A long-reaching telephoto zoom characterized by a sophisticated optical design and advanced image stabilization technologies, the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens is part of the esteemed L-series developed for full-frame EOS DSLRs. One fluorite element and one Super UD element have been incorporated into the lens' construction, and both help to reduce aberrations and distortions throughout the zoom range in order to deliver notable clarity, image sharpness, and faithful color reproduction. An Air Sphere Coating has also been applied to lens elements in order to reduce lens flare and ghosting for more contrast-rich imagery. Benefitting the optical components of the lens, a four-stop effective Image Stabilizer helps to minimize the appearance of camera shake and can be dedicated to different styles of shooting. Furthermore, a redeveloped rotation-type zoom ring pairs with an internal focusing mechanism, and an Ultrasonic Motor, to deliver quick and intuitive handling to benefit handheld shooting. Positioned as a versatile option for sports and wildlife photographers, this lens' list of attributes make it a viable telephoto zoom for a variety of shooting applications.

Housed within a weather-resistant barrel, this lens also features fluorine coatings on the front and rear elements for protection against fingerprints and smudges from affecting image quality. Zoom control is complemented by a dedicated tension ring for adjusting zoom torque. Additionally, other refined design elements include a tripod collar that can be attached or detached with the lens mounted to the camera and an included lens hood that permits easy control over specialty filters with the hood in place.

Telephoto zoom is compatible with full-frame EF-mount DSLRs, as well as APS-C-format models where it provides a 160-640mm equivalent focal length range.

One fluorite element and one Super Ultra-Low Dispersion element help to correct chromatic aberrations throughout the zoom range for a high degree of sharpness, clarity, and color accuracy.

An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.

An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Additionally, three dedicated image stabilization modes are available—Standard, Panning, and During Exposure Only—and can be selectively employed to suit a variety of types of shooting.

A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.

The rotation-type zoom ring offers precise adjustment between zoom positions, especially when shooting handheld, and a zoom torque adjustment ring enables easy setting of the zoom tension for personalized control.

A weather-resistant design protects the lens from dust and moisture to enable its use in inclement conditions. Additionally, fluorine coatings have also been applied to the front and rear lens elements for further protection against fingerprints and smudging.

Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.

A redeveloped tripod collar can be attached or detached from the lens without having to remove the lens from the camera.

The included ET-83D lens hood incorporates a side window for easier adjustment of rotating filters with the hood in place.

A: Sigma makes a really good lens, as I have four of them but I also have the EF 28-135mm and it is a great lens and for the price you should go ahead and get it you can't go wrong. It is a very sharp and practical lens, great as a walk around and I can only assume that for that price, Canon will be discontinuing that lens...why I don't know.

Q: 9. how much of an upgrade is this over the 18-55mm lens i recieved with my camera? im either getting this or the travel package by canon. if i get this i will also buy the 50mm prime.

A: If you received an 18-55mm with your camera, then it means your camera is a crop sensor camera. In that kit lens, you range from wide angle to short tele. If you purchase this lens, you will be losing wide angle. 28mm on a crop sensor will give you close to a normal angle of view. But what you lose in wide, you gain in tele. That 135mm on the tele end will give you a lot more magnification of things in the distance. Build quality is much better on this lens and if you ever decide to go with a full frame camera in the future, this lens will work with it as will the 50mm prime. The 18-55mm would be rendered useless on a full frame.

Q: 10. Will this fit canon 6d mark ii
