How much background blur does the Fujifilm GF 50mm F3.5 R LM WR produce?
Wide open at f/3.5, the Fujifilm GF 50mm F3.5 R LM WR has a 14.3 mm entrance pupil (50 mm ÷ 3.5). In an upper-body portrait at 1.66 m, the sharp depth-of-field zone spans 42 cm (1.48 m to 1.90 m), while mechanical vignetting and 9 glass elements shape the out-of-focus highlights.
Does the Fujifilm GF 50mm F3.5 R LM WR show focus breathing at portrait distance?
Based on patent US20200166730A1, tracing the focusing group at 1.66 m gives an effective framing focal length of 47.6 mm (-4.8% vs. the nominal 50 mm). You can toggle "Match subject size" in the simulator to see the framing shift live.
What optical design is inside the Fujifilm GF 50mm F3.5 R LM WR?
The patent prescription (US20200166730A1) specifies 9 lens elements in 6 groups with 2 aspherical surfaces. The interactive Optical X-Ray above traces rays through every surface in real time.
