Shallow Depth Of Field


Sometimes you really don't want depth of field. In this case it is the very narrow plane of focus that makes the image, or to be more accurate, it is the blurred shapes in the background that do.

f5 at 200 mm.

Hi,
Iam very interested in taking images (still life and potraits) at very shallow depth of field.Any suggestions on lens types?

Lenses to minimize depth of field need to be fast and or long. The smaller the sensor, the faster the lenses need to be. With consumer cameras having half inch sensors or smaller, really blurred backgrounds really only happen at macro distances. Even APS-C size sensors have noticeably more depth of field than full size sensors so will require faster lenses. An inexpensive way to get a fast lens is to use a 50 mm. so called normal focal length lens as they typically open up to f1.8 or faster, on a small sensor slr are equivalent to an 85 mm. lens and they are cheap. Stopped down to 2 or 2.8 they still have shallow depth of field.
