Canon EF 50mm f/1.8 STM Lens: Reviews, Specs, and Buying Guide

Unlock stunning low-light photography with the Canon EF 50mm f/1.8 STM lens. Its wide f/1.8 aperture captures over eight times more light than a standard kit lens, delivering sharper images with reduced motion blur and less need for flash—so you can effortlessly capture the true atmosphere of any dimly lit environment.

The classic 50mm focal length provides a natural perspective similar to the human eye, making it perfect for portraits where you can frame your subject beautifully from a comfortable distance. Compact and lightweight, it’s an ideal everyday lens to always have on your EOS camera.

Harness the power of near-silent STM (Stepping Motor) technology for extremely fast and quiet focusing. Seize fleeting moments in photos with responsive autofocus, and create smooth, professional movies with steady continuous focus that won’t disturb your soundtracks with motor noise.

This lens builds on the legacy of the popular EF 50mm f/1.8 II, offering the same exceptional image quality at an affordable price, but now with a faster, quieter focus motor and a more durable build. Featuring a circular 7-blade diaphragm for gorgeous background blur, advanced lens coatings for excellent color balance with minimized ghosting and flare, and a rugged metal mount, the EF 50mm f/1.8 STM is your gateway to creative versatility.

Specifications: Focal Length: 50mm (80mm equivalent on APS-C). Maximum Aperture: f/1.8. Lens Construction: 6 elements in 5 groups. Closest Focusing Distance: 1.15 ft. (0.35m). Filter Size: 49mm. Dimensions: Approx. 2.7 x 1.5 inches. Weight: Approx. 5.6 oz.

With a bright f/1.8 maximum aperture and a classic 50mm focal length, this lens excels in crafting beautiful portraits, capturing fast action, and mastering low-light scenes. Its 46-degree angle of view provides a natural perspective, while a close 1.15-foot minimum focus allows for engaging detail. A near-silent STM stepping motor ensures smooth, continuous autofocus for both video and stills. The optical design, with 6 elements in 5 groups, delivers sharp results, offering an effective 80mm focal length on APS-C cameras and a true 50mm field of view on full-frame.
