Tamron has just released two new 1/3”-format 3.0-8mm F/1.0 Vari-Focal lenses, which are IR-corrected, delivering 650 TV-lines resolution. The 13VM308ASIRII and 13VG308ASIRII were developed fulfilling market demand for higher quality images and high sensitivity for surveillance cameras. The new lenses come with Asphrical element and an LD (Low Dispersion) glass element. Furthermore, the new lens offer clear images without color smear by way of minimizing chromatic aberration. Additionally, the lenses have been covered with multi-layer coatings as a countermeasure against light reflection.
The introduction of new IR-corrected Vari-focal lenses have made possible to increase light sensitivity, allowing the camera to stay in color mode for an extended period of time, thanks to the fast maximum aperture of F/1.0. The two newly developed lenses are optically IR-corrected to prevent focus shift, so the cameras can be used during both day and night.
