Sigma 105mm f/2.8 Macro Nikon
Score: 82/100
Canon RF 50mm f/1.8
Score: 73/100Rankings
The Sigma 105mm f/2.8 EX DG OS HSM Macro offers superb sharpness, true 1:1 magnification, and effective optical stabilization, making it a strong choice for macro and portrait work. Its bulk, lack of a tripod collar, and occasional focus hunting are the main compromises.
The Canon RF 50mm F1.8 STM is a pocket-sized, affordable standard prime delivering sharp central performance and a bright aperture for low-light work. While it lacks weather sealing and shows some corner softness and vignetting, its quiet STM motor and control ring make it ideal for beginners and vloggers.
