IBIS vs Lens Stabilization: What Is the Difference?

Image stabilization can make handheld photography and video easier, but stabilization systems do not all work in the same way. You may see terms such as IBIS, OIS, IS, VR and OSS.

What Is IBIS?

IBIS stands for In-Body Image Stabilization. The stabilization mechanism is built into the camera body and moves the sensor to compensate for certain types of camera movement.

What Is Lens Stabilization?

Lens-based stabilization places the stabilization mechanism inside the lens. Different manufacturers use different names for their optical stabilization systems.

Which Is Better?

There is no universal winner. Effectiveness depends on the specific camera, lens and stabilization implementation. Some cameras have excellent IBIS, some lenses have excellent optical stabilization, and some combinations can work together.

When Does Stabilization Help?

Stabilization is particularly useful when photographing relatively static subjects at slower shutter speeds. It can reduce blur caused by camera movement during handheld shooting.

What Stabilization Cannot Do

Stabilization mainly helps with camera movement. It does not freeze a person running across the frame. Fast-moving subjects can still require a faster shutter speed.

Is Stabilization Important for Video?

It can help reduce small handheld movements, although the result depends on the camera, lens, movement and technique. A gimbal can still be useful for some walking or cinematic shots.

What Should You Check When Buying Used?

If stabilization is important, test it. Check the camera's stabilization function and test a stabilized lens with stabilization enabled and disabled where appropriate. Watch for unusual behaviour or sounds.

Look at the complete camera and lens combination rather than choosing equipment only because it carries an IBIS or stabilization label.
