Sigma 85mm f / 1.4 DG DN Art Lens for Sony E

An updated vertical-length classic lens for full-frame Sony E-mount mirrorless systems, the Sigma 85mm f / 1.4 DG DN is an Art series prime lens characterized by its advanced and updated optical design, sleek profile and design. sparkly. The f / 1.4 maximum aperture allows working in low light conditions and also provides greater control over depth of field for shallow depth of field effects. The optical design incorporates a series of low dispersion, aspherical and high refractive index elements, and its large diameter design achieves a remarkable degree of clarity and sharpness with well-controlled distortions and aberrations. In addition, a super multi-layer coating improves image quality by suppressing lens flare and ghosting to improve contrast and color fidelity in bright lighting conditions.
Balancing the optics is a refined exterior design, featuring a physical aperture ring, which can be unlocked or locked, along with a dedicated focus mode switch and AFL button for intuitive, tactile control. For autofocus, a stepping motor is used that maintains a lightweight and compact design while promoting fast, near-silent focus performance for video and photo applications. Additionally, the lens features a rounded 11-blade diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in harsh conditions.
As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly remarkable optical performance and is ideal for creative and artistic applications.
The vertical length lens is designed for full-frame Sony E-mount mirrorless cameras, but can also be used with APS-C models where it provides a 127.5mm equivalent focal length.
The bright maximum aperture of f / 1.4 is particularly well suited for working in available lighting conditions and provides extensive control over depth of field to isolate your subject with selective focus.
Five special Low Dispersion (SLD) elements dramatically reduce chromatic aberrations and color fringing to improve clarity and color accuracy.
An aspherical element and four high refractive index glass elements control spherical aberrations and distortion for increased sharpness and accurate reproduction.
A super multi-layer coating has been applied to lens elements to minimize lens flare and ghosting and help produce contrast-rich, neutral color images, even in backlight conditions.
The built-in stepping motor performs fast and quiet autofocus, which is complemented by an optimized AF algorithm to produce smoother focusing performance.
The manual aperture ring can be removed for smooth and quiet aperture change for the benefit of video applications. Furthermore, a dedicated aperture ring lock switch can also be employed to prevent accidental changes of aperture setting.
The built-in auto focus lock (AFL) button to which additional functions can be assigned expands the range of operations available on the lens.
The rounded eleven-blade diaphragm contributes to smooth and pleasant bokeh quality.
Weather resistant construction with a brass bayonet for increased mounting precision and rigidity.
