IBIS
In-Body Image Stabilization — the camera body itself moves the sensor to counter hand shake. Works with any lens, including unstabilized primes and adapted vintage glass.
IBIS uses a sensor-shift mechanism inside the camera body. Modern systems move the sensor along 5 axes — pitch, yaw, roll, X, and Y — for up to 8 stops of stabilization on the best implementations.
When it matters
- Adapted lenses (which have no stabilization of their own).
- Wide-angle primes.
- Video without a gimbal.
When it doesn't
For long telephoto lenses, lens-based stabilization is usually more effective at the longest focal lengths because the angular displacement at the sensor is too large for a sensor-shift mechanism to fully compensate. Best results come from cameras with both — IBIS + in-lens stabilization working together.
How to use IBIS in a real comparison
In-Body Image Stabilization — the camera body itself moves the sensor to counter hand shake. Works with any lens, including unstabilized primes and adapted vintage glass. In practice, this is most useful as one part of a decision rather than a standalone quality badge. Compare it alongside the workload, room, ecosystem, budget, and ownership constraints that apply to you; the strongest published figure is not automatically the best outcome for every buyer.

Avoid the one-number trap
Manufacturers can describe the same capability under different conditions. Compare like-for-like variants, check the unit and test condition where available, and use a head-to-head page to see whether a measurable difference is material for your own use.
vsMars presents structured catalog values to make trade-offs legible. The linked product and spec pages are the right place to inspect the underlying values before buying.
