Nokishita suggests that Canon might very soon announce the Canon EF-M 32mm f/1.4 STM lens for the Canon EOS M system. A welcome addition to the EF-M lens lineup in any case. This will be the fastest Canon lens for the EOS M system.
A new and fast prime lens for the Canon EOS M system was rumored since a while and an announcement expected. A much needed lens for the EOS M system, in my opinion. So far the EF-M 22mm f/2 STM pancake lens was the only Canon offering if you wanted a fast prime with auto-focus. Other manufacturer make manual focusing lenses up to f/1.2 with native EF-M mount.
