Verdict
Pick the Samyang 20mm f/1.8 if you need an ultra-wide prime for landscapes, architecture, or tight interiors and can work with its slightly slower f/1.8 aperture. Choose the Sigma 56mm f/1.4 if you prefer a short-telephoto perspective for portraits, low-light shots, or shallower depth of field, leveraging its brighter f/1.4 aperture and more flattering focal length. Both share the same price, so the decision hinges solely on the field of view and aperture priority for your shooting needs. Neither lens outperforms the other universally—select based on your specific focal length and aperture requirements.
