• Aperture Range: f/2.8 to f/32
• Super UD and Fluorite Elements
• Super Spectra and Air Sphere Coatings
• Ring-Type Ultrasonic Motor AF System
• Customizable Electronic Focusing Ring
• Optical Image Stabilizer

The wide aperture provides precise control over depth of field, allowing for selective focus and improved performance in challenging lighting situations. This lens incorporates Super UD and fluorite elements to minimize chromatic aberrations and color fringing, and utilizes Super Spectra and Air Sphere Coatings on specific components to effectively reduce flare and ghosting for sharper, more accurate images even in backlight situations.

In addition to its optical features, this 400mm f/2.8 lens boasts an advanced five-stop effective Image Stabilizer system that offers three different modes suitable for various types of shooting. To enhance handling, it also includes a sophisticated ring-type USM for fast, quiet, and precise autofocus capabilities with the option for manual focus override. The customizable electronic focusing ring allows for three levels of sensitivity to achieve precise manual focus control in different scenarios. Furthermore, this lens is designed to withstand challenging environmental conditions, and it even includes a detachable rotating collar for easy use on a tripod or monopod.

• Super telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 640mm equivalent focal length.
• Fast f/2.8 maximum aperture benefits working in low-light conditions and also affords significant control over depth of field for working with selective focus techniques.
• Super UD and fluorite elements are used to greatly reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.
• Super Spectra and Air Sphere Coatings have been applied to individual elements to control lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
• An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to five shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure.
• 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.
• Customizable electronic focusing ring provides three sensitivity levels for how quickly and precisely the lens can manually focus.
• Focus Preset function is available to quickly recall a programmed focusing position.
• 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.
• As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions and also features a fluorine coating on the front and rear elements to guard against water spots, smudges, or oil residue.
• Removable rotating tripod collar is included and benefits working with the lens atop a tripod or monopod.
• Compatible with optional EF 1.4X and EF 2X teleconverters.
