Digital camera reviews of Canon EF 100-400mm f4.5-5.6L IS USM Telephoto Zoom Lens for Canon SLR Cameras

Digital camera Review: Great lens -- especially for sports and safari
Summary: 5 Stars

Bought this lens to take on safari and to use with sports. Works great for both. I especially appreciate it's ability to cover the complete range of 100 to 400 without a lens change.

I'm sure primes may be sharper at a given focal length, but we weren't in a position to buy or carry that many prime lenses.

But this lens.

Digital camera Review: Canon 100-400mm telephoto lens.
Summary: 5 Stars

I upgraded to this I series lens from a Tamron 200-500 telephoto lens and I am very happy that I did.The image quality is noticeably clearer especially at 800mm. (I'm using a Canon 2x extender). It's heavy but you'll be using a tripod anyway. Hey, it's a Canon!

Digital camera Review: Canon EF 100-400 MM F 4.5-5.6 IS USM Zoom Lens
Summary: 5 Stars

As an amateur nature photographer I wanted to purchase a lens that would let me get closer to my subjects, (affectionality referred to as critters), without disturbing them, while, feeding, flying, or playing. This lens really delivers great results. My bird in flight shots are crisp and clear. The details that I now obtain are vivid and it has enabled me to finally achieve the nature photos that I wanted without spending thousands of dollars.
I would highly recommend this lens to nature or wildlife photographers.

Digital camera Review: Very good lens
Summary: 5 Stars

Got great pics with this lens. Took it out for a one week safari earlier this month and the pics were the best I have ever taken. One minor complaint -- wish it has a lock, as it so big and heavy, that without a lens lock, it sometimes can slide out unexpectedly.

Digital camera Review: Canon 100-400mm f/5.6 IS L Lens
Summary: 4 Stars

This lens is great for nature and bird photography as long as you have suitable lighting conditions. It's at its best in soft natural light (overcast days), and performs very well in bright sunlight. Tough to get decent shots in low light with moving subjects. Fine for static subjects in low light. Not recommended for use with a 2x teleconverter unless you have a pro camera body (such as a 1Ds MK II) because you will have to focus manually. Works better with a 1.4x converter for greater reach of far away subjects with a 50D type body. Since it's a telephoto, it is not quite as sharp at each end of the focal range, but I find 200-300mm works extremely well. This lens is not extremely heavy, but it does get tiresome to handhold after about 30-40 minutes, at least for me, so a tripod or monopod is highly recommended as a stable support for the best images if your arms are weak and you will be shooting for more than an hour. I use mine on a Wimberley Head and Gitzo Systematic tripod. The zoom feature is a push-pull style that takes some getting used to, and I find it a bit cumbersome. In order to change focal lengths you have to loosen and tighten the zoom ring tension, or set it just so, and I find it a challenge to keep a specific tension without accidentally tightening or loosening the ring while hand-holding and gripping the lens barrel for support. The IS feature works well for hand-held shots. For birds and wildlife, this is an all-around good starter L-series lens. If I had more money to spend, I would have gone for the 300mm f/2.8 IS or 400mm f/2.8 IS however.
