Sniper scope zoom help

Hi, I’m not sure if this has been asked before, but I’m making a game with a sniper rifle and I want to make it so that when you go to the scope it zooms in so you can see farther. Thanks for any help.

Add a new camera, in the same position as the old one, parented to it. But change the lens size to make it zoom in. (under editing tab, the one that says lens: 35) Then use the logic bricks to change between cameras.
You can also make it add an overlay scene to represent the scope/crosshairs.

yeah, you go into the properties of the camera, start with default zoom, and press [i] over the camera properties, then get to 20 frames later, and press [i] when you have set the zoom to more.
