|EF||Autofocus lens designed both for Canon full frame and APS-C SLR cameras.|
|IS||The lens is equipped with optical image stabilizer. The stabilizer allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without stabilizer you will have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.|
|DO||The lens incorporates DO elements which cancel chromatic aberrations at various wavelengths. This technology results in smaller and lighter lenses in comparison with traditional designs with no compromise in image quality.|
|USM||The lens is equipped with ultrasonic motor to provide very fast and virtually silent autofocus. Learn more|

Design and Features
The lens barrel is heavy, made of plastic. The lens mount is metallic.
The lens features a zoom lock lever to keep the zoom ring fixed at the shortest focal length of 70 mm. This function is convenient for carrying a camera with the lens on a strap because it prevents the lens from extending.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
The lens uses front filters with standard size of 58 mm which are easy to find. They are also inexpensive.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
The lens features optical image stabilizer, which, according to the manufacturer, compensates up to 3 stops of shutter speed. Theoretically it allows to capture sharp images of static subjects at shutter speeds down to 1/37 second at focal length of 300 mm*).
*) without the need to increase ISO sensitivity and/or use a tripod, at the same lighting conditions and at the same aperture
At the choice of the photographer the image stabilizer can operate in one of the following modes:
|Mode 1||Corrects vertical and horizontal camera shake. Mainly effective for shooting still subjects.|
|Mode 2||Corrects vertical camera shake during following shots in a horizontal direction. Corrects horizontal camera shake during following shots in a vertical direction.|
|Camera:||Canon EOS 5D mark II|
