What does Canon EF-S stand for?
Electro-focus short back focus
EF-S stands for Electro-focus short back focus. This Canon lens mount was launched alongside the EOS 300D (EOS digital Rebel) camera in 2003. EF-S lenses have an image circle which just covers the sensor of APS-C cameras, meaning that the image circle is smaller in size than in EF lenses.

WHY is USM more expensive than STM?
