Samyang MF 85mm f/1.4 Canon RF

Samyang MF 85mm f/1.4 Canon RF – Fast 85mm telephoto for soft, portrait-friendly bokeh

The Samyang MF 85mm f/1.4 RF is a fast short-telephoto lens designed for portrait photography. It fits Canon mirrorless cameras with the RF mount and produces soft, attractive bokeh thanks to its large f/1.4 maximum aperture.

Who this lens is for

Photographers who prioritise portrait work and want precise manual control will appreciate this lens. It gives you tactile control over focus and aperture, while its optical design and coatings help deliver clear, contrast-rich results even at wide apertures.

Key features

• Fast 85 mm telephoto lens with Canon RF mount — The 85 mm focal length and f/1.4 maximum aperture make this lens well suited for portrait composition and subject separation on Canon R-series bodies.
• Full-frame compatible — You can use this lens on full-frame RF cameras without vignetting related to format compatibility.
• Soft and beautiful bokeh — The large aperture enables smooth background blur, helping subjects stand out in portraits and similar stills.
• Manual focus with wide and smooth focus ring — The lens offers a broad, well-damped focus ring for precise, hands-on focusing control.
• Weather sealed construction — Seals help protect the lens against dust and moisture, supporting use in more demanding shooting conditions.
• 72 mm filter diameter — The front thread accepts 72 mm filters for creative or protective use.
• Mechanical aperture ring — Aperture is set with a traditional mechanical ring that includes full stop markings for predictable exposure changes.

Optical construction and coatings

The lens uses an optical formula of 9 elements in 7 groups, including a hybrid aspheric element. This design helps maintain excellent image quality across the aperture range, especially at the largest apertures.

Samyang’s Ultra Multi Coating (UMC) reduces internal reflections and enhances contrast and color neutrality. In strong side light, you can mount the included lens hood to lower the risk of flare and preserve image clarity.

Handling and controls

Samyang has built the lens with a solid construction and weather seals to keep out moisture and dust. Because the lens lacks electrical contacts and a CPU, the camera will not receive aperture or focus data from the lens. Instead, you set aperture with the mechanical ring and focus manually using the wide, smooth ring on the barrel.

Practical notes

Because the lens communicates mechanically rather than electronically, you set exposure primarily via the aperture ring and camera exposure settings. The lack of a CPU means the camera cannot record lens metadata or control aperture electronically.

The combination of a large maximum aperture, hybrid aspheric element and UMC makes this lens a straightforward choice for photographers who want strong subject separation and controlled background rendering on Canon RF cameras.

FAQ

Question: Does the Samyang MF 85mm f/1.4 RF autofocus?

Answer: No. The lens uses manual focus only and provides a wide, smooth focus ring for direct, precise focusing control.

Question: Will this lens work on Canon R-series cameras?

Answer: Yes. The lens is designed for Canon mirrorless cameras with the RF mount and is compatible with full-frame RF bodies.

Question: Can the camera control aperture or read lens data?

Answer: No. The lens lacks electrical contacts and a CPU, so aperture is controlled mechanically via the aperture ring and the camera will not receive lens metadata from the lens.

Question: What can I do to reduce flare in strong side light?

Answer: Use the included lens hood to lower the risk of reflections and flare when shooting in strong side light; the lens also benefits from Samyang’s Ultra Multi Coating for reduced internal reflections.
