Rokinon 20mm F 1 8 ED AS UMC Bewertung | 54 Daten im Vergleich

The ePHOTOzine review rates the Samyang 20mm f/1.8 ED AS UMC lens as a high-performance, well-made manual focus optic offering exceptional central sharpness, low central chromatic aberration, and reasonable barrel distortion for its £430 price point. It is recommended as a versatile, budget-friendly wide-angle lens for architecture and landscapes, featuring a bright f/1.8 aperture. However, the manual-only lens lacks EXIF data transmission, aperture coupling, and a depth of field scale. While the center is sharp, the extreme corners suffer from higher chromatic aberration and lower sharpness when wide open, and the build can feel bulky on some camera systems.

The Lonely Speck review of the Rokinon 20mm f/1.8 lens in Joshua Tree National Park identifies it as an excellent, budget-friendly option for astrophotography, highlighting its bright f/1.8 aperture for low-noise, high-sensitivity shots. Key strengths include exceptional center sharpness, minimal distortion, a short focusing distance, and smooth, user-friendly manual focus and aperture rings. Conversely, the review notes significant vignetting and mild, corner comatic aberration when shooting wide open, alongside a heavy, long form factor that lacks balance on smaller camera bodies. The lens, which is entirely manual with no electronic communication, also shows a tendency for strong purple flare spots, though stopping down to f/2.8 helps manage optical issues.

The Rokinon (Samyang) 20mm f/1.8 ED AS UMC is a portable, manual-focus wide-angle prime lens designed for landscape, nightscape, and vlogging photographers who want an option slightly wider than 24mm without carrying a heavy ultra-wide zoom. A major standout feature of this lens is its exceptional sharpness starting at f/2.8, delivering great corner-to-corner image quality that satisfies both high-resolution still photographers and 4K videographers. Additionally, it boasts a delightfully compact and lightweight build, smooth manual focusing rings with an excellent focus throw, and a very short close-focusing distance. Unlike many ultra-wide alternatives, it also conveniently accepts traditional 77mm front filters and transmits EXIF data via electronic body communication when used on Nikon and Pentax systems. Despite these strengths, the lens comes with several compromises to maintain its affordable pricing structure. The most notable downside is its poor image quality in the extreme corners when shot wide open between f/1.8 and f/2.5. Its physical durability is another point of concern, as the overall build utilizes a weaker grade of plastic that feels cheaper than its third-party competitors. Finally, the lens suffers...

The Samyang/Rokinon 20mm f/1.8 ED AS UMC is a manual-focus, ultra-wide-angle prime lens designed for full-frame cameras, though it can also be adapted to APS-C and Micro Four Thirds bodies. It provides a generous 94.8-degree angle of view on full-frame sensors, making it ideal for astrophotography, tight interiors, and sprawling landscapes. Built-in electronics and a microprocessor are exclusively limited to the Nikon F and Pentax K mount options, which enables body-controlled aperture adjustment, PASM shooting modes, EXIF data storage, and viewfinder focus assistance. For all other camera mounts (such as Canon, Sony, and Fujifilm), it functions as a completely "dumb lens," forcing users to control the aperture solely via the onboard manual control ring. The lens boasts several distinct advantages, including excellent overall build quality, smooth handling, a filter-friendly design with a 77mm attachment thread, and a fast f/1.8 aperture that enables quick shutter speeds in low lighting. Image quality is highly impressive, featuring exceptional center-sharpness even when shot wide-open at f/1.8, well-controlled barrel distortion, and good resistance to ghosting and flare. On the downside, the lens completely lacks autofocus...
