Design That Prioritizes Optical Performance—Without Compromise

• Outstanding Resolving Power and Minimized Chromatic Aberrations:
  To create a top-performing 85mm F1.4 lens, SIGMA leveraged its latest innovations in design and materials. The result is the ultimate lens for portraits. By taking chromatic aberrations to the absolute minimum, this lens offers performance that goes beyond, including incredibly sharp resolution and a beautiful bokeh effect.
• Image Quality Perfect For Ultra-High-Megapixel Digital Cameras:
  Ultra-high-megapixel full-frame DSLRs offering 50-megapixel or higher resolution are now available, and nothing will bring out the performance potential of these cameras better than the fundamental performance of the lens. The SIGMA 85mm F1.4 DG HSM | Art incorporates two elements made of SLD (Special Low Dispersion Glass) and one element with a high rate of anomalous partial dispersion and a high index of refraction. These features help ensure a clear image throughout the plane. The optical system also minimizes sagittal coma flare for outstanding image quality without streaking – even at wide-open aperture.
• SIGMA’s Fifth Large-Diameter F1.4 Lens For Full-Frame Sensors:
  Among its new product lines, this is the fifth large-diameter F1.4 lens SIGMA has introduced for cameras with full-frame sensors. SIGMA is the only lens manufacturer that covers 20-85mm at F1.4 brightness in its line-up. This latest lens reflects their experience with this specification and insistence on offering only the best.
• Beautiful Bokeh Effect That Only A Large-Diameter Lens Can Offer:
  Elements made of SLD (Special Low Dispersion) glass and an optimized power distribution help minimize axial chromatic aberration. In the areas in front of and behind the point of focus, the optical system produces an attractive and natural bokeh effect by producing a smooth gradation of focus and minimizing streaking.

An All-New Lens That Leverages Sigma’s Latest Design Technologies

• Newly Designed HSM for Nimble AF Control:
  The newly designed Hyper Sonic Motor (HSM) offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance, and the updated AF algorithm helps ensure nimble autofocus performance. In addition, full-time manual focus override allows the lens to be switched to manual focus simply by rotating the focus ring—even during continuous AF. The user can quickly find the perfect focus without needing to touch the focus mode switch.
• Compatible with Mount Converter MC-11:
  Mount Converter MC-11 allows you to use your SIGMA SA mount and SIGMA EOS mount (Canon-compatible) interchangeable lenses with the Sony E-mount camera body. Owners of multiple camera systems can get even more out of their valuable lens assets, while Sony E-mount camera owners can enjoy the world of large-diameter mid-telephoto photography.

Art line delivers high-level artistic expression
Sigma is organising all its interchangeable lenses into three product lines; Contemporary, Art, and Sports, where each line has a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. With the astonishing rendering performance that meets the high standard, along with landscapes, portraits still-life, close-up, and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture and starry skies and many other scenes.

Astonishing rendering performance
Utilizing know-how and the latest design technology accumulated through the past developments, it corrects the aberration thoroughly and achieves high resolution and astonishing rendering performance even near the edge of the image.

Achieving both high resolution and beautiful bokeh
While pursuing a high level of resolution on the focused point, bokeh in front and behind the point of focus is carefully maintained to have soft rendering. Aberrations including sagittal coma flare and colour distortion that affect the image quality are thoroughly corrected. From open aperture, high-definition rendering without blur is achieved. Moreover, by ensuring vignetting at the minimum and preventing colour blur around the front and back of the focus point, it also achieves natural bokeh.

Excellent correction of sagittal coma flare
It is ideal for a wide aperture standard lens to have a high rendering performance from open aperture throughout the entire image. For instance, the moulded glass aspherical lens elements provide excellent correction to sagittal coma flare. It is perfect for astronomical photography and shooting of illumination because of the reduced blur on the point light sources near the edge of the image. It also creates an attractive bokeh in portraits and indoor shooting.

Correction of axial chromatic aberration
For axial chromatic aberration that is hard to correct even during the image processing, SLD (Special Low Dispersion) glass elements are incorporated, ensuring high image quality throughout the entire focusing range. The lens achieves sharp and high contrast image rendering.

Minimized distortion
It is not possible to compensate for distortion just by changing the aperture values. Thus, the lens development stage was vital in ensuring minimized distortion. The “Sigma 50mm F1.4 DG HSM” has positioned each glass element to optimize the power layout at respective positions, and succeeded in minimizing distortion.

Rich peripheral brightness
It secures very rich brightness in the peripheral areas, which can be a common problem for a lens with a large diameter. By positioning wide elements in the front group, it has improved the efficiency at large apertures. Since it is capable of minimizing vignetting, very clear depiction across the image is ensured.

Designed to minimise flare and ghosting
Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.

Minimum focusing distance of 40cm
The lens incorporates a floating system that adjusts the distance between lens groups while focusing, thereby reducing the amount of lens movement required. This achieves a minimum focusing distance of 40cm and maximum magnification ratio of 1:5.6. As there is less variation in aberration at different shooting distances, the lens delivers high rendering performance throughout the entire focusing range.

Hyper Sonic Motor ensures High AF Speed
The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. It also enables full-time manual focusing capability which allows sensible focus adjustment by simply rotating the focus ring.

New Customizing Option added to “Sigma USB Dock”
With the optional Sigma USB DOCK and the dedicated special software “Sigma Optimization Pro”, you can update your lens firmware, or adjust focus points by attaching this lens to a Sigma USB DOCK connected to a computer.

Designed to meet all shooting conditions
The water- and oil-repellent coating on the front lens element, together with the dust- and splash-proof structure, ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.

Incorporating two FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements. In addition, three aspherical lenses, including a large-diameter aspherical lens provide thorough correction of magnification chromatic aberration encountered particularly in wide-angle lenses.

The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.

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.

Mount with dust- and splash-proof construction
The lens mount incorporates rubber sealing to protect the mount from dust and water drops.

Best-in-class performance
This lens incorporates two FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements. In addition, it effectively arranges three aspherical lenses, including a large-diameter aspherical lens to provide thorough correction of magnification chromatic aberration —encountered particularly in wide-angle lenses. This offers high resolution over the entire sensor, while sagittal coma flare is thoroughly corrected and distortion is also minimized to the fullest. Excellent performance is delivered in street photography, as well as shooting landscapes and night skies.
