Cellphone FoV Lens for Raspberry Pi HQ Camera

Cellphone 4.2mm M12 Lens

This 12MP+ 4.2mm M12 lens provides 72 degree Horizontal Field of View with zero distortion. The field of view when used on the Raspberry Pi High Quality Camera is wider than most normal cell phone cameras. This is the same as if a 25mm 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.
