Crash Zoom In

The lens snaps shut on a subject in a fraction of a second. It reads as an exclamation mark, and it is one of the few camera moves an audience registers as a joke or a shock rather than as coverage.

The speed does something no dolly can. There is no travel to follow, so the tight frame simply arrives, and the cut to it happens inside one continuous shot.

The whole lens travel runs in under a second, with a hard stop. Radial blur through the middle of the move is part of the look, since a real crash zoom on a long lens smears.

The stop is the punctuation. A crash zoom that eases into its final frame stops being a crash and becomes a rapid zoom.

The frame it lands on has to be composed. It arrives fast and stays, so a badly framed end shot is very visible.

Use it on a reaction, a reveal, or a gag. It suits comedy, action and anything with a knowing tone.

Use it once. A second crash zoom in the same scene stops reading as emphasis and starts reading as a glitch.

It also works as a punctuation mark between two shots. Landing the snap on the last frame before a cut gives the edit a push, which is why action and comedy use it at the end of a beat.

A dolly in moves the camera through the room, which takes time and changes the relationship between near and far objects. A crash zoom in changes the lens in an instant and keeps every plane locked together.

The blur tells you as well. A crash zoom smears radially from the centre. A fast dolly blurs along the direction of travel and shows parallax at the edges.

Quentin Tarantino snaps the lens in throughout Django Unchained (2012), borrowing the move from the spaghetti westerns and exploitation films it belongs to. Wes Anderson uses the same speed for comic timing in The Grand Budapest Hotel (2014), where the snap lands on a face like a beat in a sentence.

Models deliver a push in, because forward travel is what they associate with getting closer. Say snap zoom, under one second, camera body does not move.

The second failure is a scene full of them. Ask for one, on the named beat, and say the frame holds afterwards.

A third problem is a soft landing. Say hard stop, since a crash zoom that eases into its frame is a rapid zoom with a different label.
