Canon EF 100-400mm f/4.5-5.6L IS USM - Good Condition | Telephoto Zoom Lens | Professional L-Series Wildlife & Sports Optics

The Canon EF 100-400mm f/4.5-5.6L IS USM (S/N: Not specified) is a legendary cornerstone of the professional "L" series, widely regarded as one of the most versatile telephoto zooms ever produced for the EF mount. Engineered for the rigorous demands of wildlife, sports, and aviation photographers, it features a sophisticated optical design including Fluorite and Super UD (Ultra-low Dispersion) glass elements to provide world-class sharpness and contrast. This lens is famous for its "push-pull" zoom mechanism, allowing for lightning-fast focal length adjustments to track moving subjects. Equipped with a two-mode Optical Image Stabilizer (IS) and a ring-type Ultrasonic Motor (USM) for near-silent, high-speed autofocus, this lens delivers the mechanical precision and optical excellence required for gallery-quality imagery in the most challenging environments.

Introductory Paragraph The Canon EF 100-400mm f/4.5-5.6L is the definitive "workhorse" for the outdoor photographer. This specific unit is highly prized for its ability to pull distant subjects into intimate view with incredible clarity. The 100-400mm range is a favorite because it covers everything from tighter portraits at the wide end to high-magnification wildlife shots at the long end. Because it belongs to Canon's professional "Luxury" line, the color rendition is exceptionally punchy and the build quality is tank-like. Whether you are using it on a classic EOS film body, a modern DSLR, or adapting it to a mirrorless R-series camera, this lens provides a tactile, high-performance experience that remains a benchmark in telephoto design.

Condition Report Good condition. The lens barrel shows normal signs of light professional use and minor cosmetic surface wear consistent with its age. The front and rear glass elements are clear, free from fungus, haze, or significant scratches. The "push-pull" zoom mechanism is smooth, and the tension adjustment ring functions correctly. The autofocus (USM) and Image Stabilizer (IS) systems have been tested and are operating to factory specifications. The internal aperture blades are clean and snappy. The Canon EF mount is in excellent condition, ensuring a secure fit to your camera body.

Specialist Note "The 100-400mm 'Push-Pull' is a lens that truly feels alive in your hands. What I love about this model is how fast you can react to a bird taking flight or a race car coming around a corner; you can zoom from 100 to 400 in a split second. The Fluorite glass in this lens gives images a specific 'bite' and clarity that is hard to find in non-L optics. It’s a rugged, professional instrument that handles beautifully despite its size. This specific set is great because it includes the original LZ1324 hard case and the ET-83C hood, which are essential for protecting such high-end glass. It’s a timeless piece of Canon engineering that still delivers professional results today."
