Canon EF-M 22mm f/2 STM lens
In addition the EOS M body two lenses are being released, a 22mm f/2 wide angle and an 18-55mm f/3.5-5.6 standard zoom lens. The Canon EF-M 22mm f/2 STM lens is equivalent to that of a 35.2mm lens in full-frame format. It has maximum f/2 aperture to aids in low light and action shooting. It features one aspherical element for aberration reduction and a circular aperture with 7 diaphragm blades for a soft out-of-focus quality.
The EF-M 18-55mm f/3.5-5.6 IS STM lens is a standard zoom lens equivalent to a 28.8-88mm lens in 35mm format. makes it a versatile lens for many different situations.

Canon EF-M 18-55mm f/3.5-5.6 IS STM lens
This lens is constructed with 3 aspheric lens elements for minimizing lens flare and ghosting as well as providing greater image quality. It is also equipped with dynamic IS to provide the image stabilization during recording video while walking and provides up to a 4-stop equivalent reduction in camera shake.
Both of these lenses feature STM or stepping motor technology for improved autofocus capabilities with HD video. The STM provides extra smooth, quiet auto-focusing to reduce internal mechanical noise and smoother transitions while changing focus while recording.

Canon EF-M Adapter For EF & EF-S Lens
Besides these two lenses, you can make use of the entire Canon EF range with the EF-M Lens Adapter for full compatibility with both EF and EF-S lenses. The design of the adapter inccludes a tripod collar for use with some of the longest telephoto lenses and it also fully supports all image stabilization and autofocus types found throughout the EF series.
