As I already wrote in my post above, due to the larger sensor, you have an issue with DOF. ...As we all know, pixel sharpness depends on the lens used, and not all lenses on dSLRs give maximal resolution....

An f stop of 7.5 would have given the same field of view. The f/5.6 that was set was probably adequate, but one more stop would have been more would have sufficed for sure. I think the problem is that nothing is really sharp in the photo. I think the problem is either camera motion or lens sharpness.  The phone used a very fast shutter speed, which is why it underexposed the picture.

Where the smartphone clearly has the advantage is that it can use a lens that is optimised for the small sensor....

The lens is shown as 17-50 mm, which is not a Canon lens as far as I know.  But it is probably an EF-S lens, which presumably is optimized for small sensor.
