The Sigma 300-800mm f/5.6 DG HSM for Canon

The Sigma 300-800mm f/5.6 EX DG APO HSM is a large super-telephoto zoom lens designed for Canon full-frame cameras. Key features include:

Large Supertele Zoom Range. The 300-800 f/5.6 Sigma lens provides an obviously unique zoom range. It’s quite a sharp lens but perhaps not the quickest focusing lens you’ve shot with, so it's more appropriate for larger wildlife and perched birds. Birds in flight will be more of a challenge.

Constant f/5.6 Aperture. While many zoom lenses offer a constant aperture throughout their zoom range, this one is a bit different. To do so in a lens with this large a zoom range is just impressive.

You’re Gonna Want a Tripod. At almost 13 lbs. and 21" long, this is a heavy lens, and it’s not image stabilized. It requires very stable support (a heavy duty tripod and gimbal head) and excellent long-lens technique. Best images will be obtained with a remote shutter-release and mirror lock-up. We’ve tested it carefully, but even in the shop soft images have been 100% because of user error – it requires excellent technique and some practice.

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.
