Fans of the Canon EOS 24 by 70 mm IS USM lenses may want to consider two recently released lenses in the same class. The 24 by 105 mm and 70 by 300 mm IS USM lenses provide a panoply of options for professionals or advanced amateurs. These lenses are ideal for complementing the Canon's newly released EOS 5-D model.

IS--otherwise known as image stabilization--technology allows camera users to make subtle adjustments without losing image detail. Inside the lens, special gyroscopes ensure the ultimate stability of the camera by negating the impact of subtle hand shakes. You no longer need to set up your camera on a tripod and wait for the wind to die down to get extremely clear shots.

The way the IS sensor works is that it actually changes the path of the light coming into the camera, so that the sensor plane grabs the image that you want. It also incorporates technology to allow the shutter speed to slow down without revealing any shaking. You can employ the aforementioned lenses to grab beautiful images, even in particularly low light situations.

Another advantage is the USM motor, which dampens sound and vibrations, thus ensuring that they won't tamper with image quality. The IS lens prevents overshooting and over focusing by using precision algorithms to tailor shots. In addition, you can also switch easily into a manual mode without having to leave the autofocus mode.
