This review is from: D-Link DVC-20 2 x 4-8mm Varifocal Lens, For DVC-1000/1100 (Electronics)

I purchased it to better frame the video picture.
I found the following problems:
(1) focus depth very narrow.
(2) focus does not work on both ends of the zoom range.
It may be a design or manufacturing defect.
I returned it after a week of usage.
