Our take on the 2X Fisheye Lens 2.1mm 5MP Lens Wide Angle Lens HD Network Lens 180 Degree Wide Angle of View

This is a small 2.1mm fisheye board lens with a 5MP rating and a 1/2.5" image format, sold as a pair. It screws into an M12 mount and gives a very wide view, listed at 160 degrees in the specs and 180 degrees in the name. It suits people building or repairing security cameras, action cams and DIY camera projects who want a wide field of view on a small sensor. Against branded M12 lenses it is a cheap way to get a fisheye look, but it has no brand support and the wide angle brings heavy barrel distortion at the edges.

Cons

  • Heavy fisheye distortion at the edges
  • Fixed aperture of f/2.0 limits low-light use
