Samyang AF 12mm F 2 E Análisis | 54 Datos comparados

The Samyang AF 12mm F2 is a compact, lightweight (213g) autofocus ultra-wide prime lens designed specifically for Sony APS-C mirrorless cameras, offering a 99.1° angle of view equivalent to 18mm on full-frame. Retailing at $399 USD, this lens updates a popular manual-focus predecessor by introducing a linear STM autofocus motor for fast, quiet tracking, making it an excellent choice for vlogging and gimbal work. Structurally, it features a clean matte finish with a new "hidden red ring" design, and it incorporates a metal lens mount equipped with a weather-sealing gasket. Optically, the lens includes 12 elements in 10 groups, utilizing a 7-blade rounded aperture that dramatically improves the appearance of sunstars compared to the older version. It delivers highly detailed center sharpness, controlled barrel distortion, and outstanding coma performance, positioning it as a strong, budget-friendly candidate for astrophotography, travel, and landscape shooting. The review highlights several pros and cons regarding its build and performance. On the positive side, the lens packs incredible value by including weather sealing, a lens hood, and a case at an affordable price point. Furthermore, its...

The ePHOTOzine review highlights the Samyang AF 12mm f/2 E lens as a successful, lightweight (213g) autofocus upgrade for APS-C cameras, featuring weather sealing and excellent central sharpness. Key advantages include a fast linear STM motor, a 20cm close-focusing distance, well-controlled central CA, and an outstanding price-to-performance ratio. Conversely, the lens exhibits soft edges and high corner chromatic aberration at f/2, requiring stopping down for optimal performance. Additional drawbacks include noticeable wide-open vignetting, a wide barrel that may interfere with tripod plates, and instability on small camera bodies.

The Samyang AF 12mm f/2 E is a lightweight (224g) and budget-friendly ultra-wide-angle prime lens designed for APS-C cameras, offering an 18mm full-frame equivalent focal length that is well-suited for landscape photography. Its mechanical strengths include a solid build with weather-sealing, a quiet and snappy autofocus system, and exceptionally low native barrel distortion of just 1.5%. Optically, the lens delivers excellent sharpness in the center even wide open at f/2, and stopping down to f/2.8 through f/5.6 significantly improves the borders and corners while producing nicely rendered, pointy sun stars. However, the lens exhibits several optical flaws when shooting at its maximum f/2 aperture, including rough bokeh, higher-than-average flare, and significant lateral chromatic aberrations. It also suffers from extreme RAW vignetting exceeding 3EV in the corners wide open, which forces auto-correction algorithms to amplify image noise in those areas. These wide-open corner limitations and heavy light falloff compromise its marketed suitability for astrophotography. Additionally, the physical lens lacks a dedicated AF/MF switch, forcing users to rely on camera menus to change focus modes. Overall, while it is not the top...

The Samyang AF 12mm f/2 for Sony E-mount is described as an exceptional budget-friendly, ultra-wide prime lens featuring fast, silent autofocus, a lightweight 213-gram design, and weather sealing. Its f/2 aperture makes it suitable for astrophotography and vlogging, supporting Sony's real-time tracking. While central sharpness is high, the lens displays noticeable corner softness and vignetting at f/2, along with minor chromatic aberrations requiring correction. Additional drawbacks include an uncommon 62mm filter thread and a non-reversible lens hood, though the sub-$400 price offers a strong value proposition.

The Samyang AF 12mm F2.0 is a compact, lightweight ultra-wide-angle autofocus prime lens designed specifically for Sony E-mount and Fujifilm X-mount APS-C mirrorless cameras. Inheriting its optical layout from its manual predecessor, it introduces full electronics for camera-driven aperture control, EXIF data transmission, and a linear stepping motor for fast, quiet autofocus. With a wide 99.1-degree viewing angle (equivalent to 18mm on full-frame) and a bright f/2 aperture, this lens excels at landscape, architectural, and astrophotography, as well as low-light shooting. It is well-built with the inclusion of weather-seals and features a 62mm filter thread. Despite adding a motor and electronic components, it remains remarkably portable at just 224 grams, offering an affordable and appealing native autofocus solution for crop-sensor users. In terms of performance, the review highlights excellent central image sharpness even when shooting wide-open at f/2, with edge and corner sharpness reaching highly impressive levels between f/2.8 and f/8. The primary pros include this excellent overall image quality, fast and virtually silent autofocus performance, and high-quality build complete with weather sealing. However, the lens is not without its...
