There's no such thing as the "right" lens, just the "right" lens for your story.
Your job as a filmmaker is not just to capture images that are beautiful, but to capture images that tell stories. There are many ways to do this through composition, color, and camera movement, but what about lenses? What kinds of lenses should you use to evoke certain emotional responses?
In this video, Matti Haapoja of Travel Feels explains how different lenses inspire different emotions in audiences and how you can use them to tell better stories.
Before you ever choose which lenses you're going to use for a scene you're should always ask yourself this question first: "What mood and/or emotion am I trying to create?" Once you nail that down, it's just a matter of understanding how different lenses change the relationship between the subject and the background, as well as which lenses produce which feelings and tones.
Wide angle lenses are great for many different kinds of scenes. Not only do they make us feel "closer" to a subject, almost like we're there in the scene with them, but their natural distortion of the subject works well for scenes depicting drunkenness, madness, and fear.
Telephoto lenses tend to give a more withdrawn feeling from the subject because the subject feels further away in the frame, which means they're great for creating an observational perspective. You're not putting your audience right in the scene with the subject or putting them into a surveilling POV; you're putting them somewhere in the middle where they are simply spectators watching the events unfold.
More neutral lenses, like 24mm, 30mm, and 50mm work well if you want to keep your point of view objective and natural. (24mm is slightly wide-angle, so just keep that in mind.)
But it's not just about focal length. Your camera's distance from the subject, as well as foreground elements can change the way your audience responds emotionally to a shot pretty easily. An objective, observational shot with an 200mm lens can quickly become a creepy, voyeuristic POV just by simply putting a tree, a door, or a window between the camera and the subject or by capturing the scene from further away.
