Canon EF 600mm f/4L IS USM






This lens is ideal for sports and wildlife photography. The newly designed optical system has one fluorite element and two UD-glass elements to obtain high resolution and high contrast. Also, the minimum focusing distance was reduced to 18 ft. (5.5m). Extender EF 2x II can be attached to increase the focal length to 1200mm while retaining AF (at the center focusing point with the EOS-1v and EOS-3).

An outstanding professional lens for bridging distances in sports, wildlife, and many other applications--including commercial and fashion for the distinct "compressed" telephoto character and totally out-of-focus backgrounds its images can possess. Fluorite and UDglass are combined for incredible image quality, even wide-open. Image Stabilization adds a new dimension in this long lens’ usefulness, even in marginal lighting. It works beautifully with both 1.4x II and 2x II extenders, and now focuses as close as 17.5 feet/5.4 m. It has the same weather-resistant gaskets and sealed focusing and focus pre-set rings as Canon’s other Image Stabilized super-telephoto lenses.

A super telephoto lens can make an ordinary scene into an extraordinary one. Its ability to see surpasses that of the human eye. It can compress images and make them look as if they come from another dimension. It opens up new realms of photographic expression. All EF super telephoto lenses are L-series lenses to provide the highest quality. The USM provides quiet and high-speed autofocusing. These lenses promise outstanding delineation and put your imagination to the test.

The Digital Picture.com Says:

Canon has made an effort to keep the Canon EF 600mm f/4.0 L IS USM Lens as light as possible without sacrificing strength by utilizing a Magnesium alloy lens barrel. The carbon fiber lens hood is very light (and very expensive to replace). You will want to use it for protection and improved contrast. I should note that Canon uses a protective front lens element in the 600 IS.

Canon Website Customer Review:
I have used this lens for wild life and it is very hard to take a bad shot with this lens. The IQ and size are royal. It is built like a tank (including size). It is pretty fast at AF of fast moving subjects. You need to plan ahead your shooting, since it is a heavy lens. Used with a 1.4TCON along a crop body and you have some reach.

Increditable images. Forget the 600mm's, the images from this lens are very impressive, better than my other two Canon L lens - the f/2.8, 28-70mm zoom and the f/4, 300mm.
Before getting this lens in my hands, I thought I would be able to handhold shots using image stabilization. While this is possible, to get the full use from this lens a high quality tripod with Wimberley Mount is really a requirement. I have found this lens is really just too big to reasonably handheld. So unless you know a machinist, expect to spend another $1400. This adds not only to the price, but also to the equipment that you will need to carry to your shooting location, which brings up my next point.
In my research before getting this lens, numerous writers were complaining about carrying this lens to location. In my personal experience (I'm a 62-year-old retiree) I have not found this to be a problem. Yes it is heavy, but easily carried by the handle or inside a Lowes backpack if going a greater distance.
It should be noted that once you have all this equipment carried to a location, you are pretty much restricted to just taking pictures with your 600mm lens. Carrying this lens is a full time job requiring all your attention.
And taking about attention, you will attract a lot of it. Everyone, yes everyone will take notice of you, which as far as I am concerned is never a good thing, especially if you find yourself isolated along with some bad guys who realize the value of the equipment you are carrying.
