Can you focus in on a center subject and blur the background with the manual controls included with the H5?

Typically, one opens the f-stop to reduce the depth of field while maintaining focus on the subject.

The White Paper makes excellent reading.

Especially chapter 8, Esthetics: Zoom, POV, Depth of Field and Bokeh


If I may quote from it..
To get shallow depth of field - to isolate subjects from backgrounds:
  • Use low f/stops (larger apertures) [/*]
  • Use as much telephoto zoom as you can (high focal lengths) [/*]
  • Separate subjects from backgrounds [/*]
  • Shoot from as close as you can get to the subject

Compared to slrs/dslrs digicams have a much tougher time getting background blur, due to the fact they have incredibly small sensors which means the actual focal length of their lenses are tiny. And its the real focal length of the lens which is a key component of depth of field.

In other words, small sensor digicams have a vast depth of field compared to dslrs. The typical f2.8 aperture on a digicam might be the equivalent of f11+ on a dslr.

So if you where to take the same shot with a dslr and a digicam , same aperture, same equivalent zoom, the one from the dslr would have much lower depth of field, the background would be more easily blurred.
