Very good, very cumbersome assembly

The actual wide-angle lens of the camera I am very satisfied. She does exactly what it should only provide for a wider range. Clear the quality is thus just on the edge of not better, but this is due to the optics. The comments of some reviews that it is only in the center is sharp and thus useless in the dark, I could not tell. With switched-infrared, although it is dark, the image detail is but just like the day.

Negative is the assembly: unscrew the original is easy to clean Put the new well. However, contrary to the instructions you should only turn the black lens with a lot of strength in and then sit on the white paper. Otherwise, the paper slips because of the slowness only on the lens and not a millimeter turns pure. I can some resent an unsharp and blurred picture comprehend. This is because the lens has been mounted either too low or too far removed from the reasons mentioned. It is generally very expensive, the fine adjustment of the lens for accurate focus. By the manufacturer I would hope an adapter for screwing in the lens.
