- EF-Mount Lens/Full-Frame Format
- Aperture Range: f/4 to f/45

- Versatile telephoto zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 112-480mm equivalent focal length range.
- One ultra-low dispersion glass element reduces color fringing and chromatic aberrations for high clarity and color fidelity.
- Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
- An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to three shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. In addition to the single-shot standard IS mode, a second mode is also available that is optimized for panning.
- A micro Ultrasonic Motor (USM) is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
- Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
- Zoom lock switch can be used to keep the lens at the 70mm focal length position in order to maintain its most compact dimension when not in use.
