Vari-Focal Lenses

Tamron USA announced the development of two 1/3"-format 2.8-8mm F/1.2 Vari-Focal lenses (Models M13VM288IR-manual iris; M13VG288IR-DC auto iris) that are compatible with 3-Mega-pixel-Day/Night cameras and deliver full high-definition 1080p images over the entire focal length range, both in visible and near-infrared light ranges. As a result of the rising demand for higher image quality in security systems, requirements for higher pixel sensors are increasing. In addition to this trend, the demand for Mega-pixel Day/ Night cameras for night time surveillance is also increasing. To meet the trends and needs of the market, the company's engineers challenged themselves to expand the specifications of Megapixel camera lenses and have successfully developed two new, state-of-the-art Vari-Focal lenses that are compatible with even 3-Mega-pixel-resolution systems and at the same time correcting the shift in focus for the Day/ Night function. The lenses will e.g. be presented at Ifsec 2010.
