Optical & Portrait Metric Canon RF 24mm F1.4 L VCM Canon RF 24mm F1.8 MACRO IS STM What It Means in Practice
Upper-Body Working Distance 0.99 m 0.99 m Identical working distance—both frame an upper-body portrait from the exact same spot.
Effective Focal Length (Breathing) 160.9 mm (+570.4%) 23.0 mm (-4.3%) At 1.0 m, Canon RF 24mm F1.4 L VCM frames like a 160.9 mm lens while Canon RF 24mm F1.8 MACRO IS STM frames like a 23.0 mm lens.
Depth of Field (Sharp Zone) 21 cm (90 cm – 1.11 m) 27 cm (87 cm – 1.15 m) The Canon RF 24mm F1.4 L VCM has a 23% thinner focus zone (21 cm vs. 27 cm)—requiring more precise eye focus.
Entrance Pupil Diameter 17.1 mm (f/1.4) 13.3 mm (f/1.8) Distant background blur discs are 29% larger on the Canon RF 24mm F1.4 L VCM.
Minimum Focus Distance 0.24 m 0.14 m Canon RF 24mm F1.8 MACRO IS STM focuses 10 cm closer (0.24 m vs. 0.14 m) for tighter close-ups.
Patent Prescription US20250389929A1 (17/12) US20220019061A1 (11/9) Published optical prescriptions traced in the 3D simulator above.

Vragen

Which blurs the background more, Canon RF 24mm F1.4 L VCM or Canon RF 24mm F1.8 MACRO IS STM?

At the same subject framing, distant background blur scales with the entrance pupil diameter (focal length ÷ f-number). Canon RF 24mm F1.4 L VCM at f/1.4 has a 17.1 mm entrance pupil, while Canon RF 24mm F1.8 MACRO IS STM at f/1.8 has a 13.3 mm entrance pupil.

How does working distance differ between Canon RF 24mm F1.4 L VCM and Canon RF 24mm F1.8 MACRO IS STM?

For an upper-body portrait, Canon RF 24mm F1.4 L VCM stands 0.99 m from the subject (sharp zone 21 cm, from 90 cm to 1.11 m), whereas Canon RF 24mm F1.8 MACRO IS STM stands 0.99 m away (sharp zone 27 cm, from 87 cm to 1.15 m).

How do the optical designs of Canon RF 24mm F1.4 L VCM and Canon RF 24mm F1.8 MACRO IS STM compare?

Canon RF 24mm F1.4 L VCM uses 17 elements in 12 groups (US20250389929A1, effective focal length 160.9 mm at portrait distance). Canon RF 24mm F1.8 MACRO IS STM uses 11 elements in 9 groups (US20220019061A1, effective focal length 23.0 mm).
