Hello,
I am building a drone that can detect a very small target of 2 cm from 2 to 3 meters distance.
I am working with the HQ camera V1 from 2018 and I have a lot a lenses that go with it.
For my scenario, I have calculated the need of a 200mm focal length. (I have also confirmed this number with another (sony) camera. )
The maxim focal length I can reach with my current setup is 48 mm... but I need more. I have tried increasing the distance between the lense and the sensor by adding a spacer, but after a certain point it will not focus anymore.
Does anyone know where I can find a 200mm lens for this camera? or maybe you can think of another solution for problem?
Thank you for your time.
