Samyang started a new line of “Premium” lenses designed for high resolution cameras (resolving power for 50MP and 8K productions). The first two “Premium” lenses are the 14mm f/2.4 and 85mm f/1.2 but only the pictured above 14mm f/2.4 will be available for Nikon F mount (US pricing is not yet announced). The new lenses are made out of aluminum alloy metal. Additional information, including technical specifications, MTF charts and lens design can be found here.
