There are many uses for shallow DOF. One is to isolate your subject from an uninviting BG. Another is to emphasize your focal point or focus plane. Since I was stuck indoors due to weather I did a simple field test showing the difference between f1.4 and f2.8. Both shots were with a D700 85mm/f1.4G prime lens from 6 feet. ISO was 1600. White balance was accomplished using an Expodisc. I did similar shots at 1.4;1.8;2.0;2.5;2.8; and 3.2 but I am only showing these two.
The focus plane for this test was the nose tip of the stuffed animal. At 1.4 there is about an inch or less of sharpness. At 2.8 you have more separation before sharpness greatly diminishes. Notice the BG of both shots and notice the OOF even on the front of the stuff animal at 1.4. There are applications for shooting at 1.4, but your focus has to be spot on.
