Supported Cameras

This page gives a complete list of cameras supported by FoCal, cameras not listed are not supported by FoCal (please check the FoCal blog for news on recently released cameras to find out about upcoming FoCal support).

Canon Cameras

The following table shows all Canon cameras supported by FoCal, their available features as well as their FoCal Mode.

Camera FoCal AF Calibration FoCal Mode FoCal Controlled Mirror Lockup*
Canon EOS-1D Mark III Supported Hands Free [?] No
Canon EOS-1Ds Mark III Supported Hands Free [?] No
Canon EOS 1D Mark IV Supported Hands Free [?] Yes
Canon EOS-1D X Supported User Assisted [?] Yes
Canon EOS 5D Mark II Supported Hands Free [?] Yes
Canon EOS 5D Mark III Supported User Assisted [?] Yes
Canon EOS 5DS / 5DS R** Supported User Assisted [?] Yes
Canon EOS 6D Supported Hands Free [?] Yes
Canon EOS 7D Supported Hands Free [?] Yes
Canon EOS 7D Mark II Supported User Assisted [?] Yes
Canon EOS 50D Supported Hands Free [?] Yes
Canon EOS 70D Supported Hands Free [?] Yes

*Mirror Lockup: Where possible FoCal lifts the mirror with a short delay before releasing the shutter to reduce the risk of vibration during image capture.

**EOS 5DS / 5DS R: MultiPoint Focus Test will not work with the EOS 5DS and 5DS R currently. Fully supported and working for automatic focus calibration, focus consistency and other tests with center focus point.

Wide and Tele Calibration: Some Canon cameras have the ability to record two calibration values when used with zoom lenses. This function exists on EOS-1D X, EOS 5D Mark III, EOS 5DS, EOS 5DS R, EOS 6D, EOS 7D Mark II and EOS 70D. If the camera is capable of two calibration values on single lens FoCal is able to use this feature (calibrate each zoom lens twice, once at either zoom extreme and FoCal will adjust the correct setting on the camera).

*Mirror Lockup: Where possible FoCal lifts the mirror with a short delay before releasing the shutter to reduce the risk of vibration during image capture.


User Assisted Mode

FoCal runs on your computer and connects to the camera using a USB cable (supplied in the box with new cameras). Using this connection it is able to operate the camera remotely, driving it to capture test images, download those images and analyse them for sharpness to determine the best AF calibration value for each lens. A series of proprietary image processing and predictive statistical algorithms mean that FoCal is able to calculate the best AF calibration for a particular lens accurately and easily, with minimal input from the user.

Software control of the AF Micro Adjustment (or AF Fine Tune) setting on certain cameras (designated as “User Assisted”) is not possible from a computer. The features that can be controlled are dictated by the camera manufacturer, they expose the ability to adjust certain settings through a documented interface which FoCal uses to make all the necessary automated adjustments to the camera.

What this means in reality is that FoCal provides it’s full automated calibration, determining which and how many AF Fine Tune points are needed for the calibration result. Other things, like setting mirror lockup and de-focusing between each shot, analysis of each image for sharpness / detail and graphs to determine the best AF calibration value work automatically. During the calibration process a number of AF Fine Tune changes need to be set on the camera and they have to be input by the user as directed by FoCal (so it’s “user assisted” in that sense).

We continue to try to get the camera manufacturers to add this software functionality and we’ve got some ideas on how to go about this so it’s not a done deal(!). In the shorter term we’ve worked on making the “user assisted” part of the process easier, fewer AF Fine Tune steps required and “Voice Prompt” along with the camera HotKey mean the process is very quick and simple.

Hands Free Mode

FoCal runs on your computer and connects to the camera using a USB cable (supplied in the box with new cameras). Using this connection it is able to operate the camera remotely, driving it to capture test images, download those images and analyse them for sharpness to determine the best AF calibration value for each lens. A series of proprietary image processing and predictive statistical algorithms mean that FoCal is able to calculate the best AF calibration for a particular lens accurately and easily, with minimal input from the user.

This mode works in a very similar way to User Assisted Mode, with FoCal able to make settings changes on the camera automatically. The difference with this mode, FoCal is also able to automatically change the AF Micro Adjustment / AF Fine Tune setting. Once a FoCal calibration is running the user does not need to input any values and FoCal runs “Hands Free”.

Not Supported by FoCal (Sony / Pentax / Panasonic etc)

FoCal’s support for a wider range of cameras is something we continue to investigate. Both Nikon and Canon make available a software library that FoCal uses to control these cameras. This type of software control is slowly starting to become possible for other cameras and when it does you can be sure we will be looking to extend FoCal to accommodate them.
