Canon objectif zoom optique 16 x  - 5.5-88 mm /1.6-2.6 IS II, le meilleur objectif stabilisé pour Canon XL1, XL1S, et XL2 (voir plus bas l'article de dvinfo.net) avec son paresoleil.   Portée mini de la mise au point 2 cm     Réglage de la mise au point Automatique, manuel     Structure de l'objectif 10 groupe(s) / 12 élément(s)     Fonctions spéciales Zoom     Taille du filtre 72 mm     Longueur 13.4 cm     Poids 650 g              Product Description          This lens resolves over 600 vertical lines to record an extraordinarily sharp image. By exceeding the DV standard of 500 TV lines, the Canon lens delivers greater visual "sharpness" through its higher sensitivity in the all-important 100 to 250 TV line resolution area. It is fitted with a variable angle prism for optical image stabilization, has an ND filter, manual focus and zoom rings, plus a push AF function.          From the Manufacturer          A key feature of the Canon XL-series camcorders (and the only MiniDV format camcorders with this feature), is the XL mount interchangeable lens system. Unlike other systems, the XL2 offers users the ability to change lenses, whether from within the XL series of video lenses, third-party cine lenses, or Canon's extensive range of photo lenses. This not only makes the XL2 a far more versatile camera, it also opens up incredible opportunities for the XL2 user.            Equivalent 35mm focal length, 16:9: 43.1 to 689.6 millimeters       Equivalent 35mm focal length, 4:3: 52.8 to 844.8 millimeters          Automatic and manual 16x optical zoom lens     Manual and auto focus switch with Optical Image Stabilization     Servo-controlled even in manual mode with slow, low-speed crawling zoom     Neutral density filter, free-spinning focus and zoom rings     Compatible with Canon XL1, XL1S, and XL2 camcorders            The 16x Manual Servo lens is perhaps the sharpest tool available for XL1/XL1S shooters who need more precision in their imaging. Its optics are excellent, as you would expect from one of the world�s premier lens manufacturers. Its true manual focus ring is a joy to use. The stationary front element makes attachment of accessories much easier than with its predecessor, the 14x Full Manual lens. The zoom servo is smooth          (dvinfo.net)               Focal Length: 5.5 - 88 mm    Dimensions: 92 x 134 mm    Weight: appx. 1 lb 6 oz    Filter Dia.: 72 mm    Stabilizer: Yes    Min.

- The Audioquest Forest HDMI cable is compatible with 1080p, 4K HDR and 3D video streams as well as the ARC function. Its construction uses 0.5% silver plated LGC (long grain structure) copper conductors.  - This solution allows excellent conduction of the highest frequencies which always pass through the surface of the cable, silver being a conductor offering higher performance than copper. The conductors are insulated by high density polyethylene, the PVC outer sheath providing insulation with the outside. Type A plugs are shielded and the contacts are gold plated to increase cable durability. - The Audioquest Forest HDMI cable is optimized to deliver signals in a certain direction, which is why it is marked at each end with an arrow indicating the optimal direction of signal delivery. -  HDMI 2.0 4K (24/25/30/50/60) + HDR compatible. They offer 18 Gbps bandwidth.
