The Kowa LMVZ41A 1/2" Varifocal Auto-Iris Lens (4 to 10mm ) incorporates a 3-Cam design. This innovative system solves the problem of de-centering, which sometimes occurs in the conventional pole system. Not only is the movement of the lens impaired by de-centering, but the optical performance suffers too. The 3-Cam design also reduces internal reflection. As a result, the image obtained by this design is much sharper than that of the conventional pole system. With the 3-Cam design, you can expect high optical performance and a longer service life.
