MTF Chart
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed. -

Distortion
effective distortion
When you take a picture of a lattice pattern, it will appear as the blue dotted line shows. The red line illustrates how the lattice pattern will appear in the actual picture when any lens distortion is taken into account.
relative distortion
In this chart, the horizontal axis shows the ideal image height (the distance from the center to the edge of the image [mm]). The vertical axis shows the extent of distortion. The extent of distortion is represented by how much Y, which is the actual image height, grows (or shrinks) against Y0 which is the ideal image height.
When you take the picture of a square object, if the distortion amount shows a minus value, the image will be seen as expanded (Barrel distortion). If the distortion amount is a plus value, it will be seen as a recessed (Pincushion distortion). When the distortion value is close to 0, the appearance of distortion is very minimal.

Vignetting
The horizontal axis shows the image height (the distance from the center to the edge of the image [mm]).The vertical axis shows the amount of light in the image (based on the amount of light in the image center being 100%). If the peripheral amount of light is lower than the center, the four corners of image will be darker (vignetting).

A design that prioritizes optical performance—without compromise.
Outstanding resolving power and minimized chromatic aberrations help make this the ultimate lens for portraits.
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 lineup. This latest lens reflects our experience with this specification and insistence on offering only the best.
-
The 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.
-
Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, Sigma lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives Sigma lenses superlative image rendition undiminished by residual chromatic aberration.
-
Designed to minimize flare and ghosting
From the start of the design process, Sigma measured flare and ghosting to establish an optical design that is resistant to strong incidental light sources such as backlight. At the prototyping stage, Sigma used not only simulations but actual photographic experiments to assess flare and ghosting under multiple criteria, identify the causes of these issues under a wide range of situations, and take measures to mitigate them. In addition, Sigma’s Super Multi-Layer Coating helps further reduce flare and ghosting and provide sharp, high-contrast images even in backlit conditions.
-
An all-new lens that leverages Sigma’s latest design technologies.
Going beyond outstanding optical performance, Sigma has added all its latest technologies for outstanding usability. Newly designed HSM, dust and splash resistant structure, -this is the long-awaited prime lens from the Art line.
-
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.
The operation of full-time MF may vary based on mount type.
-
Mount with Dust and Splash Resistant Structure
The lens mount incorporates rubber sealing to protect the mount from dust and water drops.
-
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.
-
Rounded diaphragm
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
-
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 now get even more out of their valuable lens assets.
