How good is your camera image stabiliser?

In simple language, the image stabiliser, whether it is on your lens or on your camera body, prevents camera shake. Camera shake is caused by your shaky hands when hand holding your camera shooting a stationary object like the leopard below as an example at a lower shutter speed. If your shutter speed is high enough, image stabiliser is not effective at all.

Finding at what speed your picture starts to show camera shake is very important. As a rule of thumb, if you use a 100mm lens, the minimum speed that you need to use without camera shake is 1/100 sec or higher. So with 200mm lens, the minimum speed will be 1/200 sec or higher. The table below gives you an idea of the lens you use and the minimum speed needed in order not to cause camera shake.

Your lens (mm)Minimum shutter speed
50 mm1/50 sec
100 mm1/100 sec
200 mm1/200 sec

If you are equipped with an image stabiliser, your minimum shutter speed will be reduced by 2 to 3 stops depending on the specification of the image stabiliser. Newer stabiliser can go up to 5 stops.

Therefore, when the lighting is low and you have to shoot at lower shutter speed on stationary subject image stabiliser is a great asset when you want to maintain your low ISO to keep the ISO noise under control.
