Image Stabilizationequipment
Tech (in lens or body) that counteracts hand shake so you can shoot slower handheld.
Stabilization (lens IS/VR/OSS or in-body IBIS) buys you several stops of slower shutter without blur from your own movement. It does NOT freeze a moving subject — only camera shake. For action you still need a fast shutter.
Use this when
- Low light handheld, still subjects: turn IS on
- On a tripod: often turn it off
Common mistake: Relying on IS to freeze a moving subject — it won't.
