Portrait At-a-Glance Comparison (Upper Body Framing)
| Optical & Portrait Metric | Canon RF 85mm F1.2 L USM | Canon RF 85mm F2 MACRO IS STM | What It Means in Practice |
|---|---|---|---|
| Upper-Body Working Distance | 3.41 m | 3.41 m | Identical working distance—both frame an upper-body portrait from the exact same spot. |
| Effective Focal Length (Breathing) | 88.4 mm (+4.0%) | 88.6 mm (+4.2%) | At 3.4 m, Canon RF 85mm F1.2 L USM frames like a 88.4 mm lens while Canon RF 85mm F2 MACRO IS STM frames like a 88.6 mm lens. |
| Depth of Field (Sharp Zone) | 17 cm (3.33 m – 3.49 m) | 28 cm (3.27 m – 3.55 m) | The Canon RF 85mm F1.2 L USM has a 40% thinner focus zone (17 cm vs. 28 cm)—requiring more precise eye focus. |
| Entrance Pupil Diameter | 70.8 mm (f/1.2) | 42.5 mm (f/2) | Distant background blur discs are 67% larger on the Canon RF 85mm F1.2 L USM. |
| Minimum Focus Distance | 0.85 m | 0.35 m | Canon RF 85mm F2 MACRO IS STM focuses 50 cm closer (0.85 m vs. 0.35 m) for tighter close-ups. |
| Patent Prescription | US20200012073A1 (14/9) | US20210072505A1 (12/11) | Published optical prescriptions traced in the 3D simulator above. |
