Canon EF 100-400mm f/4.5-5.6 L IS (IMAGE STABILIZER) USM Lens - for Canon DSLR Cameras

Canon EF 100-400mm f/4.5-5.6 L IS 

(IMAGE STABILIZER) USM lens 

The Canon EF 100-400mm f/4.5-5.6L IS USM Lens has an excellent focal length range that includes the longest focal length found in a Canon zoom lens - 400mm. This long focal length and focal length range combine with very good image and build quality to make the 100-400 L one of the most popular serious wildlife and sports lenses Canon sells.

To say that the Canon EF 100-400mm f/4.5-5.6L IS USM Lens is a member of the  quickly says a lot about this lens. Weighing 3 lb (1,380g) and measuring 3.6" x 7.4" (92.0 x 189.0) (DxL retracted), the 100-400 is solidly built and feels like it.

The push/pull zoom mechanism is possibly the most noticeable physical feature of this lens. While it works smoothly, it took me some time to get used to it. There is a ring on the back of the manual focus ring that adjusts the tension on the zoom part of the lens. That is a nice feature, but I find myself constantly adjusting the tension to get it just right for the moment. The ring also gets in the way of the manual focus ring - when making a manual focus adjustment, I often inadvertently change the zoom friction ring as well. Set the zoom friction too light and the lens extends by itself when pointed downward - fast and hard if set really loose. Set the friction too tight and zooming becomes difficult. So, it works as it is supposed to. A big benefit to the push/pull design is that your supporting hand remains centered under the lens at all times. Some photographers prefer the push/pull design.
