Fisheye Lens for Surveillance and Robotics Cameras

Fisheye 2.2mm M12 Lens

This full horizontal 2.2mm miniature fisheye lens provides a 196 degree Horizontal Field of View. The overall system sharpness (SFR) and distortion exceeds the 12MP resolution of the Raspberry Pi High Quality Camera. This is equivalent to a 10mm lens used on a 35mm full frame camera. This lens is compatible with the off-the-shelf Raspberry Pi HQ when using a M12-CS mount adapter.

Performance Benchmark

Objectively characterizing the performance of a camera requires dozens of different metrics. While all of these are looked at by professional camera engineers, many are unnecessary for hobbyist component selection when a predetermined image sensor issued. For entry level camera engineering sake, we recommend starting with four first order system performance metrics: sharpness, color, shading and field of view.
