The Canon EF 500mm f/4.0 L IS USM Lens is considered a Super Telephoto Lens.
And super it is!
A super long focal length is the biggest attraction to the Canon EF 500mm f/4.0 L IS USM Lens and where the product category gets its title.
Super image quality and sharpness are highly notable features.
Super size might be a downside, but the size is unavoidable in a lens with the Canon EF 500mm f/4.0 L IS USM Lens' specifications.
A super high price is not welcomed by most.
The Canon EF 500mm f/4.0 L IS USM Lens focuses very fast, very accurately - and quietly.
Ring USM (Ultrasonic Motor) is employed and FTM (Full Time manual focus) is enabled.
A 3-position focus limiter switch allows focusing distances to be limited to a
specific distance range - or to be unlimited (4.5m to 10m, 10m to infinity, 4.5m to infinity).
Limiting the focus distance range can improve focus lock times.
Autofocus Stop buttons near the objective lens allow autofocus to be temporarily stopped.
Background blur quality is excellent thanks in part to an 8-blade aperture.
This lens makes it easy to create a very diffusely blurred background.

As you can see in the picture above, there is a minimum height requirement for using this lens!
Mikayla has a few years to go.
She thinks she is big stuff though!
I was laughing when I took the picture, but I have gotten many more laughs from the online discussions that have occurred over this picture.
Just to set the record straight ...
1. I did not use the 500 to tie the girl down.
2. I did not make her carry it for me.
3. My wife is just outside of the picture to the left - there was NO CHANCE my 500 was going to hit the floor!
Thanks for the laughs!

Canon's 2008 Super Telephoto lens lineup is shown above.
Beautiful, aren't they?
The shortest lens standing on its rear cap in the center is the Canon EF 200mm f/2.0 L IS USM Lens.
To its left is the Canon EF 300mm f/2.8 L IS USM Lens.
Continuing left, the Canon EF 400mm f/2.8 L IS USM Lens is shown resting on its tripod ring.
Moving the top-most lens - this is the Canon EF 800mm f/5.6 L IS USM Lens.
Below it is the Canon EF 600mm f/4 L IS USM Lens
and the bottom-most lens is the Canon EF 500mm f/4 L IS USM Lens.
Here is another look at these beauties ...
Use the top selector to choose the Canon EF 500mm f/4.0 L IS USM Lens view to compare with the lenses and views available below.
Dragging your mouse down over the labels will show you the respective lens in the lower image.
Build quality is in line with other lenses in the Canon L Series - professional grade.
Of course, with a lens of this size, quality build brings along weight.
Canon has made an effort to keep the Canon EF 500mm 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.
IS (Image Stabilizer or Image Stabilization) allows the Canon EF 500mm f/4.0 L IS USM Lens can be handheld a full 2 stops lower than a 500mm non-IS lens.
Keep in mind - IS does not help stop a moving subject, but it does amazing things for a moving camera/lens.
With a super telephoto lens, image stabilization is even important with tripod use as wind and other destabilizing sources can add movement to your setup.
Fortunately, the IS version on this lens is tripod-sensing.
The Canon EF 500mm f/4.0 L IS USM Lens knows that a tripod is being used when vibrations go below a certain level.
Keep IS turned on when mounting the 500 L on a tripod to take advantage
of this secondary IS mode - reducing mirror slap, shutter and tripod vibrations.
The Canon EF 500mm f/4.0 L IS USM Lens is equipped with a Focus Preset feature.
Set the Focus Preset to a specific distance - when your shooting needs require that specific distance, press the Focus Preset button.
Autofocus Stop buttons near the objective lens allow autofocus to be temporarily stopped.
When purchased from a reputable dealer, the Canon EF 500mm f/4.0 L IS USM Lens comes packed in a 24" x 11" x 11" (610mm x 279mm x 279mm) lens trunk.
A leather-like lens cover (it is more than a lens cap and a bit of a pain)
protects the large objective end of the lens.
The 500 L accepts 52mm rear drop-in filters.
My primary use for the Canon EF 500mm f/4.0 L IS USM Lens is wildlife and bird photography where I need portability.
When you are going after the little critters, you cannot have too much focal length.
AND, paired with the Canon Extender EF 1.4x II, the 500 L yields a 700mm f5.6 IS lens.
The 500 L is also compatible with the Canon Extender EF 2x II.
I also use the 500 L for large field sports where it performs superbly.
Prior to purchasing the Canon EF 500mm f/4.0 L IS USM Lens, my bird and wildlife lens was my
Canon EF 300mm f/4.0 L IS USM Lens
along with a Canon Extender EF 1.4x II.
This worked well, but did not give me enough reach.
I simply missed a lot of good opportunities - I was too far away or I scared off the subjects by trying to get into range.
Using the Canon Extender EF 2x II
was not an option for me personally because the image quality of the combination was not where I required it to be,
and at a minimum aperture of f/8.0 my then-current Canon 10D would not auto-focus.
The next logical/significant step was the Canon EF 500mm f/4.0 L IS USM Lens.
This lens had the best combination of features for what I wanted.
Reach, weight, IS, price - a bit too high, but ... and image quality:
The MTF chart is only slightly below that of the Canon EF 300 f/2.8 L IS Lens -
which is about as good as it gets.

Who said the Canon EF 70-200 f/2.8 IS L Lens (above left) was big? The Canon EF 500mm f/4.0 L IS USM Lens hood (above right) could swallow it up! The 500 is pictured with a Wimberley P40 Lens Plate attached to the tripod collar.

The relatively large Canon EF 300 f/2.8 IS L Lens (above left) is noticeably smaller than the Canon EF 500 f/4 IS L Lens (above right). Both lenses have Wimberley Lens Plates attached to their tripod collars and lens hoods in place.

The Canon EF 300 f/2.8 IS L Lens trunk (above top)
is noticeably smaller than the
Canon EF 500 f/4 IS L Lens trunk (above bottom).
The Canon EF 500mm f/4.0 L IS USM Lens is right on the edge of being able to be freely handheld for a few shots.
I frequently use it in this manner - often when there is no time to setup a tripod.
You certainly should not expect to handhold this lens in position for very long.
This of course means mounting it on a tripod or utilizing a monopod, groundpod, bean bag, car, tree, knee, ...
