It would be nice if all review samples started with a portrait shot like this one, but at wide open aperture so we can appreciate the bokeh of the lens/sensor combination.
c'mon now, why would you want to shoot a portrait at f1.4?! when background is busy, always shoot f10?
The background is part of the shot and captured nicely without being distracting. A wider aperture would have turned it into a distracting mush. An aperture of f1.4 would not even have got the whole model in focus. It's good to know the photographer understands these things.
