    Comments about Fujinon Varifocal Lens (2.8-12mm, 4.3x Zoom):

    This lens seems solidly built and offers a great picture quality. Alos, the auto iris cd connection makes for a much more consistant image and the cable is long enough, without being too long, to connect to the dc port on all my cameras. However, i was a little suprised at the size of the lens but it makes snese that it is as big as it is since it allows for a 4.3x optical zoom. There is a very slight portion of the zoom that will not focus. Specifically, this is when the zoom is as wide as the lens allows. But it is such a small amount of zoom that I can easily forgive it.Overall, this is going to be my go to lens for when I need anything more than a 2.8x zoom. Otherwise I would use the 3 MP Varifocal Lens (2.8-8mm, 2.8x Zoom) since it's much smaller.

      Comments about Fujinon Varifocal Lens (2.8-12mm, 4.3x Zoom):

      Nice lens for an HD-SDI 1920 x 1080 30P camera. Good zoom range. It's a Varifocal lens, as all are a slight pain in the .... to operate but once you have found your zoom and focus spot it is good. A little pricey but wanted good optics for 2.1mp camera.
