I’m learning photography with a Nikon D7000 and the 18-105mm f/3.5-5.6 kit lens. I want to make portraits with a blurry background, but so far most of my photos have everything in focus.

Can this lens produce a shallow depth of field? If so, what settings and shooting technique should I use to get the strongest background blur?

I gave pretty much the same answer before, but here it is again for completeness. To minimise DOF and get the blurred background effect you should:

  • Use as long a focal length as possible.

  • Use a wide aperture low f/ number (but don't zoom out increase the f/ number as the actual lens opening gets no bigger)

  • Use as close a focussing distance as possible (but don't zoom out to get closer). Depth of field diminshes very quickly with focus distance, so much so that it becomes a major problem with macro photography getting a non blurred background (or subject!)

  • Compose so that the background is as far away as possible. The further away objects are from the focussing distance the blurrier they will be.

Yes — you can get background blur with that kit lens, though it will be more limited than with a faster prime lens.

To get the shallowest depth of field possible:

  • Use the longest focal length you can, around 100–105mm.
  • Use the widest available aperture at that focal length, which is about f/5.6.
  • Move as close to your subject as you can without causing awkward perspective or distortion.
  • Keep the background as far behind the subject as possible.
  • Use Aperture Priority or Manual mode so you can keep the lens wide open.

The key is subject distance and background distance: close subject + distant background = more blur.

At the wide end of the lens, even though the f-number can be lower, you’ll usually get more depth of field, so wide-angle shots tend to keep more of the scene in focus. For portraits, the telephoto end is usually better.

So: yes, it’s possible with your kit lens — try 105mm, f/5.6, get close, and avoid backgrounds that are near your subject.
