Canon 70-200mm f4 L II IS USM lens

With a compact and lightweight design with updated stabilization and performance, Canon 's EF 70-200mm f/4L IS II USM is an impressively versatile telephoto zoom. Well suited for a wide range of subjects, from events to portraits to sports, this zoom is characterized by its constant f/4 maximum aperture to strike a balance between consistent performance and portability. Its optical design includes a pair of UD elements and a fluorite element to greatly reduce chromatic aberrations and color fringes. This streamlined design, along with a Super Spectra coating, also helps control reflections and ghosting for greater contrast and color accuracy when working in tense, backlit light conditions.
Version II of this popular lens also includes the inclusion of a revised Optical Image Stabilizer, which now compensates for five stops of camera shake and offers three distinct stabilization modes to suit different shooting applications. A ring-type USM and internal focusing mechanism also offer quiet, accurate autofocus, as well as full-time manual focus override. In addition, this lens is weather-sealed for use in harsh environmental conditions.

• The versatile zoom is designed for full-frame EF mount DSLR Canon , however it can also be used with APS-C models where it provides an equivalent focal length range of 112-320mm.
• The constant maximum aperture of f/4 delivers consistent performance throughout the zoom range and also contributes to the relatively lightweight design and compact format.
• One fluorite element and two ultra-low dispersion glass elements significantly reduce color stripes and chromatic aberrations for greater 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 bright lighting conditions.
• An optical image stabilizer helps minimize the appearance of camera shake by up to five stops of shutter speed to enable better work in low-light conditions and with slower shutter speeds. In addition, three dedicated image stabilization modes are available: Standard, Exposure Only, and Panorama, and they can be selectively employed to suit a variety of shooting types.
• A ring-type ultrasonic motor (USM), along with an internal focusing system, is employed to deliver fast, accurate and quiet autofocus performance, as well as full-time manual focus override.
• The Focus Limiter switch allows you to restrict focus to two different ranges to suit different applications: 3.3'-infinity or 9.8'-infinity.
• The rounded nine-blade diaphragm contributes to a pleasant out-of-focus quality that benefits the use of shallow depth of field and selective focusing techniques.
• As a member of the esteemed L-series, this lens is sealed against dust and moisture to work in inclement environmental conditions.
