Canon fanfiction aims to expand on the existing world and characters, while non-canon fanfiction explores creative "what if" scenarios outside of the established canon. **

EF lenses can be used on both full-frame and crop sensor Canon bodies, while EF-S lenses are designed specifically for crop sensor bodies.

Therefore, it's important to ensure compatibility between the lens mount and the camera body before purchasing or using a lens. **
