I bought the LK002 low-distortion lens kit from your Amazon store to use with the B0031 camera and a Raspberry Pi Zero W. I have both still images and video streaming working. The FOV with the default B0031 lens was too narrow for my purpose.
In the LK002 kit, both the 65 degree (LN015) and 90 degree (LN014) lenses will only focus to a distance of about 10mm, and that’s with the lenses screwed all the way into the 7mm lens holder as far as it will go (with care not to damage the sensor). I cannot focus on anything beyond 10mm.
The 70 degree FOV lens (LN013) works better and can focus to a much wider range of distances. It may be good enough for my needs, but it looks like there may be a problem getting the entire image in focus.
My requirement is to image a full US Letter page 216 x 280 mm (8.5 x 11 inches) from a distance of approximately 235mm. I can compensate for lens distortion in software, so low distortion is nice, but not essential. If you have a better camera/lens combination you can recommend for this setup, even if it requires a different interface or controller (e.g. USB, ESP32, etc.) I would appreciate your suggestions.
For the focus problems with the 65 degree and 90 degree lenses from the LK002 kit, please let me know if this is expected or if I should be able to focus beyond 10mm with the B0031 camera.
