I'm trying to get the overall optical magnification of my digital microscope and wondered if the lens built in the Rpicam v2 has any magnification. Does anyone know this specification? Thanks!

There is no information, but here is other info you may found helpful:

crop factor is: 9.406
focal length: 28.6 mm (full frame equivalent).

My personal experience show such lens usually have between 1:5 and 1:10 magnification ration (1 on the lens is 5 on the real object). There is relatively simple way to calculate the magnification: put rules under the microscope, make a photo and calculate the size of object on the sensor and real object size.

Here you can find some of the specs of this module sensor.

  • for that, you have to know the size of the camera sensor
