Technique Tuesday – Canon EF 200-400mm f/4L IS USM


For the last post on lenses we focused on the super wide angle, and how it affects perspective. Now I am introducing my favorite zoom lens for photographing wildlife, the 200-400mm. It has an internal 1.4 extender which is absolutely fantastic. It pushes the 400mm to 560mm and opens the aperture to get more light to the sensor.

I have been known to add an additional external 1.4 or 2 extender on top of this. This is recommended only in desperate situations, like when the snow leopards are spotted two miles across a Himalayan valley and you are on foot. Not only does the extender restrict light to the sensor, it magnifies the faults of the lens.

I use this lens for more than wildlife, though. Strong telephoto focal lengths are needed for photographing extreme compression effects, such as pulling in background elements like the setting sun to make them tower over the foreground subjects.

In addition, the telephoto allows you to:

  • cut down the angle of view and isolate aspects of the scene in front of you
  • get close to wildlife without disturbing it
  • frame simple compositions–look for little slices of design and interest within a landscape

Last and very important – to use this heavy lens effectively, you’ll need a sturdy tripod and a strong back as it weighs nearly 8 pounds.
