Tamron Co., Ltd. has developed two new F/1.4, 4-12 mm Vari-Focal lenses that are compatible with 1/2"-format megapixel-resolution cameras.
The development concept
The concept was to develop 1/2"-format lenses in the high-resolution Vari-Focal Lens series compatible with megapixel-resolution cameras. These lenses will take full advantage of the performance of high-resolution cameras and offer the resolving power required for true high-precision surveillance.
As is the case with the previously announced high-resolution lenses compatible with 1/3"-format megapixel-resolution cameras, these lenses are suited for high image quality surveillance, and can be used for a wide variety of applications.
Main features:
High image-quality lenses that make the best possible use of the performance offered by megapixel-resolution cameras
Lens designed for compatibility with 1/2"-format CCDs
High precision, high quality construction results in the highest possible performance
Environmentally sensitive design
