Incorrect focusing at close range - solution.

[Batilla 0]

This post is about how I solved a close-up focusing problem. Hope someone can benefit from it. It was a bit foggy and rainy here yesterday. Then what is near became blurry, and I tried to zoom in and out, but then it only focused clearly at a distance. Then the weather improved, but the camera still wouldn't focus at close range. My solution was to wait until it got dark outside, and turn off the Ir Led on the camera. The background then became darker than the area close to the camera. Then the camera would focus on the close-up again. Today with daylight it still focuses correctly.
