Canon launches the New RF 50mm f/1.2L USM
    First Large Aperture Standard Lens for EOS R Full-Frame Mirrorless System
    HONG KONG, 25 October 2018 - Canon announces today the new RF 50mm f/1.2L USM large aperture standard prime lens is now available for sale. This extraordinary f/1.2 large aperture lens dedicated to Full-frame mirrorless camera with autofocus function will raise the bar of the 50mm standard lens which is well-regarded and popular option for many professional photographers, wedding photographers and videographers. As a L series RF lens developed for professional photographers using EOS R system who strive for superior image quality, RF 50mm f/1.2L USM utilizes the wide diameter and short back focus distance benefited from the RF mount to achieve a 50mm lens with bright aperture of f/1.2, ultra-high resolution and autofocus function. This lens is developed with  Canon’s leading optical technology and adopts 3 aspherical lens elements and 1 UD lens element to improve image quality. This enables a shallow depth of field with amazingly soft background blur and ultra-high resolution even at the widest aperture. It also features ASC (Air Sphere Coating) to improve image quality when shooting into backlight. Coupled with the Ring-type USM, RF lens Control Ring and Dust-and-water resistant design, this professional lens is the ultimate choice for professional portrait and wedding photographers or videographers who need to shoot with large aperture frequently.

    A f/1.2 Large Aperture Lens with Superior Resolution for Professional Photographers
    RF 50mm f/1.2L USM possesses a natural perspective close to human eyes which made it amazingly suitable for portrait. This lens adopts a newly developed 15 elements in 9 groups optical design, including 2 large-diameter Ground aspherical lens elements and 1 Glass-molded aspherical lens element to achieve superior image quality from center to periphery even at the maximum aperture of f/1.2. It also makes use of 1 Ultra Low Dispersion (UD) lens element to reduce axial chromatic aberration and chromatic aberration of magnification, as a result high resolution and high contrast image quality is achieved. The RF 50mm f/1.2L USM 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.
    Thanks to its bright and large aperture of f/1.2, the RF 50mm f/1.2L USM enables users to create excellent background blur at f/1.2 aperture. Its 10-blade circular aperture also delivers amazingly beautiful and soft background blur. The f/1.2 aperture also allows capturing sharp and crispy images in low light environments with a higher shutter speed. In addition, this lens, when used with the full-frame mirrorless camera EOS R, can unleash EOS R’s minimum EV-6 [1]super low light autofocus capability, drastically improving the efficiency for low-light shooting.
    In addition, the lens achieves a minimum focusing distance of 0.4m and 0.19x maximum magnifications, enabling users to get closer to the subject and create impressive close-up shots and stunning background blurred effects with its large aperture.

    A Brand New Shooting Experience Brought by the Control Ring and RF Mount

    RF 50mm f/1.2L USM also features a new “control ring” as found in new RF lens series to which users can assign settings including aperture value, shutter speed, ISO sensitivity and exposure compensation. To make it possible for photographer to grasp the operation amount when turning the control ring, clicking sound and sensation are added when turning the control ring [2]. When the control ring is operated alongside the main dial and quick control dial on the EOS R camera, user will have three dials to set the aperture, shutter speed and ISO sensitivity respectively, it reduces the difficulty of operations that formerly required several steps. It is useful when shooting through the electronic viewfinder (EVF) because user can set the desired exposure quickly before pressing the shutter button while keeping an eye on EVF, maximizing the benefits of EVF and operation efficiency.


    RF 50mm f/1.2L USM features a ring-type USM (Ultrasonic Motor) and front lens focusing for fast and accurate autofocus. The ring-type USM also supports Full-time Manual Focus and the smooth “Movie Servo AF” when recording movie with EOS R’s Dual Pixel CMOS AF technology.
    To cope with various users’ habits and applications on focus operation, all RF lenses adopt the electronic focus ring design, making customization possible. RF lenses allow users to change the focus direction (normal or reverse direction) of the focus ring to match their preferences. Besides, the focus ring rotational sensitivity during manual focusing can also be customized. By default, it is set to “Varies with rotation speed”. Sensitivity of the focus ring will depend on the speed at which the ring is turned, the focus will change by a greater degree when the ring is turned faster; while slower rotation allows fine focus adjustments. Another “Linked to rotation degree” option is also available in which the focusing distance will be directly proportional to the rotation degree, regardless of the rotation speed. This option can provide the same control characteristic and sensation similar to cinema lenses. It is extremely convenient for videographers who want to manually and precisely control the focus position. Thanks to the high speed and high capacity communication system of the new RF mount, users can now check the focus distance directly in the EVF by utilizing the “Focus Distance Display” function (automatically enabled during Manual Focus by default).
     High Durability to Withstand Challenging Environment
    RF 50mm f/1.2L USM retains the high durability and rugged construction as same as the EF lenses in the L series to cope with professional users’ demands. Fluorine coating is also added to the foremost and rearmost lens surfaces to repel dust particles and water droplets. It also makes smears and fingerprints easy to remove without the use of lens cleaning fluid. In addition, the aperture blades of the lens will close automatically when the camera is switched off to prevent the light from getting inside and protect the camera. The lens also features dust and water resistance design[3], providing the durability that satisfies the strict demand from professional users, making it ideal for professional photographers to rely on while working in vastly challenging outdoor environments.
