What are the differences between EF-S and EF lenses, and how do they impact the performance of a camera?

EF-S lenses are designed specifically for Canon APS-C sensor cameras, while EF lenses are compatible with both APS-C and full-frame sensor cameras. EF-S lenses are generally smaller and lighter than EF lenses, but they have a more limited range of focal lengths. EF lenses offer a wider range of focal lengths and are typically higher quality, but they may be larger and heavier. The choice between EF-S and EF lenses can impact the performance of a camera by affecting the field of view, image quality, and overall versatility of the lens system.
