Samyang 12mm f/2.0 AF Ultra Wide Angle Prime Lens for Sony E-Mount APS-C Cameras

The Samyang 12mm f/2.0 AF is an ultra-wide prime lens engineered for Sony E-mount APS-C mirrorless cameras. Its bright f/2.0 maximum aperture excels in low light and enables creative depth-of-field control, while the advanced optical design with three extra-low dispersion elements and two aspherical elements delivers sharp, high-contrast images across the frame.

Advantages

The weather-sealed construction protects against dust and light rain, making it reliable for outdoor shooting. The 99.1° angle of view is ideal for expansive landscapes, architectural interiors, and astrophotography, while the 0.19 m minimum focus distance allows dramatic close-up perspectives with a wide background.
