EF-M compact lenses
The EOS M100’s small profile is reflected in the design of the EF-M lenses, which the camera has been tailored to use. The lenses are smaller than the EF/EF-S lenses normally used with DSLR cameras. The camera is supplied with EF-M 15-45mm and 55-200mm lenses, giving good coverage for wide- and medium-field photography. EF/EF-S lenses/ T-rings can be attached using an optional EF-EOS M adapter, which costs £104.99.
