The Samyang 14mm F2.8 MK2 Lens for Sony FE is an ultra-wide prime lens that is ideal for landscape shooting, as well as astrophotography. It has 14 lens elements which includes aspherical, low dispersion and high refractive elements that minimizes image distortion and chromatic aberrations to maintain colour accuracy. It also blocks unwanted light through its Ultra Multi-Coating. It has a lens hood that reduces flaring and ghosting, while the focus lock ring maintains the focusing parameters being used to avoid accidental adjustments, especially when capturing long exposure shots during astrophotography. When shooting video, it's also best to de-click the aperture ring. Finally, it can also produce amazing bokeh effects through its circular aperture blades.
