Using this connection FoCal is able to operate the camera remotely, driving it to capture test images, download those images and analyse them for sharpness and detail in real time.
Included with each FoCal Pro purchase is the licence key to use FoCal Pro with supported cameras on both Windows and Mac operating systems.įoCal runs on your computer and connects to the camera using a USB cable (supplied with cameras). FoCal Pro from Reikan is purpose designed to provide a comprehensive and accurate way to focus calibrate and test most modern Canon and Nikon DSLR cameras and lenses.
