The EOS-M kit comes with a new EF-M mount 22mm f/2 STM lens. This is a compact “pancake” lens that offers the 35mm equivalent of a 35mm lens. It’s an ideal focal length prime lens to start this new system, and it’s small enough to carry anywhere. Of course, the best thing about Canon bringing their first mirrorless camera to the market is that the full range of Canon EF and EF-S lenses are now available to use on a compact digital camera system. An optional EF lens adapter is needed to use this great line of Canon lenses but the creative possibilities are endless.
