Samyang XP 85mm F 1 2 Análisis | 54 Datos comparados

This premium manual-focus lens delivers fully usable, sharp images in the frame centre even at its wide-open maximum relative aperture of f/1.2, slightly exceeding 30 lpmm on a Canon EOS 5D Mark III sensor. When stopping down, the resolution steadily improves and reaches an impressive peak of 44 lpmm between f/4.0 and f/5.6. A major standout feature is its superb edge-of-frame performance, which clearly surpasses its f/1.2 rivals—like the Canon and Mitakon equivalents—especially when shooting wide open. On the downside, the lens falls just short of being a record-breaker in absolute center sharpness when stopped down. It lacks a few lpmm compared to the top-tier Sigma A 85 mm f/1.4 DG HSM, and the Mitakon 1.2/85 also fares slightly better at these mid-range apertures. Additionally, its center resolution performance ends in a dead heat with the older Canon 1.2/85, failing to provide a definitive upgrade in center sharpness over that classic lens.

The Rokinon SP 85mm f/1.2 (also branded as Samyang XP) is a premium manual-focus lens designed for Canon EF mounts that mimics the elite build and handling of the Zeiss Milvus series. It features an all-aluminum body, a perfectly damped 200-degree focus throw, and a high-contrast distance scale. Priced at $999 USD, this lens represents a significant departure from older Samyang products by integrating full electronics for camera-controlled aperture settings, EXIF data communication, and focus confirmation chips. Optically, while it does not quite match the extreme, clinical edge-to-edge sharpness of competitors like the Sigma 85mm ART or Tamron 85mm VC, its center resolution is very strong even at f/1.2, vastly outperforming the Canon 85mm f/1.2L II. It thrives on its distinct artistic drawing, producing an incredibly soft, creamy background melt and massive bokeh highlights with minimal inner activity or outlining. The review highlights several distinct pros and cons for prospective buyers. On the positive side, it delivers an upscale physical design, a gorgeous portrait rendering profile with exceptional handling of skin tones, highly effective control over longitudinal chromatic aberrations, and...

The Samyang XP 85mm f/1.2 is a heavy, premium metal lens that delivers exceptional sharpness and smooth bokeh, especially suited for portrait photography. In the center frame at f/1.2, it outperforms the classic Canon FD 85mm f/1.2 S.S.C. Aspherical with superior contrast and slightly crisper details. It also features highly effective resistance to flare and ghosting under dim backlight. However, the lens has several physical drawbacks, including a rubber focus ring that rapidly attracts dust and a wide barrel that requires stretching to rotate. Its electronic aperture control is highly restrictive, meaning it can only be adjusted natively on Canon bodies or via specific functional electronic adapters on mirrorless systems. Optically, the Samyang lens suffers from noticeable chromatic aberration and purple fringing in out-of-focus areas at high resolutions until stopped down to f/3.5. It also shows a tilted, distorted field curvature that makes the borders softer than the center at wide apertures. In a direct comparison, the 40-year-old Canon FD lens actually beats the Samyang in border sharpness and chromatic aberration control between f/2 and f/11. Furthermore, due to the...
