Hi!
I need a fisheye camera in a design. Most webcam actually have a standart threaded lens, so replacing them with any other lens found on EBay is quite easy.
Does the two cameras sold by SparkFun have a threaded lens port? Is it possible to replace the lens? If not, could it be possible by adding a “platic over-mold” that would be threaded (most webcams are a bare cmos sensor, with a platic enclosure including the treaded port)?
Whatever the answers, it would be real nice to have 60-90-120 degrees lenses, to have a very wide range, very small surveillance prototype
