CANON EF 100-400MM F/4.5-5.6L IS II USM LENS – SECOND HAND
The Canon EF 100-400mm f/4.5-5.6L IS II USM Lens – Second Hand is a professional-grade L-series super-telephoto zoom designed for photographers who demand exceptional reach, sharp image quality, fast autofocus and dependable performance across wildlife, bird, sports, motorsport, aviation, safari and outdoor photography. Covering an extremely versatile 100-400mm focal length range on full-frame Canon EF-mount cameras, the lens allows photographers to quickly move between wider environmental compositions and tightly framed distant subjects without changing lenses, while APS-C Canon DSLR users gain an approximately 160-640mm equivalent field of view for even greater apparent reach. Its sophisticated optical construction uses one fluorite element and one Super UD element to minimise chromatic aberrations and colour fringing while maintaining excellent sharpness, contrast and colour accuracy throughout the zoom range, with Canon's Air Sphere Coating helping to reduce flare and ghosting when working in difficult lighting conditions. A built-in 4-stop Optical Image Stabilizer provides additional confidence when shooting handheld and offers three dedicated IS modes for general photography, panning and unpredictable subjects, while the fast ring-type Ultrasonic Motor (USM) delivers responsive, quiet autofocus with full-time manual focus override. The lens focuses as close as approximately 0.98m and achieves an impressive maximum magnification of approximately 0.31x at 400mm, making it surprisingly capable for detailed close-ups of smaller wildlife, flowers and other subjects. Professional handling is enhanced by an adjustable zoom torque ring, focus distance limiter, weather-resistant L-series construction, fluorine coatings on the exposed front and rear elements and a removable rotating tripod collar. Combining serious optical performance with flexible 100-400mm coverage, effective stabilisation and rugged construction, the Canon EF 100-400mm f/4.5-5.6L IS II USM – Second Hand remains an outstanding telephoto option for Canon DSLR photographers as well as EOS R mirrorless users who want to take advantage of high-quality EF glass through a compatible Canon EF-EOS R Mount Adapter.
Key Features:
- Professional Canon L-Series Telephoto Zoom – Part of Canon's premium L-series lens range, the EF 100-400mm f/4.5-5.6L IS II USM is engineered for demanding photographers who require high optical quality, dependable autofocus and robust construction for professional and enthusiast photography.
- Versatile 100-400mm Focal Length Range – The broad telephoto zoom range provides tremendous framing flexibility, allowing photographers to capture everything from larger subjects and environmental wildlife compositions at 100mm to distant animals, birds, aircraft and sporting action at 400mm.
- Ideal for Wildlife Photography – The combination of long telephoto reach, fast autofocus, effective image stabilisation and excellent optical performance makes the EF 100-400mm L IS II particularly well suited to wildlife photography, including safaris, game reserves and general outdoor photography.
- Excellent for Bird Photography – At 400mm, the lens provides the reach needed to photograph birds from a practical working distance while maintaining the image quality required for detailed feather reproduction and subsequent cropping.
- Perfect Safari Telephoto Lens – The flexible zoom range is particularly valuable on safari, where subjects can move rapidly between close and distant positions and changing lenses may cause photographers to miss important moments or expose the camera sensor to dust.
- Strong Sports & Action Performance – Responsive USM autofocus and the ability to rapidly adjust framing across the 100-400mm range make the lens a strong choice for field sports, motorsport, cycling, equestrian events and other fast-moving subjects.
- Excellent Motorsport & Aviation Lens – Long reach, panning-oriented stabilisation and flexible composition make the lens particularly useful for racetracks, airshows, aircraft photography and other situations involving rapidly moving distant subjects.
- One Fluorite Optical Element – A high-performance fluorite element helps suppress chromatic aberration and maintain excellent image quality, particularly important when working at longer focal lengths where optical imperfections can become more noticeable.
- One Super UD Element – Canon's Super Ultra-Low Dispersion glass further controls colour fringing and chromatic aberration, contributing to strong sharpness, contrast and colour accuracy across the image.
- Air Sphere Coating – Canon's ASC technology is designed to suppress internal reflections, reducing flare and ghosting when photographing subjects in challenging lighting or when strong light sources enter the frame.
- 4-Stop Optical Image Stabilizer – Built-in optical stabilisation provides up to approximately four stops of shake correction, helping photographers achieve sharper handheld photographs at slower shutter speeds than would otherwise be practical.
- Three Image Stabilisation Modes – Dedicated IS modes allow the stabilisation system to be adapted to different shooting situations, including conventional handheld photography, panning and subjects that move unpredictably.
- IS Mode 1 for General Photography – Standard image stabilisation corrects camera shake across multiple directions and is ideal for general handheld wildlife, portrait, travel and telephoto photography.
- IS Mode 2 for Panning – Designed for subjects moving predictably across the frame, this mode is particularly useful for motorsport, cycling, running wildlife and other panning applications.
- IS Mode 3 for Unpredictable Action – Stabilisation is applied during the actual exposure rather than continuously affecting the viewfinder image, helping photographers follow subjects whose direction of movement may suddenly change.
- Ring-Type USM Autofocus Motor – Canon's ring-type Ultrasonic Motor provides fast, accurate and quiet autofocus performance, an important advantage when tracking moving wildlife, birds, athletes and vehicles.
- Full-Time Manual Focus Override – Photographers can manually fine-tune focus without first switching the lens out of autofocus mode, providing additional control in challenging situations.
- Focus Distance Limiter – The lens provides selectable focusing ranges to help reduce unnecessary focus searching when photographing subjects that are known to be farther away.
- Minimum Focus Distance of Approximately 0.98m – Despite being a powerful super-telephoto zoom, the lens can focus surprisingly close, substantially expanding its usefulness for smaller subjects and detailed compositions.
- Up to 0.31x Maximum Magnification – At 400mm and minimum focusing distance, the lens provides approximately 0.31x magnification, allowing impressive close-up images of flowers, insects, reptiles, textures and smaller wildlife without requiring a dedicated macro lens.
- Variable f/4.5-5.6 Maximum Aperture – The maximum aperture ranges from f/4.5 at the shorter end to f/5.6 toward the telephoto end, balancing useful light-gathering capability with the size, weight and portability expected from a professional 100-400mm zoom.
- 9-Blade Circular Aperture – A nine-blade diaphragm helps produce smooth, attractive out-of-focus areas, allowing photographers to visually separate wildlife, portraits and other subjects from distracting backgrounds.
- Strong Subject Isolation – The combination of long focal lengths, close focusing and telephoto compression allows photographers to create strong background separation and emphasise subjects even when working with the lens's variable f/4.5-5.6 aperture.
- APS-C Equivalent Field of View of Approximately 160-640mm – When mounted on a compatible Canon APS-C DSLR with a 1.6x crop factor, the lens provides an angle of view equivalent to approximately 160-640mm on full frame, making it particularly attractive for wildlife and bird photographers seeking additional apparent reach.
- Compatible with Full-Frame Canon DSLRs – The EF mount provides native compatibility with Canon full-frame EOS DSLRs such as the EOS 5D and EOS-1D X families, subject to the normal compatibility of the individual camera body.
- Compatible with Canon APS-C DSLRs – The lens can also be used natively on compatible Canon EF/EF-S mount APS-C DSLR bodies, providing significantly tighter framing because of the smaller sensor's 1.6x crop factor.
