Canon 100-400mm Lens

The Canon EF 100-400mm Lens is a favorite of many photographers. It is quite versatile because of the zoom range between 100mm and 400mm. It is a super Canon zoom lens for wildlife and sports action, but it is also a great portrait lens.

When attached to a Canon digital SLR with an APS-C sensor, it is equivalent to 160mm-680mm, so it is plenty long for those bird photos or at the zoo when the fence keeps you away from the animals. Add to that the excellent compatibility with a Canon 1.4 or 2.0 Extender and the focal length goes even higher.

Aperture is f/4.5-5.6 which means that it will not be the fastest lens in low light situations, but users have accepted that and adapted to it. The IS (image stabilization) does compensate for that somewhat, but the main advantage of IS is being able to handhold the camera in normal shooting situations and not needing to rely on a tripod.

This is an L-series lens which is Canon’s very best series. Materials and workmanship in the Canon 100-400mm lens is top-notch, as it is with all L-series lenses. Amazon Customer Rating for the Canon 100-400mm lens is 4.7 Stars.

If you are not familiar with a push-pull type zoom lens, it will take about 2 minutes to get used to. This is the normal statement from new users. They were mostly apprehensive about this type of zoom lens, but they quickly got accustomed to it and never had a problem with it.

One user comment at Amazon starts off like this: “First, I just want to say… I waited most of my life to get to the point where I could take professional quality pictures. Now that I am there, it is indeed everything I wanted it to be. I’m loving this. :-)

This is really quite typical. In spite of all the praise (you can see from the graphic at the top of the page that most ratings are either 5 or 4 stars), nearly all users mentioned the size and bulk of the Canon 100-400mm lens. It is obviously impressive.
