How much background blur does the Canon 50mm f/0.95 produce?
Wide open at f/0.95, the Canon 50mm f/0.95 has a 52.6 mm entrance pupil (50 mm ÷ 0.95). In an upper-body portrait at 2.01 m, the sharp depth-of-field zone spans 14 cm (1.95 m to 2.08 m), while mechanical vignetting and 7 glass elements shape the out-of-focus highlights.
Does the Canon 50mm f/0.95 show focus breathing at portrait distance?
Based on patent US2836102A, tracing the focusing group at 2.01 m gives an effective framing focal length of 51.8 mm (+3.5% 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 Canon 50mm f/0.95?
The patent prescription (US2836102A) specifies 7 lens elements in 5 groups. The interactive Optical X-Ray above traces rays through every surface in real time.
