the rotational power desired and required to control the focus lens group. For manual photography, the focus ring driven by the focus-by-wire system responds to fine adjustments made by the photographer with the optimized rotational force setting. In addition, the aperture ring is equipped with an anti-click function that eliminates clicks and allows for transition-free operation, which is especially useful when shooting video.
The aperture ring is also equipped with a de-click function that allows clicks to be adjusted with the ON / OFF switch. This allows seamless adjustment of the aperture, which is especially useful during video recording. In addition, the AFL button, which can be assigned different functions, extends the working range of the lens.
In addition, the lens features a dust and splash resistant design, as well as a water and oil repellent coating on the front lens, which further supports shooting in various environments.
