The EF-M 22mm f/2 STM is currently the only prime lens designed for the EOS-M line of cameras (I say “line” because the EOS-M2, the second camera in this series, is on the market in Japan at the moment, hopefully to expand to other markets soon). It is also by far the fastest and smallest EF-M lens (at .9″ long), and the only EF-M lens without image stabilization. But perhaps the most remarkable thing is it’s also a macro lens, and a very good macro lens at that.
With a minimum focus distance of 5.9″ (.15m), the EF-M 22 produces a magnification of .22x with excellent sharpness, even at f2, as the gallery below shows.
This lens is currently available for $124 by itself, or as part of a kit with the EOS-M camera body ($445), though the kit, at this time, is overpriced relative to the same kit with the 18-55 STM ($360). If you happen to like the camera body in red, there’s a great deal on the kit with the 22mm lens for $369 right now
Browse through the gallery below, and keep in mind this is the bare EF-M 22mm f/2 STM without extension tubes or other modifiers. Each picture is at minimum focus distance, the first picture representing the full FOV, and the 2nd picture a 100% crop detail.
