Review

The Samyang 20mm F1.8 ED AS UMC is a wide-angle prime lens designed for the Sony E mount, making it an exciting option for photographers looking for versatility in landscape, astrophotography, and architectural shooting. With its fast maximum aperture of f/1.8, this lens offers excellent low-light performance, enabling you to capture stunning images in challenging lighting conditions.

One of the standout features of the Samyang 20mm is its optical design. The lens incorporates 13 elements arranged in 12 groups, which includes three extra-low dispersion elements and two aspherical elements. This design not only helps in minimizing chromatic aberrations but also contributes to achieving sharpness across the entire frame, even at wide-open apertures. The result is a lens that produces clear and detailed images with minimal distortion.

When it comes to handling and build quality, the Samyang 20mm F1.8 is solid yet lightweight. Weighing in at only 1.2 pounds, it’s easy to carry, making it a great companion for long shoots. The lens features a smooth manual focus ring that provides precise control, although it lacks autofocus, which might deter some users looking for convenience in fast-paced shooting scenarios.

Another aspect worth mentioning is the lens's lens hood, which helps prevent flare and ghosting, enhancing your images even in backlit situations. The lens also has a weather-sealed design, offering additional protection for outdoor photography, which is always a plus for those who find themselves in unpredictable conditions.
