Your camera lens may or may not have the “mm” printed on it. You will see a number, a slash, and another number (# / #). The second number is the focal length.

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.
Can I use EF-M on EF?
This Canon EF-M Mount Adapter lets any EF or EF-S lens mount and work perfectly on EOS-M cameras. It works with all Canon autofocus lenses made since 1987. I tried with a 1980s EF 50mm f/1.8 which worked perfectly, as well as the classic EF 35mm f/1.4 L and the hot new EF 24-70mm f/4 IS.

All EF and EF-S lenses can be used by attaching the optional Mount Adapter EF-EOS R. The camera cannot be used with EF-M lenses.
Is F2 8 or f4 better?
