I have loaded the ML in my new EOS M and found the Shutter Problem all the Rest is Fine I read the Threads and turning On Off Quickly resolves the Problem and If I remove the Lens and put it back the Shutter works. this happens only when I use the factory 18 to 55 mm when I use the Lens adaptor and use the Other Canon Lenses it works every time. Hope this info helps till we get the Bug Fixed. the Rest is Good Stuff. thanks Guys.
