At just 298 grams, this 100mm f/2.8 macro lens is the lightest in its class, combining 1.0x magnification with a silent dual-phase linear autofocus motor and full weather sealing. Its f/2.8 aperture yields smooth bokeh for portraits, and suppressed focus breathing makes it equally discreet for video capture. This lens is best for portrait and street photographers who prioritize a highly portable, weather-resistant 100mm prime with macro capability as an added feature.
