how can a camera zoom into a game object?

[DocYesh]

Hello.
I am working on making a quiz which asks students to label the bones on face. Well, i want the camera to zoom into the object of interest when the game object in question appears and get back to default position at the end of it. How can i achieve this. I have tried look at, cameraFacing Billboards and all. But nothings working.
all i have got till now is a list of 10 bones, they are separate game objects, which change their colour when a question describes about them. I want the camera to rotate to show the game object of interest.

A script with a “target transform” and “transform.lookat(target)” (see scripting ref)

And then you change that target whenever you want to lookat something new.

Or position the camera a some preset positions. Each bone has a child empty gameobject to mark where you want the camera to be. Then you can put these in an array (to easily choose the one you want) and set “transform.position=target.position” and “transform.rotation=target.rotation”.

Use camera.main.fieldOfView
reduce the field of view to get zoom in effect and increase the field of view to get zoom out effect
