Field of view is the area that the camera is seeing. For example, if you want to see the whole penny, which has about 19mm diameter, then you need to have 19mm field of view to see the whole penny on the monitor. If you just want to see letter "G" in God, then you need 1mm field of view. If field of view is 4mm, then 1mm size would fill about 25% of the monitor. If you choose a digital microscope with 4mm to 19mm field of view, then you can see the whole penny and also zoom into letter "G".

Working distance is the distance between the front of the lens to the viewing sample to bring the image into focus. For example, 6 inch working distance would offer user the vertical clearance to do some assembly. On some application, shorter working distance maybe desired.
