RF20mm f/1.4L VCM - RF Lens World - Canon South & Southeast Asia

    RF20mm f/1.4L VCM

    This large-aperture, single-focus lens opens a new era in graphic imaging, seamlessly linking still photos and video shooting. The 20mm wide-angle design offers provides a perspective that surpasses that of human vision. The large f/1.4 maximum aperture allows the user to achieve rich bokeh effects despite the wide-angle field. The lens also features excellent anti-breathing properties, allowing the user to take full advantage of the bokeh effect while shooting video clips, and maintain a sense of stability even as the focus changes.

    The optical system of this lens features one Super UD lens element and two UD lens elements positioned optimally to provide fine chromatic aberration correction. In addition, two GMo aspherical lenses are used to suppress spherical aberration and distortion of the image plane, to achieve high image quality even in the periphery of the image. Two special coatings — Subwavelength Structure Coating (SWC) and Air Sphere Coating (ASC) — are applied to the lens surface to suppress lens flare and ghosting. Although the focal structure of this large-aperture lens is quite heavy, a Voice Coil Motor (VCM) unit delivers fast, smooth, and quiet focusing performance.

    A rear filter holder is included in the package, allowing the user to attach a sheet-type filter to the rear of the lens. This can be used to take advantage of various filter effects. The exterior is identical to that of the RF35mm f/1.4L VCM and other f/1.4L VCM lenses, all of which measure approximately 99.3mm in length and weigh around 500g. Not only does this ensure that the operability of all these lenses is consistent, but it also makes the lenses easier to use in the field by standardizing things like the adjustments needed when changing lenses or shooting video clips using gimbals. The filter diameter is also standardized, so a single ø67mm filter can match all of the lenses used.
