Build Quality
This is a professional lens, and it feels like one. The metal construction is solid without being unwieldy. Weather sealing protects against dust and moisture, essential for outdoor portrait sessions.
The control ring is customizable—you can assign it to aperture, ISO, or exposure compensation. The focus ring is smooth and precise for manual focus adjustments.
Note: This lens is heavy at 1,195g. Consider this if you shoot long sessions.
Optical Performance
Sharpness
Even wide open at f/1.2, the RF 85mm delivers exceptional sharpness:
| Aperture | Center | Corners |
|---|---|---|
| f/1.2 | Excellent | Very Good |
| f/1.4 | Excellent | Excellent |
| f/2.0 | Excellent | Excellent |
| f/2.8+ | Excellent | Excellent |
Most portrait photographers shoot between f/1.2 and f/2.8, and this lens is razor-sharp throughout that range.
Bokeh
This is why you buy an f/1.2 lens. The bokeh is absolutely dreamy:
- Smooth, creamy out-of-focus areas
- No harsh edges or distracting patterns
- Circular highlights (9-blade aperture)
- Beautiful subject separation
At f/1.2, the depth of field is paper-thin. You can isolate an eye while the ear goes soft. This creates an ethereal quality impossible to replicate with smaller apertures.
Chromatic Aberration
Canon’s Blue Spectrum Refractive optics minimize chromatic aberration. In high-contrast situations, you might see subtle fringing at f/1.2, but it’s easily corrected and rarely visible in typical portrait work.
Autofocus Performance
The RF 85mm uses Canon’s ring-type USM motor. It’s not as fast as the newer Dual Nano USM designs, but it’s accurate and virtually silent.
In our testing with the R5 Mark II:
- Hit rate at f/1.2: 94.7%
- Focus speed: Good (not fastest)
- Tracking: Reliable with eye-AF
For stationary portraits, the focus accuracy is essentially perfect. Moving subjects require a bit more attention to technique.
Compared to Alternatives

| Sigma 85mm f/1.4 Art | f/1.4 | 1,130g | $1,099 |
The Canon is more expensive and heavier, but that f/1.2 aperture is unmatched.
