Default Shallow depth of field with CP5700

Is it possible to get a shallow depth of field with CP5700 for instance for taking portraits?

Portrait can be taken in many ways.

Lets suppose there is enough light in the room you will use - otherwise use a tripod or flash

You have to use the zoom - almost zoom all the way out - then choose an aperture as little as possible i.e F2.8, this will blur the background and get the face sharp.

This works best on outdoor shots under good lightning conditions, because you will be able to have a fast shutter ( 1/60 should be enough for a steady hand).

So...as little F. number as possible and not less than 1/60 of a second in shutterspeed. The DOF depends on the aperturesize!

Have you tied this with the CP5700?
Does the size of the CCD have any influence in the depth of field? The size of the CCD is 2/3" for the CP5700?

As you can see below I also own the CP5700 and I've tried this many times. It's not that hard and works fine. But of course you have to be familiar with the cam.

Why do you ask about the CCD ? What's the gain ?

I have a CP880 and the depth of field is large even with F2.8 and max zoom ( 2.5x is not enough...). I heard that with a small CCD the depth of filed will be larger than with a larger CCD. Is this right?

Does the DOF also depend on focal length?

Hmmm...Strange thing to ask about! The CCD!
The answer to your last question is - Yes!

It's hard to get the level of the shallowness of DOF as on SLR camera, but it can be done. Klaus already mentioned everything above, by using the smallest f number at the current focal length (longer focal length is the better). Make sure there's enough distance between the object and the background (prosumer digicam has wide dof, the only thing to make background out of focus is by making the main object far enough from the background).
