Patent: EF-M 22-46mm f/3.5-5.6

Patent: EF-M 22-46mm f/3.5-5.6

A patent which appears to be for the EF-M mount has appeared. In APS-C, this lens would be a 35-75mm f/3.5-5.6.

Canon has stated that more lenses are coming for EOS M, and that could potentially mean the North American and European markets are still on Canon’s radar for the EOS M system. My bet is we’ll see an EOS M3 to re-introduce the product line to a global market.
