How can I do this? Camera Zoom out until can see 2 object

[lacasrac]

My camera is on my player moving.

I need to create a box collider, when entering the player in it I want something like:

1, the camera zoom out, so we can see the plaayer and the other object too (the other object is in the bottom of the player, lets say 6 unit, so we can't see it)

2, after we saw that, the camera go to the default position, on the player.

How?
