The below calculator should allow you to get a rough idea of the right lens for you.
Find the Pixel pitch for your camera’s sensor;
- OV2710, OV9712, AR0144, = 3
- IMX179 = 1.4
- IMX214 = 1.12
This calculator is only a first-order approximation and doesn’t take into account lens distortion effects.
Gotcha’s when buying a lens;
- Buy the lowest distortion lens you can afford, if the seller doesn’t publish distortion info, be very afraid!
- Check that the imaging circle is correct for your sensor. Fitting a lens meant for a 1/4″ sensor onto a 1/3″ sensor will give vignetting effects.
