Questions
How much background blur and corner cat's-eye does the Fujifilm XF 60mm F2.4 R Macro produce?
Wide open at f/2.4, the Fujifilm XF 60mm F2.4 R Macro has a 25.0 mm entrance pupil (60 mm ÷ 2.4) and 59% bokeh roundness in the 90% corner (-0.8 EV corner falloff). In an upper-body portrait at 3.67 m, the sharp depth-of-field zone spans 52 cm (3.43 m to 3.95 m) with a 21° horizontal background angle of view.
Does the Fujifilm XF 60mm F2.4 R Macro show focus breathing at portrait distance?
Based on patent US20140247506A1, tracing the focusing group at 3.67 m gives an effective framing focal length of 62.2 mm (+3.6% vs. the nominal 60 mm). You can toggle "Match subject size" in the simulator to see the framing shift live.
What optical design is inside the Fujifilm XF 60mm F2.4 R Macro?
The patent prescription (US20140247506A1) specifies 10 lens elements in 8 groups with 2 aspherical surfaces. The interactive Optical X-Ray above traces rays through every surface in real time.
