A diagonal FOV of 83 degrees is approximately equivalent to a 4mm lens, assuming a 1/2.7" sensor like the IMX291. I think this is too wide, and will not really add much benefit over a regular lens. Especially if the 'telephoto' camera has a lower resolution than the main camera. A pair of 1440p IMX335 cameras would be a good choice though.The 6mm lens I tested before is only a little high than a regular lens.
I am checking a lens designed for car manufacture, the FOV(D) is about 83 degrees, and the FOV(H) is 65 degrees, will it be too wide for a telephoto lens?
If you think the FOV is too narrow for a consumer dashcam at 10mm or 12mm, I recommend that you try to find something in the range of 6mm to 8mm. For a 1/2.7" sensor, that means a lens with a diagonal angle of view in the range of 45-58 degrees.
