…so what is the deal with image stabilization/vibration reduction (IS/VR), if your lens or camera has it?
- Use it! It is a great feature: it adds several stops to your ability to take low shutter speed.
- If your camera is on a tripod, do not use it. It does not good and may do harm (like wearing our your battery).
- If you are shaking wildly because you are following something, do not use it.
- If you are tracking a subject that moves in a linear direction, like yesterday’s aircraft, use it – if you have a “mode 1/mode 2” or “active/passive” switch, which you have on high-end lenses. Mode 2/Active means “I am tracking something on one direction, so only stabilise in the direction perpendicular to my tracking”.
On Nikon and Canon, you have VR/IS in the lens. Sony does it in the body: cheaper, but less optimized to the lens length, and you can’t see the effect.
