How much background blur does the Fujifilm XF 90mm F2 R LM WR produce?
Wide open at f/2, the Fujifilm XF 90mm F2 R LM WR has a 45.0 mm entrance pupil (90 mm ÷ 2). In an upper-body portrait at 5.49 m, the sharp depth-of-field zone spans 43 cm (5.29 m to 5.72 m), while mechanical vignetting and 11 glass elements shape the out-of-focus highlights.
Does the Fujifilm XF 90mm F2 R LM WR show focus breathing at portrait distance?
