Photographers looking for the perfect wildlife, nature and sports photography lens often end their search at the Canon 300mm f/4 “L series” telephoto lens. This lens incorporates the highest quality Canon “L series” glass in a relatively light (considering the focal length) and comparatively less expensive package.
Images from the 300mm f/4 are sharp and full of contrast. Performance at f/5.6 and f/8 is matchless with lenses of similar focal lengths.The lens also makes excellent use of Canon’s latest image stabilization technology, utilizing two modes of image stabilization designed to add an extra dimension of ease to action based photography. The first image stabilizing mode works in the traditional manor, as it does with all other Canon lenses. The second mode automatically detects when the photographer is panning the camera horizontally or vertically and adjusts to create a shake-free image when the shutter release is pressed.
The 300mm f/4 has a very fast auto focus and a high level build quality. Moreover, Canon includes a retractable lens hood on this lens.

What Users Like About This Lens
Photographers praise the feel and weight of the 300mm f/4 “L series” lens. Considering the lens’ focal length, it is a very easy to carry piece of equipment. Users have noticed that even on full-frame digital SLR bodies, the lens performs flawlessly, delivering full frame to frame sharpness at f/5.6 and f/8.
Additionally, at these apertures, the lens is unbeatable (in the minds of many) by any other 300mm lens. Compared to lenses that produce similar results, the 300mm f/4 is less expensive. The retractable lens hood is very functional and favored as well as the superior build quality of the lens.
What Users Don’t Like About This Lens
One problem with the 300mm f/4 is that it is not weather sealed. While the build quality is exceptional, dust and water will destroy the lens if it is used in harsh conditions. While image quality is perfect at f/5.6 and above, at f/4 some vignetting occurs on the outside edges of images when a full frame digital SLR body is used. Finally, some photographers feel that the 300mm f/4 is not as good as the older 300mm f/2.8 model.
These users mostly miss the extra exposure latitude offered by a higher maximum aperture. A reduction of the maximum aperture allows the f/4 model to be lighter and easier to carry. Image stabilization also helps make up for the larger maximum aperture.
