env_zoom is a point entity available in all Source games. It can be used to control the player's FOV. Useful for scenes where the player's view is being controlled, or player-usable binoculars/telescopes, etc.

Since Half-Life 2 20th Anniversary Update, this entity is used on all background maps, locking the viewer's FOV to 75.

Bug:Does not function in , and possibly most multiplayer games.
