A wide aperture lens for high quality portraits and low light photos
With the Canon EF 50mm f/1.8 STM lens you can easily produce more artistic and impactful photography thanks to a wide f/1.8 aperture that produces sharp focus on your subject and a beautiful blurred background.
The Canon EF 50mm f/1.8 STM lens is great for:
Artistic and impactful photography
The wide f/1.8 aperture of the Canon EF 50mm f/1.8 STM gives you the ability to bring your subject into sharp focus and blur the background. Photographers refer to this as a ‘narrow depth of field’ and makes your subject stand out which is great for portraits, as people become the clear focus of your shot.
Let more light in
The wide f/1.8 aperture lets in more than 8x the amount of light compared to the standard zoom lens that is provided with your EOS*. This results in sharper images with less motion blur and reduced need to use flash in dimly lit conditions so you can easily capture the atmosphere of a low light environment.
For portraits and everyday use
The 50mm focal length allows you to fill the frame with your subject from a comfortable distance making it a great lens for portraits. A similar perspective to the human eye and its compact size make the Canon EF 50mm f/1.8 STM a great everyday lens to always carry with your EOS camera.
Sharp focus for photos and videos
The near-silent STM (Stepping Motor) technology focuses extremely quickly when shooting photos, so you can react suddenly to capture fleeting moments. Creating high quality movies is easier with STM as it delivers steady and quiet continuous focusing, so your movies are smooth, and soundtracks only capture the surrounding sounds and not the noise of a focusing motor.
A classic re-born
The Canon EF 50mm f/1.8 STM replaces the popular EF 50mm f/1.8 II lens which was affectionately known for giving outstanding picture quality at an affordable price. This latest version gives the same stunning photo quality but with a fast, near-silent focus motor and a more robust build that belies its price.
