Canon 600mm f/4 L IS USM EF-Mount Lens {Gel}

The EF 600mm f/4L IS USM is a professional level large-aperture super-telephoto lens for Canon EOS SLR Bodies.  The 600mm f/4L IS is an premium lens for demanding photographers who want the best possible ultra high magnification images.

The EF 600mm f/4 L IS USM is one of Canon's very best L-Series lenses.  This top of the line design produces outstanding images with world class sharpness contrast and color.  Delivering an f/4 aperture in a high quality 600mm lens up to Canon's L-Series standards requires a tremendous amount of optical engineering and material; very few lenses in the world use more glass.  The lens also incorporates Canon's IS (Optical Image Stabilizer) technology to help reduce loss of image sharpness due to camera and lens movement.  Telephotos magnify the slightest movement even on a tripod or monopod and the IS system helps counteract the effect.

The EF 600mm f/4 L IS USM is one of the very best outdoor, wildlife, and large field sports photography lenses made.  The f/4 aperture coupled with it's extremely narrow 4°11" angle of view (diagonal) place this lens in a very select league of ultra-pro telephotos able to produce the very highest magnifications with necessary fast shutter speeds.  The AF system is fast and offers several amenities for customizing set up including a focus limit switch, focus preset/recall, AF stop button, and full time manual focus override.

The 600mm f/4 L IS USM is simply superb at isolating subject matter.  Few lenses allow the user to select such as narrow sliver of a background or compress perspective as much while delivering so much background blur and crisp focus.

Canon introduced the EF 600mm f/4L IS USM in Late 1999.  It replaced the well regarded EF 600mm f/4L USM non-IS model.  Improvements include weight reduction, more responsive AF, and the Image Stabilizer.  In 2011 Canon introduced the EF 600mm f/4L IS USM II which offers a new optical design, refinements to the IS system, some additional weight reduction, and tripod mount options.  Because the EF 600mm f/4L IS USM performs at an incredibly high level, it remains a very popular choice (and argue-ably a better value) given it's more affordable pricing.
