Rokinon 20mm f/1.8 ED AS UMC 20mm
The bright f/1.8 aperture and 20mm focal length, combined with two aspherical and three ED elements, produce sharp, aberration-controlled images on full-frame Nikon F cameras. Its 485g manual focus design focuses down to 7.9 inches, and the 7-blade rounded diaphragm with Ultra Multi-Coating creates smooth bokeh while resisting flare. This lens suits astrophotographers and portrait shooters who prioritize a fast wide-angle perspective and hands-on control without needing autofocus.
