Good question. It looks like the Raspberry Pi HQ camera module (the bit with the sensor) is rated at 12MP. My guess is that the angle of this lens means you can only make use of the middle portion of the sensor, in this case 10MP’s worth of it. And as there’s only one sensor module on the market that this lens can screw onto, they can tell you the effective megapixel rating of the lens. There’s also a ‘wide angle’ 6mm lens [1] available for the same camera module, rated at 3MP, which I assume casts the image on a even smaller portion of the sensor. I could be completely wrong though, not an expert.

- JKCalhoun 5y agoI don't think you are correct. For this reason only: I have played with the Raspberry Pi HQ camera module and a pair of lenses for it and the frame-grab software never returned an image with a black (or otherwise) border. From your description I would instead expect a thick black border around the image where no photon data was captured. To be sure the frame-grab tool could be sensing the lightless border from the image and cropping, but I doubt it's that clever.
- brudgers 5y agoYour description of the frame grab software output is consistent with the proposed degree of cleverness.
