    Hi Diego…

    You’re battling pure physics and optics there. The smaller the size of the sensor in a camera, the greater the depth of field will be. Your camera has a very tiny sensor, therefore depth of field is almost infinite. Even if you open up the iris fully (outdoors or indoors) you depth of field is going to be very very deep.

    Shooting with as long a focal length as possible (i.e., “zoom in”) will decrease the perceived depth of field a little bit, but of course that dictates your composition and framing.

    The only real way to truly get a shallow DoF with a small camera like yours is to use a 35mm lens converter and shoot with cine lenses or 35mm SLR (still camera) lenses.

    This has been discussed a great great deal here in recent months in various COW forums (some would say ad nauseum, so much so that it became a little bit of a sore subject for a couple of people). Do a COW search for “depth of field” and you will find a huge number of posts about it.
