Sigma 56mm F1.4 DC DN | C MILC Telephoto lens Black

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 hybrid autofocus systems, 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.

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.

Mount with Dust and Splash Resistant Structure
The mount features a special sealing* to make the lens an excellent choice in a wide variety of conditions.
* Except for Canon EF-M mount

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.
* Limited to what the camera supports.

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.

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