It depends
If the camera is facing the object in focus orthogonally and if the unimportant background is out of focus, then yes
If the camera is facing the object in focus at an angle so that the object is just slightly in focus, then no
Let me clarify
A photo I shot:
The shocks are entirely in focus because I wanted to show those entirely
The photo in the OP is also good. The photo is about the PCIe card, and it's entirely in focus
Example of bad blurry photo (though it's actually video, but whatever)
I want to see the entire shroud and fan, not just the hub
