Construction

The EF 400mm f/2.8L IS III USM lens is comprised of 17 lens elements in 13 groups. A Super UD (ultra-low dispersion) element offers improved image quality by greatly reducing color fringing and chromatic aberrations. Super Spectra Coating (SSC) and Air Sphere Coatings (ASC) minimize ghosting and flare. Optical placement of the lens construction has been improved to bring the center of gravity closer to the rear. This allows for you to position your lens more easily for fast framing. Increased Heat Shielding reduces the thermal effects on the lens to maintain quality throughout the life of the lens.

Image Stabilization

The Canon EF 400mm f/2.8L IS III USM lens features a dynamic 5.0-stop optical image stabilization system with 3 distinct IS modes to help you find the perfect image every time. Standard single-shot mode gives you simply perfect still images. Panning-optimized mode gives you blur-free images across a scene. A third IS mode only activates when you are using the exposure. Shake reduction for up to 5 shutter speed stops helps provide reliable handheld performance and clear image detail in low-light situations or at lower ISOs.

Control Ring

A customizable electronic manual focusing ring ensures you get just the right shot at just the right moment. You can precisely and quickly adjust the focus with three sensitivity levels. You can fine-tune your focus manually even when autofocus is in use.

Durability

The EF 400mm lens was built for excellent performance in the toughest of conditions. This lens was built with a magnesium and titanium construction for a durable and lighter weight design. Fluorine coating was placed along the barrel to keep soiling, smears and fingerprints to a minimum. The EF 400mm f/2.8L IS III USM Lens is dust and water resistant to protect against difficult weather conditions.
