Overview

The Samyang 24mm f/1.4 ED AS IF UMC is a premium wide-angle lens built for Sony E-mount cameras, offering a fast maximum aperture that opens up creative possibilities in low-light photography, astrophotography, landscapes, and architectural work. Its optical formula consists of 13 elements arranged in 12 groups, incorporating 4 extra-low dispersion (ED) elements to minimize chromatic aberration and 2 aspherical elements to correct distortion and spherical aberration. Multi-layered anti-reflective coatings across the glass surfaces help suppress flare and ghosting, ensuring clean contrast even when shooting toward light sources.

As a manual focus lens, the Samyang 24mm f/1.4 features a long-throw focus ring that allows precise adjustments — a characteristic that astrophotographers and landscape shooters often prefer over autofocus for critical focusing at infinity or specific hyperfocal distances. The lens mounts natively to any Sony E-mount body, including both full-frame and APS-C sensor cameras, providing flexibility across Sony's mirrorless lineup. For photographers seeking a fast, wide-angle prime without the premium price tag of Sony's own G Master series, this Samyang lens delivers impressive optical quality and build at a compelling price point.

Pros & Cons

👍 Pros

  • Wide f/1.4 maximum aperture delivers excellent low-light performance and shallow depth of field
  • 13-element optical design with 4 ED and 2 aspherical elements controls aberrations effectively
  • Multi-layered anti-reflective coatings reduce flare and ghosting in challenging light
  • Compatible with both full-frame and APS-C Sony E-mount cameras

Frequently Asked Questions

No, this is a fully manual focus lens. It features a smooth, well-damped focus ring for precise manual focusing, which many photographers prefer for landscape and astro work.
It is compatible with both full-frame and APS-C Sony E-mount cameras. On APS-C bodies, the effective field of view is equivalent to approximately 36mm.
No, the Samyang 24mm f/1.4 does not have built-in optical stabilization. However, many Sony E-mount bodies offer in-body image stabilization that can compensate.
The wide f/1.4 aperture gathers significant light, and the 24mm focal length provides a broad field of view, making it a popular choice among astrophotographers for capturing star fields and the Milky Way.
