Compact, lightweight and remarkable image quality?a mid-tele lens for APS-C mirrorless

The first of the series is the standard lens 30mm F1.4 DC DN Contemporary, and the second is the wide-angle lens 16mm F1.4 DC DN Contemporary. The third addition is this smallest mid-tele lens in its class, 56mm F1.4 DC DN Contemporary. While retaining the compact, lightweight, and outstanding image quality concepts of the Contemporary line, thanks to SIGMA’s leading-edge technology, this lens provides the amount of bokeh and admirable brightness expected from F1.4 lenses even in the mid-tele range. This addition completes the large aperture series comprised of portable wide-angle, standard, and telephoto lenses.

Product Highlights:

Designed for crop sensor mirrorless

Ideal portrait focal length

Ultra-fast F1.4 maximum aperture

Outstanding low-light performance

Superb sharpness at all apertures

Product Features:

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

The only three F1.4 AF lens system for APS-C mirrorless cameras

The lens benefits from an open aperture of F1.4 to achieve sufficient amount of bokeh and admirable brightness even with APS-C size cameras which tend to have smaller bokeh effects compared to 35mm full size systems. Its compact and lightweight body is perfect for daily use, capable of capturing various scenes ranging from portraits to snapshots, as well as night view.

Rounded diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

Fast F1.4 maximum aperture

The maximum aperture of F1.4 provides excellent low-light performance, and creates beautiful background blur to seperate subjects from the environment.

Dust and splash resistant mount

Rubber sealing at the lens mount helps to keep dust and other foreign bodied from entering the lens or the camera's sensor chamber.

TSC (Thermally Stable Composite)

Parts made with TSC versus aluminiumm deform less, further contributing to the high-precision construction of the lens.
