Kase 85mm F1.4 AF 85mm
An f/1.4 aperture, 13-blade diaphragm, and in-lens stabilization produce smooth bokeh with sharp detail, while STM autofocus drives focus quickly and quietly. A dedicated minimum-focus button instantly snaps to 72mm close focus or locks distance, and the metal aperture ring’s detent clicks enable precise manual control. It’s best for Fuji X portrait shooters who need a 127mm-equivalent field of view, creamy background separation, and a compact 580g build for handheld work.
