600mm T4.5 Prime lens. PL, EF or B4 mount available.  Please confirm mount at time of booking.

This lens has had the Optex modification and supplies the following with the lens:

  • ARRI LS9 for 15mm bars mount.
  • Tiffen .3, .6 & .9 ND filters and clear filter.

The Canon EF 600mm f/4 L IS USM lens weighs in at 11.8 lbs and is 6.6" (168mm) in diameter and 18" (456mm) in length (without the lens hood attached). 

Canon has made an effort to keep the Canon EF 600mm f/4 L IS USM Lens as light as possible without sacrificing strength by utilizing a Magnesium alloy lens barrel. The carbon fibre 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.

As with all Canon Super Telephoto L Lenses, build quality of the Canon EF 600mm f/4 L IS USM Lens is excellent. The focus ring and the many switches resident on the lens all work smoothly. It will be obvious to any photographer that this is a very high quality piece of equipment - professional grade.

Although it is for the long focal length that many people buy the Canon EF 600mm f/4 L IS USM Lens, its image quality is excellent as well. The 600 IS has very decent sharpness wide open (including wide open full frame corners) and improves some until stopped down 1 f-stop or so. 

A very small amount of vignetting is apparent at f/4 in full-frame body image corners (slightly less than from the 500 f/4 IS). CA (Chromatic Aberration) is very well controlled. Distortion is also negligible.

Like the rest of the Canon Super Telephoto lenses, the Canon EF 600mm f/4 L IS USM Lens is compatible with the Canon EF Extenders. Image quality with the Canon EF 1.4x Extender mounted is reasonable - especially for an 800mm f/5.6 IS lens. As always, this extender adds CA (Chromatic Aberration), adds barrel distortion, reduces contrast/sharpness and slows autofocus. Adding a Canon 2x Extender will result in a 1200mm f/8 IS lens that will autofocus only on Canon EOS 1-Series bodies and then only with the center focus point. Image results will show a noticeable amount of sharpness and contrast loss.  VMI provide these with the Canon 300/400/600mm prime lens.

Eliminating background distractions is generally desired when photographing birds and similar subjects. Combining a relatively wide 8-blade aperture with 600mm telescopic compression can turn a background into a beautiful, smooth blur.

Image Stabilization (IS) is an excellent feature present on the Canon EF 600mm f/4 L IS USM Lens. It will not stop subject motion, but makes a big difference in camera/lens motion. Both Mode 1 and 2 IS are available. Mode 1 IS attempts to stop camera/lens motion in all directions. Mode 2 IS allows panning with a moving subject. As with all IS-equipped lenses, an on/off switch allows IS to be disabled.

Even with the 600 L IS mounted on a tripod, IS helps stop vibrations as the IS version on this lens is tripod-sensing. The Canon EF 600mm f/4 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 Canon EF 600mm f/4 L IS USM Lens on a tripod to take advantage of this secondary IS mode - reducing mirror slap, shutter and tripod vibrations.

Utilizing Ring USM (Ultrasonic Motor), the Canon EF 600mm f/4 L IS USM Lens autofocuses very fast and has FTM (Full Time manual focus). AF accuracy is excellent in both one-shot and AI Servo modes. A 3-position focus limiter switch allows focusing distances to be limited to a specific distance range - 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.
