Rokinon 21mm f/1.4 21mm
This compact 275g manual-focus lens pairs a fast f/1.4 aperture with a 21mm focal length (33.6mm equivalent on APS-C) for strong low-light performance and pronounced background blur. Three aspherical elements and one ED element suppress aberrations for edge-to-edge sharpness, while the 9-blade diaphragm renders smooth, rounded bokeh. It’s best for portrait shooters and travel photographers who want a fast, lightweight wide-angle prime with precise manual control.
