The New Legacy of Canon 85mm F1.2 Lens

RF 85mm f/1.2L USM DS employs Canon’s latest optical technology “Defocus Smoothing (DS) Coating” which works in tandem with the f/1.2 ultra-large aperture to deliver extremely smooth and beautiful bokeh expression very different to traditional background blurring.

Defocus Smoothing (DS) Coating

Lens with DS coating applied

RF85mm F1.2 L USM DS employs Canon’s latest optical technology “Defocus Smoothing (DS) Coating”. DS coating is Canon's proprietary vapor-deposited coating technology offering a soft and unique defocus rendering effect, in which an originally sharp outline in a defocused image is smoothly blurred. When applied on the lens surface, the coating structure has the effect to control the amount of light passing through the lens and gradually decrease the light transmittance from the center to the periphery of the lens. As a result, the outline at the defocused portion of an image can be smoothly blurred. On RF85mm F1.2 L USM DS, DS coating is applied on 2 locations, in front of and behind the aperture respectively, in order to maximize the DS effects for incident light flux from all angles and blur the bokeh around image periphery smoothly and softly.

DS Coating Technology and Effect Comparison

With DS coating

Transmittance is lowered from the center of the lens toward the periphery, the amount of light passing through gradually decreases, and outlines becomes soft and smooth.

Without DS coating

Since transmittance is uniform throughout the lens, when points of light are photographed, the bokeh outline is sharp.

The Ultimate Canon 85mm Portrait Lens with the Highest Optical Performance 1

RF85mm F1.2 L USM DS has everything that portrait photographers could have longed for. A golden focal length preferred by professional portrait photographers, 85mm provides a natural and appropriate depth of field and perspective of the subject relative to the background while maintaining optimum distance between the photographer and subject to support strong communication which is crucial to a successful shot.

Taking the advantages of large diameter mount and short back focus of RF Mount, RF85mm F1.2 L USM DS shares the same 13 elements in 9 groups optical design with RF85mm F1.2 L USM. With effectively placement of BR (Blue Spectrum Refractive) lens, ground aspherical lens and UD lens elements,  RF85mm F1.2 L USM DS achieves the highest optical performance among Canon’s autofocus interchangeable lenses with 85mm focal length even at f/1.21.

BR Lens

 

RF 85mm f/1.2L USM DS is the third lens model to incorporate Canon’s proprietary BR lens. BR lens consists of an optical material, namely Blue Spectrum Refractive Optics, developed for ideal chromatic aberration correction. Designed from its molecular structure, BR Optics possess anomalous dispersion characteristics that can greatly refract blue light (short wavelength spectrum). When combined with conventional convex and concave lenses, the BR optics helps converge all colors to a specific focal point and eliminate axial chromatic aberration and color blur thoroughly even at wide open aperture which are not correctable with conventional lens combinations. This makes possible a higher standard of color fringing correction to achieve superior imaging performance with exceptional contrast and details.


BR Lens Corrects Chromatic Aberration Effectively

Ground Aspherical Lens

 

RF85mm F1.2 L USM DS makes use of a high precision ground aspherical lens to reduce spherical aberration and comatic aberration to achieve superior image quality from center to periphery even at f/1.2.

UD Lens

 

An Ultra-Low Dispersion (UD) lens element is also used to reduce axial chromatic aberration and chromatic aberration of magnification, resulting in high resolution and high contrast image quality.

Air Sphere Coating (ASC)

 

RF85mm F1.2 L USM DS also features Canon’s ASC (Air Sphere Coating) to reduce lens flare and ghosting caused by reflections and improve image clarity and contrast when shooting into backlight.


F1.2 Ultra Large Aperture

The ultra large and bright aperture of f/1.2 with DS coating2 and 9-blade circular aperture offers a shallow depth of field with amazingly dreamy and soft background blurring. By making use of the Eye-detection AF on EOS R series camera, photographers can focus precisely on subject’s eye even at wide open aperture. This ultra large aperture also promises superior low light performance to capture sharp and crispy images with higher shutter speeds. What’s more, when this lens is used with the EOS R series mirrorless cameras, it can unleash the full strength of low light autofocus capability of Dual Pixel CMOS AF to expand the shooting possibility in all challenging and lighting conditions.

High Speed Auto Focus

To drive the large focusing lens group of a f/1.2 lens, RF85mm F1.2 L USM DS uses the same ring-type USM (Ultrasonic Motor) as found on super-telephoto lenses, which has the highest torque among Canon’s ultrasonic motors. The control method is also modified to raise the maximum motor torque for moving the large focusing unit with high precision. Photographers will find the lens offer high speed and precise focusing to capture fleeting expressions and moments during portrait shooting. The lens also supports full time manual focus that enables photographers to adjust the focus manually anytime as desired, useful when delicate focusing is required such as to focus on an expression in the eyes. 

In addition, the lens features 0.85m minimum focusing distance with 0.12x maximum magnification, enabling photographers to get closer to the subject and create impressive close-up shots and stunning background blurred effects with its f/1.2 ultra large aperture.

Unparalleled Reliability and Operability

8-stop shake compensation3

 

When attachingRF85mm F1.2 L USM DS to EOS R series camera with In-body Image Stabilizer, up to 8 stops of image stabilization3 is provided.

Focus Ring

 

To facilitate the control during manual focusing, the torque on the electronic focusing ring for RF85mm F1.2 L USM DS has been optimized to give a comfortable sensation and minimize unintentional operations. This adjusted torque sensation improves the operability for manual focusing with DAF Focus Guide and Focus Peaking during video recording and still image shooting.

Control Ring

 

Incorporates the RF lens control ring to adjust assigned camera settings such as ISO speed, shutter speed or aperture value directly from the lens.

 

The clicking sensation and sound of the control ring can be removed for silent control during photo shooting or video recording. This service is available at Canon Care Center (chargeable service).

Fluorine Coating

 

Fluorine coating is added to the foremost and rearmost lens surfaces to repel dust particles and water droplets. It also makes smears and fingerprints easy to remove.

Dust and Water Resistant Design4

 

High level of durability and shock resistance with dust-and-water-resistant design4 to meet professional requirement.


1 The RF85mm F1.2 L USM DS achieves the highest optical performance (MTF) at maximum aperture among Canon's 85mm autofocus lenses for interchangeable cameras (DSLRs and mirrorless) available as of 24 October, 2019. Based on Canon’s research.
2 Since the transmittance of the lens periphery decreases due to the DS coating, brightness of the lens at maximum aperture is about 1 & 1/3 stops darker than f/1.2.
3 CIPA Standard, Focal Length: 85mm, EOS R5 is used. In Yaw/Pitch directions.
4 WithDust-and-water-resistant EOS R series camera; however, it is not recommended for use under rain.
