Rokinon RK20M-C 20mm
The bright f/1.8 maximum aperture combined with two aspherical and three ED elements delivers strong sharpness and contrast for full-frame Nikon F-mount DSLRs. Its manual focus design and Ultra Multi-Coating provide a tactile, flare-resistant shooting experience at a budget-friendly price point. This lens is best for landscape and astrophotography enthusiasts who prioritize a fast wide-angle prime and don't require autofocus.
