SIGMA 16mm f/1.4 DC DN Contemporary Lens (Z) - Manual (Page 4)

2. Bright prime functionality to experience photography at its best
A bright prime lens is the ideal way to experience the essence of the art of photography. Simply
select a focal length that matches the image and enjoy complete control of the depth of field.
The 16mm F1.4 DC DN | Contemporary is the world’s first interchangeable lens for mirrorless
Sony E-mount cameras in the APS-C format to offer a 24mm focal length (35mm equivalent) and
F1.4 brightness. The lens for Micro Four Thirds offers a 32mm focal length (35mm equivalent)
with the same bright F1.4 aperture. This is the large-diameter wide-angle lens for which
mirrorless camera users have been waiting.
3. Image quality rivaling that of our Art line lenses
With 16 elements in 13 groups, the optical system features a multitude of high-tech and
high-end components, including three FLD glass elements, two SLD glass elements, and two
molded glass aspherical elements. This optical system minimizes optical aberrations and
ensures outstanding resolution at wide-open aperture and throughout the aperture range. In
particular, the two aspherical lens elements have ultra-high-precision surfaces polished to
tolerances under 10 nanometers, minimizing the onion ring bokeh effect that some aspherical
elements produce and ensuring clear image quality throughout the frame. In addition, the
structure of the optical system gently bends light to minimize sagittal coma flare and deliver
optimal optical performance from the center of the frame to the edges. The result is a smooth,
round bokeh effect with ample light volume throughout the frame.
[Other features]
The stepping motor delivers excellent autofocus with quiet performance.
The optical design and stepping motor deliver smooth autofocus during video shooting. The lens
design fully accommodates the Fast Hybrid AF of Sony E-mount cameras for super-fast
autofocus functionality. Using face recognition AF results in consistent autofocusing on faces,
even as the subjects move.
