Canon EF-S 55-250mm f/4-5.6 IS STM Lens
Designed for use in Canon's APS-sensor based DSLRs, the new Canon EF 55-250mm f/4-5.6 IS STM telephoto zoom lens boasts especially quiet zoom operation, making it the sixth STM lens in the Canon line. STM lenses use the same Stepping Motor, which is virtually silent and is therefore best suited for video capture. (A DSLR's on-camera mic will pick up zoom sounds, which is why we generally recommend using an off-camera microphone.)
The new 55-250mm lens is a consumer-grade lens with one UD element that Canon says will reduce chromatic aberration, a 7-blade circular aperture, and focusing as close as 2.79 feet.
