Canon Patent for 9-18mm Ultra-Wide Angle Lens for EOS M

9.18

Egami (translated) spotted a patent for an EF-M 9-18mm f/3.5-4.5 STM lens for the EOS M system. A bit weird since there is already the excellent EF-M 11-22mm f/4-5.6 IS STM lens. I guess this is just one of the many patents Canon is filing and not a lens that will hit the market anytime soon.
