Well, honestly: the Canon Sx720 has a small-sized, but 20.3 million pixel sensor; due to the small physical size of the sensor, it will not do the in focus people/blurry backdrop type of pictures at close distances, the way say a 35mm SLR or a medium-format SLR would do, or a full-frame digitial SLR, or even a crop-frame d-slr. Buuuuuuut, on the other hand, the digicam type cameras can do somehting people have wanted to be able to do for over a hundred years, and that is to achieve "deep focus", with relative ease...without the need for split-diopter filters, or for camera movements with a view camera and the Schiempflug principle, or for stopping to to f/64.
What some might see as a dis-advantage, can easily become a major source of strength in scenic and landscape and social photography. Social photography, like on the street, or in a diner or restaurant, or at a carnival, etc.; the ability to have a SHARP, clear picture across a wide span of distancs, from fairly close, all the way to 50 meters, and out to nearly Infinity...THAT is the province of the digicam.
And also: the Sx720 has that ****incredibly long**** maximum zoom setting for a digicam. I recall taking a shot of my son and his mother from about 50 meters with her red 720...I was like, "WOW! This is one hell of a looooong zoom lens!" I mean, I would reckon it is like a 600 or 800mm equivalent on FX...it is a POWERFUL zoom....
So, focus on the strengths the camera has. If you absolutely WANT a defocused background on a portrait, learn the modern ways to do defocusing in software. But be aware that, for over 100 years or more, getting deep,deep focus was often a goal of many.
