Samyang 20mm F1.8 ED AS UMC (M4/3) – Ultra Wide Angle, Manual Focus, Low Light Lens, Micro Four Thirds
The Samyang 20mm F1.8 ED AS UMC (M4/3) stands as a premier ultra wide-angle prime lens engineered for creative professionals and advanced enthusiasts who demand sharpness, optical precision, and exceptional low light performance. Designed specifically for the Micro Four Thirds (M4/3) mount, this lens addresses the critical need for a fast, wide field of view in landscape, architecture, astrophotography, and video production, where edge-to-edge clarity and minimal distortion are paramount. Leveraging advanced ED (Extra-low Dispersion) glass and Samyang’s renowned UMC (Ultra Multi-Coating) technology, this lens delivers outstanding image quality with high contrast and reduced chromatic aberration, even in challenging lighting conditions.With a robust, all-metal construction and a manual focus design, the Samyang 20mm F1.8 ED AS UMC appeals to photographers and videographers who prioritize tactile control and precision over automated systems. Its F1.8 maximum aperture makes it an ideal tool for capturing detailed, noise-free images in low light environments, while the wide 94.8° angle of view (equivalent to 40mm in full-frame terms) offers a versatile perspective for storytelling. Whether shooting expansive landscapes, immersive interiors, or cinematic video, this lens empowers users to push creative boundaries without compromise.
Ultra Wide-Angle Field of View
The Samyang 20mm F1.8 ED AS UMC (M4/3) provides an ultra wide 20mm focal length, translating to an approximate 40mm equivalent on Micro Four Thirds sensors. This expansive field of view (94.8°) enables photographers to capture sweeping landscapes, dramatic architecture, and immersive environmental portraits with minimal perspective distortion. This allows creators to encompass more of the scene in a single frame—ideal for real estate, travel, and outdoor photography.
Fast F1.8 Maximum Aperture
With an impressively bright F1.8 aperture, this lens excels in low light performance, offering shallow depth of field and beautiful background separation. The wide aperture facilitates faster shutter speeds in dim conditions and creates pleasing bokeh for subject isolation. This ensures sharp, vibrant images in night scenes, astrophotography, and indoor environments without excessive ISO noise.
ED (Extra-low Dispersion) Glass Elements
Incorporating Extra-low Dispersion (ED) glass, the lens minimizes chromatic aberrations and color fringing, delivering high-resolution images with accurate color reproduction. ED elements are critical for maintaining edge-to-edge sharpness and clarity, especially at wide apertures. This translates to images with cleaner details and true-to-life colors, even in high-contrast scenes.
Advanced UMC (Ultra Multi-Coating) Technology
Samyang’s proprietary Ultra Multi-Coating (UMC) is applied to all lens elements, significantly reducing flare, ghosting, and reflections. This advanced optical coating enhances light transmission and contrast, producing crisp, high-contrast images with deep blacks and vibrant colors. This empowers photographers to shoot confidently in backlit or high-glare situations without sacrificing image quality.
Manual Focus Precision
The Samyang 20mm F1.8 ED AS UMC features a smooth, dampened manual focus ring, providing tactile feedback and precise control over focus adjustments. The manual focus design is ideal for video shooters and still photographers who require exact focus placement, particularly in critical applications like astrophotography or macro-style close-ups. This allows for accurate, repeatable focusing, even in challenging or low-contrast scenes.
Robust All-Metal Construction
Engineered with a durable all-metal housing, this lens is built to withstand professional use in demanding environments. The solid construction ensures long-term reliability and a premium feel, while the metal mount guarantees a secure connection to the camera body. This durability makes it a dependable choice for fieldwork, travel, and intensive shooting schedules.
Compact and Lightweight Design
Despite its robust build, the lens remains compact and lightweight (approximately 488g), perfectly balancing portability and performance for the Micro Four Thirds system. Its streamlined profile makes it easy to carry for extended shoots or travel, without adding unnecessary bulk to your kit. This enables creators to stay agile and mobile, capturing spontaneous moments with ease.
Rounded 7-Blade Diaphragm
A rounded 7-blade diaphragm creates smooth, natural-looking bokeh and pleasing out-of-focus highlights, even when stopped down. This aperture design is essential for portrait and video work, where background rendering and subject separation are critical. This feature helps elevate the aesthetic quality of both stills and cinematic footage.
Minimum Focusing Distance of 0.2m
The lens offers a close focusing distance of just 0.2 meters, allowing for creative wide-angle close-ups and dynamic compositions. This capability is especially valuable for environmental portraits, product photography, or capturing foreground details in landscape scenes. This lets photographers experiment with perspective and depth, adding visual interest to their images.
Optimized for Micro Four Thirds Mount
Purpose-built for the M4/3 system, the Samyang 20mm F1.8 ED AS UMC delivers optimal image circle coverage and edge-to-edge sharpness on Olympus, Panasonic, and Blackmagic cameras. Its optical formula is tuned to the sensor size, ensuring consistent performance across the frame compared to adapted full-frame lenses. This guarantees maximum compatibility and efficiency for Micro Four Thirds users seeking a dedicated wide-angle solution.
