OIS in a camera means Optical Image Stabilization. It helps reduce blur from hand shake by physically adjusting parts of the lens or optical path while you shoot.

Quick Scoop

  • What it does: Keeps photos and videos steadier when your hands move a little.
  • How it works: Tiny sensors detect motion, and the camera compensates by shifting lens elements or the optical path.
  • Why it helps: It is especially useful in low light, zoom shots, and video, where even small shakes can cause blur.
