What is a shotgun microphone?
A shotgun microphone is a highly directional condenser mic with a long, narrow pickup pattern that captures sound from directly in front while aggressively rejecting sound from the sides and rear. It is the standard microphone for film, video production, and on-camera recording.
How shotgun mics achieve directionality
The long tube (interference tube) in front of the capsule has slots along its length. Sound arriving from the sides enters through these slots at different times, causing phase cancellation — the sound waves cancel each other out.
Sound arriving from directly in front enters the tube aligned in phase and reaches the capsule at full strength.
The result is extreme front-focused pickup — the mic hears what it is pointed at and ignores almost everything else. The longer the tube, the narrower and more directional the pickup pattern.
On-camera vs boom-mounted
On-camera (short shotgun): Compact shotgun mics (10-15cm) mount on the camera’s hot shoe. They capture better audio than built-in mics but are limited by their distance from the subject. Best for vlogging, run-and-gun, and ambient sound.
Boom-mounted (long shotgun): Professional shotgun mics (20-40cm) mounted on a boom pole and held above and in front of the subject, just out of frame. This is the film industry standard — getting the mic close to the subject while keeping it off-camera.
Boom position matters: The closer the shotgun mic is to the speaker, the better the audio. A mic 30cm away sounds dramatically better than one at 2 meters.

Shotgun mic vs lavalier — when to use each
Use a shotgun when: You cannot or do not want to attach a mic to the subject. Narrative film, documentary, event coverage, and any situation where the mic must be invisible.
Use a lavalier when: The subject is far from the camera, multiple people are speaking, or you need consistent audio regardless of head movement. Interviews, presentations, and weddings.
Use both: Professional productions often record both simultaneously as backup — shotgun on a boom plus lavalier on the subject. The editor chooses the best track for each moment.
The single biggest improvement to your video audio is getting the microphone closer to the subject. A cheap shotgun mic 30cm away will sound better than an expensive one at 3 meters. Proximity beats equipment every time.
