What's the difference between canon port and e port?

Differences in application fields, structure and function, manufacturing and design.

1, application field: Canon port is a camera lens bayonet, which is mainly used to connect the camera and lens, and is an important part in the field of photography. Electronic bayonet is a kind of electronic equipment interface, which is widely used in traffic management, safety monitoring and other fields to automatically detect and record vehicle information.
