Tamron: evolving range of lenses for CCTV cameras

Tamron: evolving range of lenses for CCTV cameras. Who remembers the innovations of the CCTV market in 1986? I don’t, but I was only eight years old and was excited about my first computer, an Amiga 500. At that time it was the world‘s most advanced affordable home computer: 512 Kbyte Ram, 256 colours with an 8 Bit soundchip on board made Macintosh and PC computers look like big calculators. I wasn’t even aware that there was something like a CCTV market back then, and the market was, of course, slightly different from today‘s.

The CCD was introduced into the market a few years ago and, with it, the usability of CCTV cameras was improved tremendously. This made it possible to use the cameras in much more diverse situations.

Tamron was the first lens manufacturer which supported this development with the world’s first CCTV Vari-Focal lens, a 2/3” 8–16 mm with F/1.6 aperture. The lens was well received in the market and so Tamron continued to develop Vari-Focal lenses to meet the needs of the CCTV market. The 1/3” 3.5–8 mm Vari-Focal lens was introduced by Tamron in 1992 and started the so-called “Varifocal boom” in the CCTV market.

Many other lens manufacturers developed their own Vari-Focal lens with similar features and this focal length range is a very popular one even today.

Tamron widened its product line-up with the 1/3” 2.8–12 mm F/1.4 and the 1/3” 5–50 mm F/1.4 which were the first CCTV Vari-Focal lenses using aspherical lens elements. And exactly these same lens elements were built into the most commonly used CCTV lens of all, the 1/3” 3.0– 8 mm F/1.0 that Tamron introduced in 2002.

After that, Tamron was also the first to introduce IR corrective lenses and, in 2007, the first 1/3” Megapixel lenses developed for the CCTV market. These lenses (1/3”; 3.0–8 mm F/1.0; 2.4– 6 mm F/1.2; 5–50 mm F/1.4) are not only suitable to resolve Megapixel resolution right into the corners of a sensor but they have also a user friendly design. They feature a very large focus ratio to compensate for the depth of field decrease as well as the delay due to IP technology which makes it more difficult for the installer to obtain a well-focussed picture.

Just like the Amiga back in those days, Tamron CCTV lenses were always ahead of their time and bringing more features to the user than anybody else. Unlike the Amiga, Tamron lenses are still doing it today and, if you would like to see that live, we would be pleased to welcome you to our booth at the Ifsec, Hall 5, Stand B45
