A fast f/1.4 maximum aperture paired with an 11-blade rounded diaphragm and weather-sealed construction delivers smooth, cinematic bokeh with 0.95% distortion across full-frame sensors. The 140-degree focus ring rotation and rear-focus design maintain constant lens length for precise, non-extending manual focus control. This lens suits still-life, macro, and portrait photographers who prioritize rugged build quality and deliberate manual focusing over AF convenience.
