I'm using the 5mp Cam on my rev. b rPi and I'm having trouble with the focus length. The usual problem is that the focus isn't close enough, my problem is that the focus is too short. I'm using it as a webcam in my garden and the length is about 30m. The focus is at about 0.5m so most of the picture is a bit blurred through this. Is there any possibility to adjust the focus to get the focus in the middle of the picture?
I've heard about attaching an additional lense to the camera, but does this also work to increase the focus length?
I've set the quality of the image to 89% while converting it for the upload, if this is an important information you need. I've included a picture where you can see, how my focus is set.
