About the Canon EF-M 22mm F/2.0 STM

A great match for your Canon EOS M series camera

The Canon EF-M 22mm STM lens pairs with your EOS M series camera for an irresistibly low-profile system that can go with you anywhere. This fast lens has a minimum focus distance of just 5.9", making it ideal for close-up work in addition to wide shots. Its large maximum aperture gives you dreamy blurred backgrounds for stunning portraits and enhances low-light performance so you can use it for indoor shots without flash, as well as twilight scenes outdoors. The lens's stepping motor makes autofocusing smooth, fast and quiet, so it's perfect for moviemaking too.
