Even with the 22mm STM lens, it takes a second or two.  The 18-55mm STM is said to be reasonably fast. 
The new Hybrid AF system is not optomized for use with the non STM lenses, so AF speed will be dismal.
Take into account what may be a lower voltage battery, and there is less current to drive the AF motor.
Other than him trying to focus on the table at much closer than MFD, I was suprised that the camera focused as fast as it did.

Focus seemed to be faster when using the center point(s). The corners of the frame rely on the (much) slower contrast-detect focus, and that's what this user was using so it makes sense. How does it do with a regular EF lens when focusing with those center points?

Also, I wonder how tough it would be to get a sharp image particularly since you are forced to hold the camera away from your body, which removes one aid in stabilization. Particularly with longer non-IS lenses (say, 85 1.8 ), probably would need pretty fast shutter speeds, I would take it? Hopefully an EF-M lens in the 60-80 mm range with IS materializes to fill this gap.

Perhaps a EF-M telephoto option (even the EF-S 55-250 looks pretty ridiculous on that tiny camera, haha) might be in the works too, but that wouldn't really matter to me personally anyway.

If the dslr ran out of battery its totally gonna get owned by this
But to be honest with how slow shooting in live view is I wasn't expecting a whole lot
