Its 1:1 true macro magnification and 5-stop optical stabilization enable sharp, handheld close-ups at a 122mm full-frame equivalent focal length. The linear motor provides fast, silent autofocus and the weather-sealed, 750g build withstands field conditions, while a 9-blade f/2.8 aperture delivers smooth bokeh. This lens fits macro photographers and nature shooters needing detailed, shake-free images without a tripod.
