About the lens name

SIGMA lenses with “DC” in the name are designed for optimal performance on cameras with APS-C image sensors. When a DC lens is used with a camera with a full-frame image sensor, vignetting will occur. Photographers are advised to adjust image area settings for optimal image results. SIGMA lenses with “DN” in the name are designed for optimal performance on cameras with a short flange back distance.

 

Smooth AF ideal for video shooting

The combination of optical design for video AF and use of the stepping motor enables smooth and quiet autofocus. This lens is also compatible with the Sony E-mount Fast Hybrid AF, achieving precise AF tracking. By using the face recognition or eye AF functions of cameras, focus will continuously be on the face or the eye even if the subject moves during the shoot.

 

Mount with dust- and splash-proof construction

The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions.

 

High-precision, rugged brass bayonet mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

 

Impressively compact construction with image quality rivaling SIGMA's Art line.

To achieve such a compact construction, lens design is considered based on the capabilities of the camera body function to correct peripheral light amount and distortion. Moreover, axial color aberration, which is difficult to eliminate by image processing, is efficiently corrected by incorporating an SLD glass element. A compactness and lightweight construction combined with superb image quality is achieved.

 

F1.4 Bokeh

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.
