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 (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.
And super-focusing. Utilizing Ring USM (Ultrasonic Motor), the Canon EF 500mm f/4.0 L IS USM Lens focuses very fast, very accurately - and very quietly. FTM (Full Time manual) focusing is enabled. A 3-position focus limiter switch allows focusing distances to be limited to a specific distance range (4.5m to 10m, 10m to infinity, 4.5m to infinity) - or to be unlimited. Limiting the focus distance range can improve focus lock times and reduce focus hunting.
Autofocus Stop buttons (near the objective lens) allow autofocus to be temporarily stopped. This feature is handy when tracking action in AI Servo mode and one-shot-style focus is needed for a specific situation - perhaps a focus-and-recompose portrait of a motionless person, bird, landscape or other subject.
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, simply turn the white knurled playback ring on the end of the lens. Autofocus Stop buttons near the objective lens allow autofocus to be temporarily stopped.
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!
Image quality from the Canon EF 500mm f/4.0 L IS USM Lens is just as super as you would expect. This lens is impressively sharp wide open and maintains excellent sharpness right into full frame corners. CA (Chromatic Aberration) is negligible, color and contrast are very good. A slight amount of pincushion distortion is present. Full frame body users will notice a slight amount of vignetting in the corners.
Background blur quality is excellent thanks in part to an 8-blade aperture. This long focal length and relatively wide aperture of this lens makes it easy to create a very diffusely blurred background.
