Burst mode (also called continuous shooting mode) lets your camera fire multiple frames in rapid succession for as long as you hold the shutter button. Instead of capturing one image per press, the camera keeps shooting, typically at rates ranging from 3 to 30 or more frames per second depending on the camera. This dramatically increases your chances of catching the exact right moment in fast-moving situations.
How Burst Mode Works
When you switch from single-shot to continuous shooting mode, the camera’s shutter, mirror (in DSLRs), and autofocus system operate in a rapid loop. The camera captures each frame, writes it to a memory buffer, and continues shooting. The buffer is a block of fast internal memory that temporarily holds images before they are written to the memory card. Once the buffer fills, the camera slows down or stops until space is freed by writing data to the card.
Buffer depth varies by camera and file format. Shooting JPEG fills the buffer more slowly than RAW because the files are smaller. Some cameras can sustain burst rates indefinitely in JPEG but may only manage 20 to 40 RAW frames before the buffer fills. Using a fast memory card (UHS-II or CFexpress) speeds up the write process and extends the practical burst depth.
When to Use Burst Mode
Sports photography is the classic use case. A basketball player’s expression changes frame to frame, and the ball’s position shifts with each millisecond. Burst mode at 10+ fps lets you select the perfect peak-action frame from dozens of captures.
Wildlife photography relies heavily on burst mode. A bird taking flight, a predator pouncing, or a fish leaping happens in fractions of a second. Without burst mode, timing a single frame perfectly is largely luck.
Children and pets move unpredictably. Burst mode captures a range of expressions and positions so you can pick the best one later. It is also useful for group portraits, where someone always blinks. Shooting three to five frames increases the odds that at least one has everyone’s eyes open.
Practical Considerations
Burst mode generates large numbers of files quickly, so plan your storage accordingly. A 10-second burst at 20 fps produces 200 images, each potentially 25-50 MB in RAW. Use continuous autofocus (AF-C) with burst mode so the camera tracks your subject between frames. Pair burst mode with a fast shutter speed (1/500s or faster for action) to freeze motion within each individual frame.
