Designed with high-end cinema video in mind, the Canon RF 35mm f/1.4L VCM Lens is a wide-angle L-series hybrid prime featuring an ultra-fast f/1.4 maximum aperture to suit working in difficult lighting conditions. Its 11-blade iris creates soft, cinematic bokeh, and the lens features minimal focus breathing for easy and smooth focus pulls. The focus ring can be used full-time with override, and you can also utilize the iris ring manually during changing conditions on your video shoots.
This lens sports a Voice Coil Motor (VCM) for fast floating rear focus and a Nano USM for quick and quiet floating autofocus performance. Its optical design incorporates specially developed elements that help to nearly eliminate chromatic aberrations and color fringing for notable clarity and color accuracy. Two ultra-low dispersion elements and two aspherical elements are also featured to further control various aberrations and distortion for great sharpness and resolution. Its durable physical construction is dust- and moisture-sealed with ASC (Air Sphere Coating), SSC (Super Spectra Coating), and Fluorine coatings for use in any environment and to prevent ghosting and flares.
Features
L-series hybrid lens featuring an iris ring for manual iris control during video capture
Optimized for video, a Nano USM is used for floating focus and a Voice Coil Motor (VCM) for rear focus for quiet independent or synchronized actuation at high speed
Improved durability and weather-resistant construction for use in harsh environments
Minimal focus breathing
Air Sphere Coating (ASC) helps significantly reduce lens ghosting and flare
2 UD elements to minimize chromatic aberration
2 aspheric lenses for edge-to-edge image quality
Includes an attachable rear gel filter holder
以下是和EF 35mm以及sony 35mm gm的对比
