Canon EF 300mm f / 2.8L IS II USM lens
Versatile due to its medium telephoto focal length and its bright maximum aperture, the Canon EF 300 mm f / 2.8L IS II USM is also distinguished by its high speed performance and intuitive operation to adapt to its use in a wide variety of conditions of work. As an L-series lens, this telephoto lens, of course, has an advanced optical design; Two fluorite elements are used to reduce color stripes and chromatic aberrations for greater clarity and color accuracy, and a secondary wavelength coating has been applied to individual elements to suppress flashes and ghost images to increase contrast and color neutrality when working in backlight conditions. The rapid maximum aperture of f / 2.8 also allows extensive control over depth of field to isolate subjects using selective focus, and also benefits from working in difficult lighting conditions.
Beyond the optical design, this 300mm f / 2.8 is also characterized by its effective four-stop image stabilizer system, which has three separate stabilization modes to accommodate various shooting applications. In addition, the handling is a sophisticated USM ring, which provides fast, quiet and precise autofocus performance along with a full-time manual focus override. 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 an equivalent focal length of 480 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.
Two fluorite elements are used to greatly reduce color stripes and chromatic aberrations to achieve greater clarity and color accuracy.
A secondary wavelength coating has been applied to individual elements to control the lens flare and the 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 at up to four 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, along 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 focus preset function is available to quickly recover a programmed focus position.
The focus limiter switch allows you to restrict the focus to three different ranges to suit different applications.
A Power Focus setting is available, and allows you to adjust your focus position electronically and smoothly to fit the video recording. This setting uses a dedicated ring in front of the main focus ring and allows you to use one of two different focus speeds.
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 inclement environmental conditions.
A removable rotating tripod collar is included and it benefits from working with the lens on top of a tripod or monopod.
Compatible with optional EF 1.4X and EF 2X teleconverters.
