Lens Review : Samyang AF 50mm F1.4 FE


Samyang’s first autofocus standard lens developed for Sony E-mount cameras

The collection of lenses from the Korean manufacturer Samyang has been ever increasing and has been making its status as an important lens maker in this niche field that requires high technology. With the increasing market share of the E-mount users, Samyang, naturally, foresee this opportunity to jump into the E-mount bandwagon to make value for money alternative lenses, especially for the A7 series users. The AF50mm F1.4 FE is the earliest lens made for the E-mount.

Characterized by its autofocus operation, the AF 50mm f/1.4 FE Lens from Samyang is a fast normal-length prime for Sony E mirrorless cameras. Its bright f/1.4 maximum aperture is well suited to controlling depth of field for selective focus imagery, and also suits working in low-light conditions. The optical design incorporates three aspherical elements to minimize spherical aberrations for cleaner, clearer image quality and an Ultra Multi-Coating has also been applied to limit flare and ghosting when working in strong lighting conditions. The lens’ autofocus motor works in conjunction with Sony cameras’ AF systems for quick and precise focusing performance, and manual focus override is also available for more refined control. A versatile normal-length lens, this lens mixes a fast, bright design with autofocus to present an ideal all-around optic.


This is a standard prime designed for full-frame Sony E-mount mirrorless digital cameras for it to take full advantage of the design, however, this lens can also be used on APS-C models where it will provide a 75mm equivalent focal length. It offers bright and fast f/1.4 maximum aperture which excels in low-light conditions and also affords increased control over depth of field for working with selective focus techniques. No doubt, this lense is great for portraits shoot that deliver nice bokeh, thanks to its rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. In the barrel, three aspherical elements are incorporated in the optical design to control spherical aberrations for increased clarity and resolution from edge to edge. On top of that, an Ultra Multi-Coating has been applied to individual elements in order to reduce flare and ghosting for increased contrast and a neutral colour balance.

The integrated autofocus motor works in conjunction with Sony cameras’ focusing systems for quick, accurate, and precise AF control. Manual focus override is also available if you want to fine tune your focus position.

lens-review-samyang-af-af-50mm-f1-4-feGreat handling with its 47-degree viewing angle. Performed really well in low light and generating smooth bokeh. This is a must-have standard lens if you want to skip the G Master version from Sony Performance and image quality are impressive.
