The Canon EF 200-400mm f/4.0L IS USM Lens with Internal 1.4x Extender is a high quality super-telephoto zoom lens with a built-in 1.4x extender. The additional extender gives extended focal range and maximum aperture up to 280-560mm f/5.6.

 Auto Focusing is achieved by a ring-type Ultra-Sonic Motor (USM), an internal focusing system, dedicated AF algorithms and a high-speed CPU gives fast and quite auto focusing. The lens could also be focused manually to attain super fine focusing for highest level of professional photography. Fine tuning is also available in auto focusing mode as well. The Power Focus mode gives the highest level of stable imaging while video recording and playing besides recording. Focus Preset mode allows you to set a focus distance and automatically return to it with just a twist of the playback ring. Three Focus Limiting Ranges are provided to enable quicker AF in specific situations and AF stop buttons allow you to use the AF operation if needed.

The Image Stabilization system offers up to four shutter speed stops of compensation against camera movement, which most required while is shooting in low-light situations and at its long focal lengths. The static subjects are captured with special one for panning with moving subjects and Exposure Only mode that applies stabilization only during exposure, offering you the speed you need to follow fast, erratically moving subjects. The extender functions with a simple lever switch and is at the base of the lens.

The USM Lens features one Fluorite and four Ultra-low Dispersion optical elements that deliver sharper images with fewer chromatic anomalies. Super-spectra lens coatings minimize ghosting and flare and a Fluorine coating on the front and rear lens elements keep oily smears and fingerprints to a minimum.  In addition to its standard accessories, included with this lens are a monopod mount, lens strap, hard case and case strap.

  • Image Stabilization: Four stops of shake correction are provided by the lens' Image Stabilization system which delivers clearer images when shooting in low light situations, when your footing is uncertain or when fast shutter speeds are unobtainable. This lens has three stabilization modes: Standard, Panning and Exposure Only modes. Standard mode (Mode 1) compensates for vibrations in all directions and is effective when shooting static subjects. Panning mode (Mode 2) corrects vertical or horizontal shake depending on the orientation of the camera and is best when panning with moving subjects. Exposure Only mode (Mode 3) applies shake correction only during image exposure and is best used when needing to follow a fast and erratically moving subject. The IS system can also be turned off, and this is best when image stabilization is not needed, such as shooting on a tripod in bright light.
  • Fast and Accurate Autofocus: With an internal focusing system, Ultra-sonic motor (USM), high speed CPU and optimized AF algorithms, the 200-400mm f/4L provides fast, smooth and pinpoint accurate autofocus for use in a variety of applications.
  • Internal 1.4x Extender Switch: A built-in 1.4x optical extender allows you to extend the focal range of your lens with just a simple lever, avoiding time-consuming and potentially damaging lens changes. Located at the base of the lens, the extender has a lock mechanism that is easily disengaged to let you engage the extender. With the extender in place, the focal lengths of your lens increase to 280-560mm but the aperture narrows to f/5.6-45. With the extender engaged, the lens now contains 33 optical elements in 24 groups, its maximum magnification is 0.21x and its diagonal angle of view is 8°-50' to 4°-25'.
  • Focus Distance Range: You can set the focus limiting range to three distinct ranges for faster, more accurate autofocusing. The three ranges are: Full (6.56' to infinity); 6.56 to 19.69'; 19.69' to infinity.
  • Power Focus Mode: Using the playback ring, the Power Focus mode enables smooth, automatic focus shifts which are essential when using the EF 200-400mm f/4 for filmmaking. There are two speeds available in Power Focus Mode.
  • Focus Preset: It is possible to establish a preset focus distance and return to it immediately at any point while in AF, PF or MF modes with a simple left or right twist of the playback ring.
  • AF Stop Button: Four AF Stop Buttons located on the front grip ring allow you to temporarily pause autofocusing.
  • Fluorite and UD Lens Elements: One fluorite and four UD (Ultra-low Dispersion) lens elements correct for chromatic aberrations and provide sharp imaging throughout the zoom range.
  • Lens Coating: Optimized lens placement and coatings deliver outstanding color balance, while helping to minimize ghosting and flare.
  • 9-Blade Circular Aperture: The 9-blade circular aperture design helps to deliver beautiful, soft backgrounds.
  • Tripod Mount: A rotatable tripod mount is built into the lens and by loosening the orientation locking knob on the tripod mount you can rotate the camera for horizontal or vertical imaging without removing it from the tripod.
  • Drop-In Filter Holder: A rear 52(WII)-series drop-in filter holder is included with the lens and allows you to place separately sold pre-cut gelatin filters into the back end of the lens for specific applications.
  • Water and Dust Resistant: With its exceptional design and construction, the L-series 200-400mm f/4 lens is resistant to dust and moisture and ready for shooting in harsh conditions.
  • Fluorine Coating: Fluorine coating on front and rear lens surfaces reduces smears and fingerprints.
  • Security Slot: An attachment slot is provided for a wire-type security lock. The slot is located under the cover of the orientation locking knob. The wire-type security lock can be purchased separately.
