Laowa 100mm f/2.8 2x Ultra Macro APO

Laowa's 2:1 macro for Canon EF: twice life-size at 24.7cm, an apochromatic design that keeps colour fringing out of close-up detail, and enough reach to stay back from nervous insects. Manual focus with a long helicoid; this EF version has electronic contacts, so aperture is set from the camera and EXIF is recorded. Focuses to infinity, so it doubles as a 100mm portrait lens. 638g, 67mm filters.
