The Tamron CS-Mount 3 to 8mm Varifocal Fixed Manual Iris Lens is a great addition to any CCTV camera and facilitates easy focal length adjustments without having to move the camera from its installation point. The adjustable iris lens ensures that the camera captures detailed images even in areas with varying light intensity. The lens features an iris range of f/1.0 to 360, which makes it suitable for surveillance in low-light as well as bright light conditions.

The aspherical lens surface ensures corner-to-corner sharpness in image reproduction for all aperture settings. Moreover, this IR-corrected day/night lens captures clear images, eliminating focus shift and infrared bleed.

    CS-Mount 3 to 8mm Varifocal Fixed Manual Iris Lens is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from A cheap versatile industrial lens The Tamron 13VM308ASIRII is a cheap versatile lens for industrial inspection cameras; it is also good for IR. The image is almost as good as the more expensive megapixel version M13VM308. These lenses are also available with auto apertures, which would be useful in variable light conditions with appropriate CCD units.

    Rated 4 out of 5 by from Plastic body can be broken with heavy use Further to my earlier review, I would like to add that the plastic body of this lens can easily be broken open if the central ring is forced. It is most suitable when the lens does not often need to be adjusted. It focuses down to 100mm, but the depth of focus is then small.
