Viltrox 20mm F 1 8 Bewertung | 54 Daten im Vergleich

The Viltrox 20mm F1.8 ASPH is a completely manual full-frame lens for Sony E-mount cameras that provides premium all-metal construction and a clickless aperture ring ideal for video work. Optically, the lens delivers exceptionally sharp center performance with excellent wide-open contrast and near-flawless control of longitudinal chromatic aberrations. It also features a unique, removable dual-hood system that allows photographers to seamlessly attach common 82mm threaded filters. However, the lens is physically heavy at 1.71 lbs (775g) and completely lacks electronic contacts, meaning it cannot transmit exif data or aperture metrics to the camera. The extreme corners are quite soft at wide apertures, and the lens suffers from visible lateral chromatic aberration, persistent corner vignetting, and a complex mustache-patterned barrel distortion. Despite these flaws, stopping down to F2.8 vastly improves edge-to-edge sharpness, making it a highly capable, reasonably priced option for budget-conscious landscape and video shooters.

The Viltrox PFU RBMH 20 mm f/1.8 ASPH lens is a well-constructed optic that provides fierce market competition at an affordable price. It features a robust, good-quality metal barrel and delivers exceptional image quality at the frame center. Optically, it excels by showing no issues with longitudinal chromatic aberration, negligible lateral chromatic aberration, and moderate distortion. Photographers will also benefit from slight vignetting on APS-C sensors and quite pleasing out-of-focus areas (bokeh). Overall, the lens offers a highly compelling price-to-performance ratio for consumers looking to fill gaps in name-brand lineups. Despite its strong value, the lens has several optical drawbacks, particularly when shooting wide open or on larger sensors. Its image quality near the maximum relative aperture on the edge of the frame leaves room for improvement. Full-frame shooters will experience very high vignetting, which limits its edge performance on large sensors. Additionally, the lens exhibits distinct coma and significant astigmatism, which may affect its performance in specialized scenarios like astrophotography.

The OpticalLimits review profiles the Viltrox PFU RBMH 20mm f/1.8 ASPH as an all-manual, ultra-wide prime lens for full-frame Sony E-mount cameras, valued as a highly affordable option under $400 USD/EUR. Its primary pros center around an excellent all-metal build quality that feels like it was "carved out of a solid piece of metal," coupled with super-smooth, well-damped control rings and a de-clicked, step-less aperture ring that appeals heavily to filmmakers. Optically, the lens delivers excellent sharpness in the dead center of the frame even wide open at f/1.8, produces very low pincushion distortion (0.5%), manages lateral chromatic aberrations well, and provides a surprisingly smooth, circular bokeh thanks to its unique 14-blade aperture design. Additionally, it includes a smart dual-hood system featuring a secondary barrel hood that accommodates standard 82mm filters despite the lens's bulbous front element. However, the lens comes with several notable cons regarding its usability and edge-to-edge optical performance. Because it is a completely manual lens without any electronic contacts, it transfers no EXIF data to the camera and entirely lacks autofocus capabilities or automatic camera-based profile...
