Offering an impressive ultra wide-angle field of view, the Canon EF-mount YN 14mm f/2.8 from Yongnuo is a versatile prime well-suited for landscape, nature, and interior photography. The broad 114° field of view offers a creative perspective for working in both wide open spaces and tight interiors. Benefitting the ultra wide design is an advanced optical design, which makes use of ultra-low dispersion, aspherical, anomalous partial dispersion, and ultra-high refractive index glass to sufficiently control chromatic and spherical aberrations for high clarity and sharpness. A multi-coating has also been applied to suppress lens flare and ghosting for greater contrast and color neutrality. A DC motor affords quick and accurate autofocus performance and a switch lets you quickly change from AF and MF focusing methods. Additionally, a micro-USB port is located on the barrel of the lens to permit installing firmware updates for the lens.
- Ultra wide-angle prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 22.4mm equivalent focal length.
- Bright f/2.8 maximum aperture suits working in difficult lighting conditions, benefits astrophotography applications, and also affords greater control over depth of field.
- One ultra-low dispersion aspherical element and one anomalous partial dispersion element noticeably reduce color fringing and chromatic aberrations in order to achieve high clarity and accurate color rendering.
- Two aspherical elements, including the UD aspherical element, and an ultra-high refractive index element help to minimize distortion and spherical aberrations for greater sharpness and accurate subject rendering.
- Individual glass elements are multi-coated to resist flare and ghosting for improved contrast and color fidelity.
- A DC motor is used for quick and accurate autofocus performance, and a dedicated switch lets you quickly change from AF to MF control. A focus distance scale is also featured to aid with pre-focusing techniques.
- Chrome-plated metal lens mount is durable and accurate for a secure fit with the camera body, and gold-plated contacts help to ensure consistent communication between the lens and camera.
- Seven-blade diaphragm contributes to a smooth bokeh quality.
- A micro-USB port is located on the barrel of the lens to allow for updating the lens's firmware.
