FoCal Plus from Reikan is purpose designed to provide a comprehensive and accurate way to focus calibrate modern Canon and Nikon DSLR cameras and lenses. Included with each FoCal Plus purchase is the licence key to use FoCal Plus with supported cameras on both Windows and Mac operating systems.
FoCal runs on your computer and connects to the camera using a USB cable (supplied with cameras). 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. FoCal determines the best auto focus calibration value for any attached auto focus compatible lens, setting mirror lockup and de-focusing between each test image. Proprietary image processing and predictive statistical algorithms allow FoCal to calculate the best calibration accurately and easily and with minimal input from the user.
FoCal Plus is able to automate much of the calibration process, as a result auto focus calibration with FoCal is quick, accurate and provides an objective and error free method of lens calibration.
FoCal Plus provides other functions in addition to its core task of auto focus calibration, including:
- Assisted Target Setup – Live View help for getting the target set up correctly.
- Semi Automatic Calibration – automatic control of the camera to simplify you find the best settings.
- Fully Automatic Microadjustment/Fine Tune Calibration – camera/lens calibration at the touch of a button!
- Manual Calibration Mode – calibrate from a set of image files you shot manually.

FoCal Plus will NOT allow calibration of lenses or a combination of lens & teleconverter with an effective focal length longer than 400mm. For this, you will require FoCal Pro.
