Image Stabilization for sharp images

Category:Uncategorized Tags : 

It is an technology that enable you to capture under lighting conditions so, there is possibility for you to get sharp images. Depending on the make, model, and vintage of your IS-enabled camera or lens, image stabilization allows you to capture sharp pictures at shutter speeds three, four, or five times slower than previously possible.

Lens-based stabilization uses a floating lens element, which is electronically controlled and shifted opposite to any camera shake recorded by the camera.

The worst misconception about stabilization that you can “freeze” fast-moving objects at slower shutter speeds if you have stabilization.

Actually, it only gives you opportunity to take sharp images of static subjects at slower speed. Moving objects will be equally blurry or streaky—and in some cases blurrier or shakier with the IS turned on.

The most important rule for capturing sharp is you shouldn’t handhold a camera at shutter speeds slower than the equivalent focal length of the lens. This means a 500mm lens shouldn’t be handheld at speeds slower than 1/500-second, a 300mm lens slower than 1/300-second, a 50mm lens slower than 1/50-second, and a 20mm lens slower than 1/20-second.

Add image stabilization into the mix and suddenly you can capture sharp images of still objects with a 500mm lens at speeds down to 1/60-second, a 300mm lens at speeds down to 1/30-second, and a 20mm lens at speeds down to 1/2-second.

There are two types of image stabilization (IS): lens based and in camera. In this article, we are only talking about lens based. For deep understanding about stabilization in camera, you can check through this link.

Manufacturers have different name for this function :

  • Nikon – VR
  • Canon – IS
  • Pentax – Image stabilization in the cameras
  • Sony – Image stabilization in the cameras
  • Sigma – OS
  • Tamron – VC

The advantages of in-lens image stabilization include smoother performance when using longer focal length lenses. The downside of lens-based image stabilization is that it’s not available as an option for all lenses and it adds to the cost of the lens. Then again, if you don’t need IS, you often have the option of purchasing a non-IS version of the lens, or at least something similar.

You must keep your tripod away from you when you use image stabilization because if you use it and tripod together so, you will get counterproductive and creating a feedback loop. Here, the camera detects its own vibrations. It will start moving to counteract them, even when the camera is completely still.

And last, you must remember to should turn off your stabilization system is battery life. Having it on, especially when you aren’t using it, will eat up your battery like cake at a kids party. This is especially true of larger lenses and larger sensors. Moving them around requires more energy.
