How to Use Burst Mode for Sharper Action Shots

Continuous shooting - burst mode - takes a rapid sequence of frames while the shutter button is held down. Entry-level cameras manage 5-7 frames per second, mid-range bodies 8-12, and sports models 20-30 with the electronic shutter. It exists for one reason: peak action is unpredictable, and a burst raises the odds of catching the moment when a jumper is at the top of their arc or a bird's wings are fully spread.

Burst shooting only helps if the rest of the settings cooperate. First, switch to AF-C (AI Servo) so the camera keeps tracking between frames; a burst in AF-S gives you one sharp frame and a string of soft ones. Second, set a shutter speed fast enough to freeze the subject - 1/500s for running children, 1/1000-1/2000s for sport and birds. Third, choose a wide or zone AF area with subject tracking, otherwise the camera may latch onto the background instead of the runner.

Buffer depth is the usual bottleneck. The camera writes frames into a memory buffer before they reach the card, so a slow SD card makes the burst stutter after a second. A UHS-II card rated 200MB/s or faster clears the buffer far quicker than a budget 45MB/s card. If you need longer bursts, shoot JPEG or a compressed RAW format instead of uncompressed RAW, and turn off in-camera lens corrections and long-exposure noise reduction to reduce file size and processing time.

Resist machine-gunning everything. Short bursts of three to five frames timed to the start of the action give you a manageable edit and a better hit rate than holding the button down for ten seconds. For portraits, the slow 3-5 fps setting is genuinely useful for catching the one natural expression in a stiff pose. Finally, electronic (silent) shutters avoid mirror slap but can show rolling-shutter distortion on fast pans and banding under artificial light, so test them before trusting them indoors.
