Sony FE 50mm f/1.8 Lens

The Sony FE 50mm f/1.8 is a compact, fast prime lens tailored for full-frame E-mount mirrorless cameras. Its classic 50mm focal length offers exceptional versatility across numerous photographic scenarios, while the f/1.8 aperture delivers an optimal blend of low-light performance and manageable size. This lens combines efficient design with reliable optical quality, making it a dependable choice for professionals seeking clarity and responsiveness in a lightweight package.

Optical Design

The lens features one aspherical element to effectively minimize astigmatism, field curvature, coma, and other monochromatic aberrations. Its double-gauss optical design reduces field curvature and distortion, ensuring consistent image quality across the entire frame. The bright f/1.8 aperture not only enhances depth of field control and low-light capability but also enables a compact and lightweight construction, ideal for everyday use and walkaround photography. Additionally, the rounded seven-blade diaphragm produces smooth, attractive bokeh for refined selective focus effects.

Autofocus and Physical Design

The lens utilizes a DC actuator motor to deliver fast, silent, and precise autofocus, making it well-suited for both photography and videography. With a minimum focus distance of 45cm and a maximum magnification of 0.15x, it is capable of capturing close-up subjects effectively. The metal bayonet mount enhances durability and provides a secure, robust connection when attaching the lens to the camera body.
