Hello Haruto, and welcome to the POV-Ray newsgroup.

POV-Ray alows you to change the distance from the camera to the viewing
plane using the 'Direction' vector of the 'Camera' object.

I still use this in preferance to the angle keyword. Most of my scenes are
built with  direction <0,0,1.45> - this seems to give a natural kind of
view.

Hope this helps.
