1/3" 2.7~12mm Varifocal Auto Iris Lens

Common in lenses in the broadcast industry, the Kowa Varifocal Auto Iris Series LMVZ 272A 3-Cam Design is also incorporated in Kowa’s varifocal and zoom lenses. This innovative system has solved 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 LMVZ-272A 3-Cam Design, the customer can expect higher optical performance and a longer service life.
