This was back in July of 2014, but a friend and colleague of mine tested this camera on me. 

The settings were on ƒ/1.4 and it did a short focus. He says he should have stopped up to ƒ/16 given the available light. He wasn't used to using camera's so early in the day. That's the thing about getting used to auto focus, P, AV and TV modes on Canon SLRs; when you go to a camera like this you are forced to think about all the other stuff.
