The Canon 400mm f/4L DO IS II USM

The Canon 400mm f/4L DO IS II is a supertelephoto lens for Canon DSLRs and update to the Canon 400mm f/4L DO IS. Key features include:

Diffractive Optics. Gapless dual-layer diffractive optics allow the lens to be smaller and lighter compared to traditional Canon supertelephoto lenses. This advanced optic system reduces chromatic and spherical aberrations, ensuring high-quality images.

Supertelephoto Focal Length. The 400mm focal length is popular for sports and wildlife photographers, with this lens targeting the latter of the two with its reduced size and weight.

Image Stabilization. The in-lens stabilizer provides up to four stops of correction to combat image shake. There are three modes to choose from (Standard, Panning, and During Exposure Only) depending on your needs, and automatic tripod detection means you don’t have to turn it off when locked down on a tripod.

Ultrasonic AF Motor. Along with an internal focus design, this provides fast, silent autofocus performance. It has full-time manual-focus override, a focus-limit switch and stop buttons for preventing focus hunting, and a Power Focus Mode for pseudo-follow-focus movements.

Build & Optics. Its weather-resistant build lets you keep shooting when the weather gets questionable, with fluorine coated front and rear elements keeping them free of water and smudges. Besides the diffractive optics system, the 400mm f/4 DO IS II also features one large-diameter ground aspherical element and one Ultra Low Dispersion element to improve overall image quality. The integrated tripod foot allows easy attachment to a tripod or monopod, and the included Drop-in UV filter takes care of ultraviolet light.

If you don't see exactly what you're looking for and that makes you sad, please give us a shout. We might have good news for you. Here's a link to our contact form.

We offer a 3-day inspection period on all sales, during which time you may return the item for a refund of the purchase price, not including shipping.

On this item, we include a LensAuthority 90-day limited warranty. This warranty covers damage that arises from normal use of the item. It does NOT cover accidental or intentional damage. More details are available in our FAQ section.

In addition to the standard 90-day warranty, you may have the option to purchase an extended warranty. If we're able to offer an extended warranty on this item, you'll see a checkbox to add that warranty - see the area just above the "Add to Cart" button.

If you select the extended warranty, you'll get additional protection from Consumer Priority Service ("CPS"). The CPS warranty will take effect after our 90-day warranty ends. However, the CPS warranty term would begin on the date of purchase. For example, if you buy an item with a 2-year extended warranty today, your coverage would end two years from today.
