I just wanted to add my voice as another new EOS M owner who - while I read every review that mentioned the slow AF speed - still went ahead and made a purchase.
I'm a novice camera owner. I've had a series of compact camera, had a foray into DSLRs with the Canon 300D (Digital Rebel in the USA) and have decided that my perfect camera is small, has interchangeable lenses and takes pictures like a DSLR.
The EOS M has taken amazing picture after amazing picture. The quality of the output is astonishing. Almost any creative shot I can image, it's been able to take with very little intervention from me. This is an amazing piece of kit. BUT I have small, fast-moving children. So the slow AF is going to become a big deal, I reckon.
After googling firmware updates that I hoped would fix the AF speed, I stumbled across ML and this forum.
My #1 request is that the team take a look at the AF speed. If there's any help I can provide to facilitate (money, beer, UI design, etc...), please just let me know.
