•Aspherical
Special asphericalelements are used to achieve high resolution and high contrast performance over entire focal length range.

•Wide Dynamic Range
Tamron1/3” most common DC AI 3-8mm offer outstanding open aperture of F1.0. This means that these lenses are very suitable to be used for situations where light levels are extremely low and ever changing.

•IR Correction (ASIR model only)
The ASIR lenses are specially designed to minimized focus shift near infrared range by extending chromatic aberration compensation to include both daylight & near infrared ranges. The lens therefore suitable for 24hrs surveillance when combined with a day/night camera.
