There’s a shot you know you need to take, but there’s just one problem—it’s far away, and the subject (like wildlife) is uncertain to stay. Whether you’re on a safari taking a picture of a stunning gazelle or on a North American nature trip spotting a Bald Eagle, the problem is clear: you need a high-capacity zoom lens that won’t blur and shake like the other lenses. Meet the CANON EF 100-400mm 4.5/5.6L USM IS II USA, a lens capable of doing all that and more. Like many zoom lenses at Adorama, this lens is great for wildlife shots and active photography—but we think you’ll find that as you read more and more about this lens, it’s capable of doing just about anything you can demand from it.

  • Serious zoom capacity is always a necessity when working at this level of lens, and the Canon EF 100-400mm has exactly that, thanks to 21 elements in 16 groups in the construction of the lens. As a 100-400mm f/4.5-5.6 zoom lens, it has some serious zooming-in abilities, taking far-off shots with a surprising amount of depth and clarity. If you need a stunning shot right now and it can’t wait, you’ll need a lens capable of zooming in and keeping up with you every step of the way.
  • Serious image stabilization is needed when you have serious zoom levels, as well. That means you’ll need exactly what Canon EF 100-400mm can provide, which is an Optical Image Stabilizer that provides correction of up to four shutter speed steps. This helps reduce the blurring and aberrations that occur with non-stabilized lenses, and helps ensure that even those far-off shots end up coming out smooth and sharp, as though you were right next to your subject all along.
  • Have we mentioned the aperture? Sure, we’ve mentioned the Canon EF 100-400mm’s focal length, but the aperture really grabs light in a unique way, thanks to a circular design of 9 blades that delivers stunning and soft backgrounds. This makes your shots subtle and, though you can tell any zoom shot is a zoom shot, takes the emphasis off the fact that you were far away from your subject and places it the emphasis right back on the subject itself.
  • When you’re dealing with zooming, you also need to ensure that there are no smudges—even the smallest detail can ruin a perfectly good shot. That’s why no stone is left unturned with the Canon EF 100-400mm. It’s highly resistant to both water and dust, it features a New Air Sphere Coating (ASC) that helps to reduce the “ghosting” you see with the cheapo lenses, and you can work with specialty filters even with the lens hood in place, offering an additional layer of protection.
  • Oh, focusing distance. You wanted to hear about that, right? After all, it isa zoom lens: with a minimum focusing distance of 3.2 feet, you know that while you have the goods here to take some serious far-off shots with crispness and clarity, you can get the same from a subject located much closer in.


It takes a lot to construct a zoom lens—just ask NASA—but it doesn’t always mean you need to have a space agency-sized budget to take spectacular zoom photos. Procure a CANON EF 100-400mm 4.5/5.6L USM IS II USA of your very own here at Adorama and you’ll be on your way to professional-grade photography.
