Lens image circle size

Further research on camera lenses and image quality indicated that another detail of the lens specification was relevant –  the “lens image circle” needs to be slightly larger than the sensor diagonal to avoid dark corners in the image.

I am therefore noting the sensor size in my Action Camera Comparison Chart, to ensure that any new lens has a sufficient image circle for the sensor.
