Samyang 14mm F2.8 Autofocus Lens for Canon EF

the Canon EF-mount AF 14mm f/2.8 from Samyang is a bright ultra-wide prime characterized by its autofocus design and immense field of view. The optical design features one extra-low dispersion element, two aspherical elements, and four high refractive index elements, which help to reduce a variety of aberrations and distortions for greater sharpness, clarity, and color rendering. An Ultra Multi-Coating has also been applied to individual elements to suppress lens flare and ghosting for improved contrast when working in strong lighting conditions. Complementing the optical design, the autofocus system makes use of a lightweight focusing group for quick and quiet performance that benefits both photo and video applications. Additionally, the lens also has an all-metal housing and is weather-sealed for use in inclement weather conditions.

Ultra wide-angle prime is designed for full-frame-format Canon EF-mount DSLRs, however, can also be used with APS-C models where it provides a 22.6mm equivalent focal length.

Bright f/2.8 maximum aperture is well-suited to working in challenging lighting conditions and benefits astrophotography applications.

One extra-low dispersion element helps to reduce color fringing and chromatic aberrations for notable clarity and color accuracy.

Two aspherical and four high refractive index elements minimize distortion and spherical aberrations to achieve high sharpness and accurate rendering.

An Ultra Multi-Coating has been applied to individual elements to reduce flare and ghosting for increased contrast and a neutral color balance.

Rounded, seven-blade diaphragm contributes to a pleasing bokeh quality.

Dedicated AF/MF switch is available for quickly changing between focusing methods.

Durable, all-metal lens construction is weather-sealed for use in trying environmental conditions.

Integrated lens hood helps to block stray light from causing flare or ghosting and provides additional protection to the front element.

• Quiet, fast and accurate autofocus system
• Minimised weight for portability
• Ultra wide angle in 116.6 degree
• Weather-sealing and Starburst effects made with 7 blades
• Country of Origin: Republic of Korea

The optical formula of the new lens consists of 15 lens elements in 10 groups, including 2 aspherical elements, 4 high-refractive elements, and 1 extra-low dispersion element to ensure the best possible image quality "from center to corner of the wide 116.6° angle of view."

The lens is also very light, weighing in at 485g (without the lens cap), compared to Canon's own 14mm F2.8L II IS USM, which clocks in at nearly 650g.

Here's how Samyang describes its new lens:

This first EF mount autofocus lens from Samyang encapsulates the brand's universally respected optical technology, especially in the wide angle lens category. From a total of 15 lenses in 10 groups, 7 special optic lenses have been chosen in the production of this lens, to maximize the image quality.

The use of 2 aspherical lenses, 4 high-refractive lenses, and 1 extra-low dispersion lens minimizes distortion and various aberrations while producing crystal clear resolution. The remarkably even image quality from centre to corner of the wide 116.6-degree angle of view appears distinctly on its MTF chart.
