| Tamron Co. Limited announce a new addition to its extensive Vari-Focal lens line-up that covers the telephoto range. The new 1/3" 20-100mm F/1.6 Aspherical Vari-Focal covers the telephoto range that is normally covered only by zooms, yet the zoom function that makes the lens more costly is not utilized in many installations. The new Tamron Vari-Focal is an efficient replacement from the point of view of both cost and size.
With a focal-length range that covers everything from moderate to super-long telephoto, a fast F/1.6 aperture that ensures bright imaging even in dimly illuminated areas and aspherical optics that provide outstanding image quality in a compact, lightweight package, Tamron’s new 20-100mm F/1.6 for 1/3-inch CCD cameras is a significant new entry in the CCTV surveillance and security industry. Until now, security systems distributors, installers, and end users often use expensive motorized zoom lenses just to get the reach they needed. Or they had to use shorter-focal-length lenses mounted on poles, a system that means greater installation costs for trenching and wiring, less convenient maintenance, and susceptibility to image-degrading vibration.
The Tamron 20-100mm F/1.6 eliminates all these problems and provides far greater flexibility in security and surveillance installations than any previous lens in its class. A typical example would be a camera aimed at a parking lot gate for license plate identification. By allowing the camera to be mounted on a distant building wall or roof, this high-resolution super telephoto lets you achieve greater steadiness and stability plus easier camera maintenance and adjustment, all while capturing images of unparalleled clarity and definition. Also, being free to place the camera at a greater distance minimizes the need to conceal it in sensitive applications, and allows the camera to be mounted on a wall opposite the target area, giving a clear, direct shot of faces and other essential details. This latter capability is especially important at locations ranging from airports to casinos, where excessive camera-to-subject angles may prevent the camera from capturing critical information. |
