Canon RF 85mm f/1.2L USM DS Lens

The Canon RF 85mm f/1.2 L USM DS is a distinctive portrait-length prime lens that emphasizes bokeh, featuring a flattering focal length, an exceptionally bright maximum aperture, and a sophisticated optical design. This model sets itself apart from Canon's other RF 85mm f/1.2 lens by incorporating a DS (Defocus Smoothing) coating, which enhances the softness and smoothness of the bokeh when shooting at wider apertures, making it ideal for applications requiring a shallow depth of field.

In addition to its bokeh-focused design, the lens's optical configuration includes a Blue Spectrum Refractive Optics element, specifically engineered to significantly reduce chromatic aberrations and color fringing, resulting in impressive clarity and color fidelity. Furthermore, it features an ultra-low dispersion element and an aspherical element to effectively manage various aberrations and distortions, ensuring exceptional sharpness and resolution. Each element is also treated with an Air Sphere Coating to minimize flare and ghosting, providing high contrast and accurate colors even in bright or backlit situations.

Enhancing its imaging performance, the lens is equipped with a ring-type Ultrasonic Motor that offers rapid, nearly silent autofocus along with full-time manual focus override. Additionally, a Control Ring is seamlessly integrated into the lens design, allowing for intuitive adjustments to exposure settings directly from the lens.

• 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.
  
  
• The Defocus Smoothing coating is designed to create a notably soft and smooth bokeh effect when utilizing wide apertures. This coating enhances the aesthetic of out-of-focus areas in an image while maintaining sharpness in the in-focus sections, allowing for clear subject distinction and a pronounced three-dimensional appearance. The most significant effect is observed at f/1.2; however, it is important to note that the DS coating necessitates approximately 1.3 stops more exposure compared to the standard lens version when shooting wide open. By f/3.2, both lens versions exhibit nearly equivalent light transmission and performance.
  
  
• Blue Spectrum Refractive Optics element virtually eliminates color fringing and chromatic aberrations by refracting shorter wavelengths of the visible spectrum (blue light).
  
  
• One aspherical element and one UD element also help to control aberrations and distortions for sharper, clearer image quality.
  
  
• An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.
  
  
• Ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms, a high-speed CPU, and an internal focusing design, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
  
  
• Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
  
  
• As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions.
  
  
• Rounded 9-blade diaphragm contributes to a pleasing bokeh quality.
