I am looking to trade my mint condition Canon EF-S 10-18mm f/4.5-5.6 IS STM lens with a genuine Canon EF-EOS M Mount Adapter (with tripod mount) for a Canon M mount 11-22mm or Canon 22mm F2 (plus little bit of cash from your end) lens. You get a wider lens plus the ability to use all the Canon EF and EF-S lenses on your M mount camera. I will also include a variable ND filter for it. Thanks for looking. Canon m5, m10, m100, m50, 70d, 80d
