I am looking to enter in the mirrorless world,after years on analogic cameras and point and shoot. I ve seen lots of fantastic devices, but for budget reasons, and since i have already owned some of their cameras i have chosen to buy a canon (although there aren t a lot of ef m lenses). Now i am not sure what to buy between the eos m (used) or a brand new m10. I was going for the m, with i could spare enough money to buy another lens, though i heard about the af problem and i am not so sure anymore. Any advice?
