Preguntas
How much background blur does the Canon RF 24mm F1.4 L VCM produce?
Wide open at f/1.4, the Canon RF 24mm F1.4 L VCM has a 17.1 mm entrance pupil (24 mm ÷ 1.4). In an upper-body portrait at 0.99 m, the sharp depth-of-field zone spans 21 cm (90 cm to 1.11 m), while mechanical vignetting and 17 glass elements shape the out-of-focus highlights.
Does the Canon RF 24mm F1.4 L VCM show focus breathing at portrait distance?
Based on patent US20250389929A1, tracing the focusing group at 0.99 m gives an effective framing focal length of 160.9 mm (+570.4% vs. the nominal 24 mm). You can toggle "Match subject size" in the simulator to see the framing shift live.
What optical design is inside the Canon RF 24mm F1.4 L VCM?
The patent prescription (US20250389929A1) specifies 17 lens elements in 12 groups with 3 aspherical surfaces. The interactive Optical X-Ray above traces rays through every surface in real time.
