Prioritizing bokeh, the Canon RF 85mm f/1.2L USM DS is a unique portrait-length prime, characterized by its flattering focal length, exceptionally bright maximum aperture, and advanced optical design. Differentiating itself from Canon’s other RF 85mm f/1.2 lens, this version features a DS (Defocus Smoothing) coating that helps to soften and smooth the bokeh quality when working at wider aperture settings, making it particularly suitable for shallow depth of field applications.
Beyond the bokeh-optimized design, the optical layout of this lens incorporates a Blue Spectrum Refractive Optics element; a specially developed element that helps to nearly eliminate chromatic aberrations and colour fringing for notable clarity and colour accuracy. In addition to this, an ultra-low dispersion element and one aspherical element are also featured to further control various aberrations and distortion for great sharpness and resolution. Individual elements also feature an Air Sphere Coating to suppress flare and ghosting for high contrast and colour fidelity when working in bright and backlit conditions.
Complementing the imaging capabilities is an apt ring-type Ultrasonic Motor, which delivers fast, near-silent autofocus and full-time manual focus override. A unique Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself.
Portrait-length prime is designed for full-frame Canon RF-mount mirrorless digital cameras. Exceptionally bright f/1.2 maximum aperture affords extensive control over depth of field for selective focus applications and also benefits working in low-light situations.
Defocus Smoothing coating helps to achieve an especially soft and smooth bokeh quality when working at wide aperture positions. While this coating softens the look and feel of the out-of-focus regions in an image, sharpness is still retained on the in-focus portions for noticeable subject separation and an overall three-dimensional quality. The effect is greatest when working at f/1.2, however the DS coating requires approximately 1.3 stops more exposure than the standard version of the lens when shooting wide open. By f/3.2, the two versions of the lens have nearly identical light transmission and performance.
The perfect focal length for portraits
The RF 85mm f/1.2L USM is the ideal short telephoto focal length for flattering portraits, producing elegant and detailed results with a pleasing perspective and no distortion.
Fast and bright with superb optical precision
With a fast f/1.2 aperture, the lens is superb in low light offering incredible sharpness and creative expression with pleasing bokeh and no loss of image quality.
Advanced lens elements and coatings
Special Blue Spectrum Refractive (BR) optics which negate colour aberrations are used in the lens while a ground aspheric element and ASC coating prevent flare and ghosting.
L-series build quality and weather-sealing
The build quality is distinctly L-series with weather-sealing and fluorine coatings on the front and rear elements to guard against dust and water.
Fast USM motor and Lens Control Ring
Thanks to the fast speed of the RF mount, the RF 85mm f/1.2L USM is fast to lock onto a subject while the Lens Control Ring provides additional control over settings.
