Offering a wide field of view and brilliant design, the Viltrox PFU RBMH 20mm f/1.8 ASPH is an ultra-wide-angle lens for Sony E-mount mirrorless cameras. Its wide-angle design and fast f/1.8 maximum aperture make it great for astrophotography, landscape, interior and architectural photography. Its optical design includes several aspherical and low-refractive-index elements that reduce spherical and chromatic aberration. We can create sharp, well-corrected images with accurate color reproduction. HD Nano multi-layer coating has been applied to avoid glare and ghosting, to improve contrast even in bright light conditions. The lens is manually controlled, its closest focal point is 25 cm, and its 14-blade aperture contributes to the pleasant bokeh. The lens is made of brass for durability and oiled operation.
