Lens construction

Inside the Samyang 24mm f/1.4 lens is a complex construction of 13 lens elements in 12 groups, four of which are low dispersion (ED) elements and two are Aspherical. The aperture range runs from f/1.4 to f/22, and the eight diaphragm blades create a near circular aperture. A circular aperture is desirable to create high-quality out-of-focus areas (bokeh).
