Nowadays I am working on a project that consist of Raspicam and several devices in Raspberry pi 3.
According to process, I need to make a clear image for video stream and therefore I am looking for a cheap, modular and compatible lens for RaspiCam.
I just would like to increase 6 cm resolution to 30,40 cm.
Is there any lens for optical zoom with given specifications?( I dont need any professional dslr lenses)
