Not sure if it is the direction you want to head in but Louis Rossmann talks in great detail about the microscopes/ camera combination he uses. One of his videos discussing is here https://youtu.be/C_eQrbop-J4?t=3D95 Majority of his work is SMD . He says hands down it is better to work with proper scope on SMD than using camera-display combo. I dont have any experience here but what he says seems to make sense and sensible.
