FoCal does not display the RGB results by default, but can do so by accessing controls if required. The values are combined with a reading of the total amount of light that is falling onto the target, so that if there is a color shift due to the type of light that is present during the test, this does not skew the results. This measures the horizontal and vertical sharpness in all 3 color channels in RAW images produced by the camera. I ran the test in “Fully Automatic AF Microadjustment Calibration” mode. You do need to be prepared to move the camera and tripod to accommodate different focal lengths, although for underwater use, with mostly wide-angle or macro lenses this is perhaps less of a problem. Printing it at a larger size cured this however. I found that the process was simple and intuitive, although, particularly with long lenses, the recommended A4/US Letter size printed target was too small in the LiveView display to work. A green “tick” mark signifies that the target is in the correct place.

If it is in an incorrect position, it uses arrows to suggest the movement direction to correct this. The utility displays the camera’s LiveView image, and adds “Target search” that identifies and lets the user know that the target is correctly positioned relative to the camera. The first task is to use the Target Setup utility to check that it will work effectively with the test.

Once it locates the camera, it then presents a range of testing options, depending on which version is installed. Once it is all set up, the user is presented with a window asking him or her to “find and connect” with the camera. There is a limit to the number of cameras that can be registered, in order to prevent unauthorized commercial use, although I gather that if you reach the limit, you can request for it to be lifted by Reikan.

When it is plugged in, a licensing screen will pop up, which required you to license each camera that is used with the it. The camera’s eyepiece must be covered/closed and any lens or camera stabilization needs to be disengaged. The camera and its lens need to be installed on a tripod (although a bean bag or alternative would suffice at a pinch) and plugged into the computer that has the program loaded via USB.

The instructions supplied with the software give a good idea of suitable locations. Once installed, the target can be printed off and installed on a convenient surface. The software currently only supports Nikon or Canon cameras. I believe that this can be changed at a later date if required. Once installed and activated, the user need to specify whether it will be used with Nikon or Canon cameras via the preferences. Once installed, it prompts for activation via a key that is supplied via email. It should be noted that it is available in both Windows and Mac versions. Purchase is via download, and if the software is to be used on a Mac, also requires the download and installation of the Mono framework in order to function.

Each is supplied with high resolution pdf and png targets that can be printed off for the tests. The latter two offer an automatic option, with the Pro version offering additional test options and more control of the testing process.

Reikan offer three versions of the program, Standard, Plus and Pro. The software then analyses the images and “chooses” the setting that gives the best results. This uses control software to take control of the camera and shoot a series of images of a calibration target at different AF fine tuning increments while tethered to a computer. Reikan offer a software based solution to autofocus calibration called FoCal. The increments normally take the form of + or - adjustments, on a scale of 20 units either side of 0 or neutral (+20 to -20).

The problem typically is how to go about finding what increment to dial in. Most SLR cameras offer the option of fine tuning the autofocus accuracy somewhere in the menu system. One area that this is perhaps most noticeable in, is the autofocus accuracy. It is a little known fact that most cameras and lenses are all very subtly different, even within the same model, and so will behave (again subtly) differently on different bodies. The advent of super high resolution cameras has forced people to re examine their lenses, both in terms of performance and compatibility.
