    computar HG3Z4512AFCS-IR reviews

    HG3Z4512AFCS-IR 1/2" Varifocal Day/Night Lens (4.5-12.5mm) is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from silent auto iris Using one of these with a Watec B&W camera. The lens is completely silent.... so silent I had to unplug the 4 pin connector during changing lighting levels to verify it was working... Seems to be a good quality lens. Works well with an IR light source also. One thing that was disappointing is that Computar doesn't provide a 4 pin connector with the lens. Luckily I happened to have an extra one laying around and soldered it up. This lens has wires coming out of it that you can attach to your own connector. This connector can be purchased at @ if you need one. (also note I did not buy the lens here but wanted to leave a review for others considering it).
