Canon EF-S 55-200mm IS now with STM

Canon EF-S 55-250mm f4-5.6 IS STM

In addition to the number of new compact cameras, Canon have also announced an improved version of the EF-S 55-200mm f/4-5.6 IS which sports the STM stepper motor. Contrary to what seems to be a growing popular belief, STM lenses are not meant to increase the speed of autofocus in live-view and video mode as much as it is to cut out the noise of the focusing motor being picked up by the audio on your camera. It also aims to be a much smoother focusing system which in video is rather important.
