I came across this video breaking down focal length in cinematography, and it does a beautiful job of connecting the physics of lenses to how we feel a scene as viewers.
One of my favorite takeaways is when you watch a film, you’re not just looking through a camera, you’re looking through a point of view. That point of view, expressed as focal length, shapes depth, intimacy, tension, and even how close or distant we feel from a character.

The video walks through:
Why wide lenses feel immersive and immediate, but can distort space and faces
Why 35mm–50mm often feels “honest” or observational
How long lenses compress space, isolate characters, and create tension or surveillance-like distance
Why focal length choice directly affects depth of field and focus pulling difficulty
How format matters: Super 35, 16mm, and full frame all change how the same lens feels
It also ties focal length to filmmakers we all know:
Emmanuel Lubezki using extreme wides to bring us into the world
Yasujirō Ozu favoring the 50mm for quiet, honest observation
Safdie Brothers and Michael Mann leaning into long lenses to create pressure, chaos, and alienation
What I really appreciate is the reminder that focal length is a storytelling choice, not just a coverage decision. Every lens subtly tells the audience how to feel; connected, distant, vulnerable, and watched.
Do you have a focal length you instinctively gravitate toward?
Have you ever changed a lens choice and felt the emotional shift immediately?
When you’re planning a scene, do you think about focal length emotionally first or practically first?
Would love to hear how you all approach lens choice on set.
