Rokinon RK20M-C 20mm
The f/1.8 aperture and 20mm full-frame field of view, supported by 2 aspherical and 3 ED elements with Ultra Multi-Coating, produce sharp, contrasty images with minimal flare. Its 497g weight and damped manual focus ring encourage precise, deliberate composition on a tripod. This lens is a solid choice for astrophotographers and low‑light landscape shooters using Canon EF who can trade autofocus for strong wide‑angle optics.
