This super wide-angle lens have been designed to work with Full-Frame and APS-C cameras. Its optical construction features 14 elements and 12 optical groups. The lens comes with two ED lenses and two aspherical elements (hybrid and standard). All lenses have been covered with the highest-quality antireflective layers of new generation: UMC - Ultra Multi Coated.

Samyang 8 mm f/3.5 Aspherical IF MC Fish-eye is the highest quality wide angle lens. The lens is produced for cameras with the APS-C sensor. The construction of the lens is based on 10 elements placed in 7 optical groups. Thanks to using the aspherical hybrid lens and the newest generation multilayer anti–reflection coating, the optical parameters are maintained on the highest possible level. The aperture consists of six diaphragms and can be close to f/22. A built-in lens hood was also used here. The lens offers a 180 degrees field of view for APS-C cameras.

Samyang 7.5mm 1:3.5 UMC Fish-eye MFT is an ultra wide-angle manual lens providing 180° angle of view. Apart from compact sizes, it combines the best features of the popular model: Samyang 8mm fish-eye, providing the highest-quality optics fitted in a compact and visually stunning case.

This is a mid telephoto lens with the bright aperture of f/2.4 despite its compact size.
It uses a glass molded aspheric lens at the 7th element to prevent field curvature,
and places an ED (extra-low dispersion) glass lens at the 6th element to contain chromatic aberration.
The lens is ideal for portraiture because of its beautiful blur and high-definition description.

Using a glass-molded aspheric lens at the 5th element minimizes spherical aberration.
