What Is A Canon EF-S Lens?

EF-S lenses are designed specifically for Canon APS-C sensor cameras.  It is not possible to mount an EF-S lens on an APS-H, or a full frame camera.

Since crop sensor cameras do not make use of the full width of full frame lenses, you end up carrying around a lot more lens than is really necessary! EF-S lenses are lighter and smaller, because they don’t need to cover such a large image circle.

Most popular EF-S lenses: Canon EF-S 24mm f/2.8 STM Pancake | Canon EF-S 10-22 f/3.5-4.5 Canon EF-S 10-18mm f/4.5-5.6 IS STM
