Zoom out = View acting wierd ?

Hey All,

I’ve made a simple scene of a plane and 3 other primitive shapes, So far so good.

The Problem:
When I zoom out with the camera, the scene goes away and disappear… when I zoom in it’s back.

Is it a bug, or a problem I can fix somehow? maybe a camera properties (I didn’t touch anything, it’s all default).

Thanks ahead!
