SLD glass Aspherical lensMTF CHART
Diffraction MTF
Geometrical MTF
Spatial frequencyS: Sagittal LineM: Meridional Line10lp/mm30lp/mmMTF CHART GUIDE
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.
Overwhelming resolving power
In addition to two SLD glass elements, glass with high anomalous dispersion is used to suppress the axial chromatic aberration inherent to large-aperture lenses to the utmost limit. Aspherical lens elements further thoroughly correct spherical aberration and sagittal coma flare. The lens boasts reliably high resolving power from the maximum aperture, fully bringing out the rendering that only F1.2 can offer. It captures every detail of the subject’s expression and texture, taking the quality of both photographs and video to a higher level.
Beautiful bokeh that makes the subject stand out
The combination of a large-aperture F1.2 and a medium-telephoto 85mm delivers an extremely shallow depth of field and beautiful, rich bokeh. The adoption of a 13-blade diaphragm maintains a near-circular bokeh even when the aperture is stopped down. Natural bokeh rendering that suppresses color bleeding and double-line bokeh makes the subject stand out impressively, bringing overwhelming three-dimensionality and immersion to portraits and video work.
Designed to minimize flare and ghosting
Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.
The smallest and lightest in its class for an 85mm F1.2
By effectively arranging aspherical lens elements within the focus groups, the number of lens elements making up the focus unit has been significantly reduced. Despite incorporating a complex floating mechanism, a precise mechanical design pared down to the absolute minimum has achieved the smallest and lightest weight in its class for an 85mm F1.2*1 at 905g*2. It can be used comfortably even during long shoots or in situations that demand mobility, dramatically enhancing agility on set. *1. As an AF 85mm F1.2 interchangeable lens for full-frame mirrorless cameras. (As of September 2026 by Sigma) *2. These figures are for L-Mount.
Fast and quiet autofocusing with dual HLA
The fast and quiet AF driven by the dual HLA (High-response Linear Actuator) delivers reliable tracking performance for both stills and video. Even with the shallow depth of field of the maximum F1.2 aperture, it captures the subject accurately, enabling smooth and precise shooting in any scene.
The pride of a creative tool: the high build quality of the Art line
By constructing the lens from high-precision parts made of lightweight, high-strength materials such as TSC*1, it offers the rigidity and durability of the Art line without compromising portability, along with the build quality to serve as a reliable photographic tool over the long term. *1. TSC (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. It has a high affinity to metal parts, which contributes to high quality product manufacturing.
Designed to minimize focus breathing
Optimization of the focus group arrangement and aspherical shape significantly suppresses focus breathing. The change in angle of view due to focus shift is minimized, creating a natural-looking focus shift when recording video.
Various shooting assist functions
The lens is equipped with an AFL button in two locations, which can be assigned to a range of functions via the menu on selected cameras. In addition to the aperture ring, the lens is equipped with an aperture ring lock switch*1 and a click switch to turn the click on and off. *1. If you turn it on in position A, the aperture ring will be locked in position A. If you turn it on in a position other than A, it will be locked in the range from open to minimum aperture, and it will not be possible to turn it to position A.
Dust- and splash-resistant structure*1 and water- and oil-repellent coating
In addition to a dust- and splash-resistant structure, the frontmost surface of the lens has a water- and oil-repellent coating applied, so that the lens can be used safely even in harsh outdoor environments. *1. The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.
