American Dynamics LD41016CS 1/2" CS Mount 4.5-10mm F1.6 DC Auto Iris Lens BRAND NEW! FREE SHIPPING!! CLOSE OUT PRICING FOR THIS ITEM!!! LOWEST PRICE you will have ever seen for this!!! The American Dynamics lens range, of which the LD41016CS is a part of, is very expansive and is wide enough to cater to all customer needs. Available in 1/3" and 1/2" formats and fixed and varifocal lengths, all of the American Dynamics lenses are especially designed to deliver good picture quality. Note that all of the lenses in the American Dynamics lens range have high quality, compact designs and come equipped with CS mounts. Further, note that the performance of these lenses is the best when these are used with American Dynamics cameras. The American Dynamics lenses can be divided into three categories: auto iris lenses, manual iris lenses, and IR-corrected auto iris lenses. The American Dynamics auto iris lenses are specifically designed to produce consistent video signals under variable-light conditions. These high quality auto iris lenses offer high contrast, color corrected optics (for clear, true images), fast signal response, and low geometric distortion. These lenses are apt for cameras used in spots where light conditions tend to vary frequently. Note that these auto iris lenses rely upon the circuitry present in compatible and suitably equipped cameras (that produce a DC output) to make adjustments to the lens iris accordingly. Further, the American Dynamics auto iris lenses come equipped with a slip clutch for easy mounting. The American Dynamics manual iris lenses are well-suited for situations wherein the scene and lighting requirements vary little and are relatively constant. These lenses provide a budget-friendly option (as compared to auto iris lenses) when used with electronic shutter-equipped cameras. These manual iris lenses are specifically designed to be used with modern CCD imagers that place much strain on the lenses in terms of contrast, resolution, and geometric distortion. The American Dynamics manual iris lenses provide high contrast, color corrected optics (for clear, true images), and fast signal response. Much like their auto iris counterparts, the American Dynamics manual iris lenses, too, come equipped with a slip clutch for easy mounting. The American Dynamics IR-corrected auto iris lenses are specifically designed to compensate for the variations between infrared and visible light conditions to consistently provide sharp images in a plethora of situations. The American Dynamics infrared lenses feature a built-in slip mount mechanism that enables you to rotate the lens even after it is mounted on a camera, thereby offering much increased flexibility. These IR-corrected lenses have a special multi-layer coating design that prevents transmittance fall-off in the infrared range, to minimize ghosting and flare usually observed in backlit situations. This ensures much improved picture performance even in dim-light conditions and when infrared illumination is in use. Furthermore, the advanced optical design of the American Dynamics IR-corrected auto iris lenses eliminates the shifts in focus typically encountered in the near infrared range to yield better images. 1/3" format / 1/2" format CS mounts Color corrected optics High quality, compact design Fixed and variable focal lengths Neutral Density (ND) Filters Slip clutch on lens mount for easy positioning Imager Size 1/2" Mount Type CS Focal Length 4.5-10mm Aperture F1.6-360 Iris Operation DC Auto Iris Lens Focus Operation Manual Angle of View Horizontal / Vertical: 81.3-36.2 / 60.4-28.7 Minimum Object Distance (M.O.D.) 0.3 m Filter Size N/A Diameter and Length 1.7 x 1.7" (43 x 44mm) Weight 1.8 oz (50g) TERMS OF SALE: If, after receiving this item you discover that it was not the one you wanted, simply return it for a full refund within 14 days.
