Canon EF 400mm f / 2.8L IS III USM lens
Combining a preferred super telephoto focal length with a bright f / 2.8 maximum aperture, the EF 400 mm f / 2.8L IS III USM is a L-Series Canonoptic very suitable for outdoor, wildlife and sports applications. This version III of this precious lens features a lighter design along with a sophisticated optical design and updated handling capabilities. The fast maximum opening allows a wide control over the depth of field to isolate subjects with selective focus, and also benefits to work in difficult lighting conditions. Both Super UD and fluorite elements are used in optical design to help reduce color stripes and chromatic aberrations for high clarity and color accuracy, and Super Spectra and Air Sphere Coatings coatings have been applied to elements. individual to suppress flashes and ghost images to increase contrast and color neutrality when working in backlight conditions.
Beyond the optical attributes, this 400 mm f / 2.8 is also characterized by its advanced five-stop image stabilizer system, which has three separate stabilization modes to accommodate various shooting applications. The operation is also complemented by a sophisticated USM ring, which provides fast, quiet and precise autofocus performance along with a full-time manual focus override. A customizable electronic focus ring further contributes to precise manual focus control by providing three levels of focus sensitivity for different applications. In addition, this lens is sealed against the weather for use in difficult environmental conditions, and has a removable rotating tripod collar to benefit work on a tripod or monopod.
Super telephoto prime is designed for Canon full-frame Canon DSLR cameras, however, it can also be used with APS-C models where it provides a focal length equivalent to 640 mm.
The fast maximum f / 2.8 aperture benefits work in low light conditions and also offers significant control over depth of field to work with selective focus techniques.
Super UD and fluorite elements are used to greatly reduce color stripes and chromatic aberrations to achieve greater clarity and color accuracy.
Super Spectra and Air Sphere coatings have been applied to individual elements to control lens flare and phantom effect to obtain greater contrast and color fidelity when working in intense lighting conditions.
An optical image stabilizer helps minimize the appearance of camera shake in up to five shutter speed stops to allow for better work in low light conditions and with slower shutter speeds. Three different IS modes are available: standard single shot mode, an optimized pan mode and a mode that only activates the image stabilizer during exposure.
A ring-type ultrasonic motor (USM) is used, together with optimized focusing algorithms and a high-speed CPU, to deliver fast, accurate and quiet autofocus performance, as well as full-time manual focus override.
The customizable electronic focus ring provides three levels of sensitivity for the speed and accuracy with which the lens can focus manually
The focus preset function is available to quickly recover a programmed focus position.
The rounded nine-leaf diaphragm contributes to a pleasant unfocused quality that benefits from the use of shallow depth of field and selective focus techniques.
As a member of the esteemed L series, this lens is sealed against dust and moisture to work in harsh environmental conditions and also has a fluorine coating on the front and rear elements to protect against water spots, stains or oil residue .
A removable rotating tripod collar is included and it benefits from working with the lens on top of a tripod or monopod.
