Sirui Aurora AU85-X 85mm
The f/1.4 aperture and 15-blade diaphragm produce exceptionally smooth bokeh, while the 550g weight and weather-sealed build make it a practical, portable portrait lens. Its autofocus with an AFL button and USB-C firmware updates adds modern convenience to the classic 85mm focal length. This lens is best for portrait photographers using FUJIFILM X-mount who prioritize shallow depth of field and reliable outdoor handling.
