|EF-S||Autofocus lens designed only for Canon APS-C digital 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.|
|STM||The lens is equipped with stepping motor to provide smooth, fast and virtually silent autofocus. Learn more|

The lens barrel is of moderate weight, made of plastic. The lens mount is plastic.
The focusing ring is not physically coupled with the focusing mechanism and works electronically (focus-by-wire) - turning of the ring actuates an electric motor that moves the focusing group of the lens to the proper position to achieve sharp focus.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
Full-Time Manual Focus with lenses equipped with stepping or linear motor is performed in the following way - half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the manual focusing ring.
The lens uses front filters with standard size of 58 mm which are easy to find. They are also inexpensive.
It should be noted that most lenses of the system have such diameter of the filter thread, that is why if you will purchase additional lens with similar focal length and/or speed, you probably will be able to share filters between them.
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).
Low dispersion elements (AD, ED, LD, HLD, SD, UD etc) and fluorite elements minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.
The lens features optical image stabilizer, which, according to the manufacturer, compensates up to 3.5 stops of shutter speed. Theoretically it allows to capture sharp images of static subjects at shutter speeds down to 1/22 second at focal length of 250 mm(*).
* without the need to increase ISO sensitivity and/or use a tripod, at the same lighting conditions and at the same aperture
The image stabilizer does not have any specialized mode of operation, but is capable of automatic detection of panning and then corrects camera shake only in one direction.
