Yongnuo 50mm f/1.8 Standard Prime Lens for Canon DSLR Cameras with Full-Frame Compatibility

This Yongnuo 50mm prime lens is a standard fixed focus lens designed for enthusiasts and professionals who value a natural perspective and a fast aperture. With a maximum aperture of F1.8 and a minimum of F/22, it suits a variety of shooting conditions from indoor portraits to bright outdoor scenes. The lens features a 6-element, 5-group optical construction and a 52mm filter thread, while its compact dimensions (73mm diameter x 55mm length) make it a practical addition to any camera bag. It is compatible with Canon bayonet mount DSLR cameras and works on full-frame bodies for its intended 50mm field of view, or APS-C bodies for an equivalent 80mm portrait length.

Features and Optical Construction

Built around a standard focal length, this prime lens is engineered to deliver contrast and clarity across the frame. The optical design uses six elements arranged in five groups to control aberrations and maintain image quality.

6-Element, 5-Group Optical Design

The lens construction comprises 6 lens elements grouped into 5 sets. This design helps reduce chromatic aberration and improves light transmission for consistent results in portrait and general photography.

F1.8 to F/22 Aperture Range

A wide maximum aperture of F1.8 allows for effective subject isolation and better performance in low light. The minimum aperture of F/22 gives flexibility for landscape or group shots where greater depth of field is desired.

52mm Filter Thread

The front of the lens accepts 52mm filters, including UV, polarising, or neutral density types, enabling creative control over exposure and reflections without needing step-up rings.

Size, Compatibility, and Practical Use

With a diameter of 73mm and a length of 55mm, this lens is physically compact, making it easy to carry and handle during extended shoots. It mounts directly onto Canon EF or EF-S bayonet bodies.

Compact Dimensions for Portability

Measuring approximately 73mm in diameter and 55mm in length, the lens does not add excessive bulk to the camera system, suiting travel and everyday photography.

45cm Close Focusing Distance

The lens can focus as close as 0.45 metres from the sensor plane, allowing for tightly framed portraits and detail shots while maintaining the working distance needed for studio setups.

No Image Stabilisation

This lens does not include built-in image stabilisation. Users should either use a tripod or ensure a shutter speed faster than 1/50th second to avoid motion blur from camera shake.

Benefits and Buying Value

As a standard prime, this lens offers a classic perspective at an affordable price point. Its wide aperture and simple optical formula provide quality results for portrait and general use.

Portrait and People Photography

The 50mm focal length on full-frame captures natural proportions for head-and-shoulders and three-quarter portraits. The F1.8 aperture creates shallow depth of field, helping to separate the subject from the background.

Versatile Standard Lens

A 50mm field of view is considered a 'standard' perspective, close to what the human eye sees. This makes the lens suitable for street photography, events, and everyday snapshots.

Affordable Prime Option

This Yongnuo lens provides a cost-effective way to add a fast prime to a Canon camera kit, especially valuable for beginners or those on a budget who still want the benefits of a wide-aperture prime lens.
