How does Nikon D710018-140 lens discharge background blur?

Background blur is a requirement for your photography skills, and you don't need to change the lens. Blurred three elements: long focal length, short distance and large aperture. For you, use the 140 terminal as close as possible to the subject, and use the aperture of 5.6, as long as there is a little distance between the person and the background, you can shoot.

The following photos are taken at close range, 100mm end, F4 aperture, using aperture priority mode. The blurring effect is very good.
