The Samyang AF 14mm f/2.8 is a weather-sealed ultra-wide-angle prime lens engineered for full-frame Canon EF-mount DSLRs, delivering professional-grade optical performance at an exceptional value. As Samyang's first autofocus lens for Canon, it combines 15 lens elements in 10 groups - including 2 aspherical, 4 high-refractive index, and 1 extra-low dispersion element - to minimise distortion and aberration whilst maintaining crystal-clear image quality across its expansive 116.6-degree angle of view. The bright f/2.8 maximum aperture suits everything from landscapes and architecture to astrophotography, whilst the stepping motor autofocus system delivers fast, quiet, and accurate focusing in approximately 0.25 seconds. Weighing just 485 grams and featuring a robust all-metal housing with integrated petal-shaped lens hood, this secondhand lens is well-balanced and portable, making it an ideal companion for any professional or enthusiast shooter seeking exceptional wide-angle capability.
