Description
A large-aperture 50 mm prime lens is a must-have for serious full-frame camera users, and this is an excellent, affordable choice. The optical design is state-of-the-art for high image quality, and the large F1.8 maximum aperture can produce gorgeous background bokeh. On APS-C format E-mount bodies it provides equally high quality with an equivalent focal length of about 75 mm.
- E-Mount Lens/Full-Frame Format
- Aperture Range: f/1.8 to f/22
- One Aspherical Element
- Double-Gauss Optical Design
- DC Autofocus Motor
- Seven-Blade Circular Diaphragm
A simple, bright, and lightweight normal prime, the Sony FE 50mm f/1.8 is a versatile normal-length prime lens designed for full-frame E-mount mirrorless cameras. Its sleek design makes it well-suited for everyday shooting, while the fast f/1.8 maximum aperture benefits working in low-light conditions as well as offers increased control over depth of field for selective focus imagery. The optical design incorporates one aspherical element to control spherical aberrations, an employs a double-gauss configuration in order to realize sharper, clearer image quality throughout the aperture range with reduced field curvature. A DC actuator is also employed to provide quick and precise autofocus performance that is also quiet to suit video recording applications. Additionally, a rounded seven-blade diaphragm is featured to render out-of-focus highlights with a smooth, circular appearance. Characterized by its straight-forward design, this go-to lens balances both ease of handling along with enhanced image quality.

Lifelike detail, texture and gradation
An updated double-gauss optical configuration with an aspherical element minimises spherical aberration and coma for sharp, high-quality rendering throughout every frame. The double-gauss design also suppresses field curvature and distortion.
Dreamy large-aperture prime lens bokeh
A large F1.8 maximum aperture and 7-blade circular aperture work together to create beautiful background bokeh that can make subjects stand out. Placing a sharply focused subject in front of a smoothly defocused background is an essential technique for producing deep, dimensional images.
Shoot at night or in dimly lit interiors
The large F1.8 maximum aperture is an advantage when shooting night scenes or in dimly lit interiors. When used with an α series camera body that features in-body image stabilisation even greater low-light capability enables handheld capture of clear images in dark scenes without having to use excessively high ISO sensitivity.
