This is an important setting to ensure correct operation of tests.įoCal has been developed and tested regularly with a wide range of lenses, and then been through an extensive beta testing program with hundreds of different lenses of all types.ĭuring the testing and development, it was noted that the consistency of the focus with the cheaper and older designed lenses (e.g. NIKON ONLY: The Live View mode in the SHOOTING menu should be set to Tripod (rather than hand-held) if available on the camera (this setting is only available on older Nikon cameras). NIKON ONLY: If available, the camera USB mode in the SETUP menu must be set to PTP/MTP (and NOT Mass Storage) otherwise the camera will not correctly communicate with the computer and FoCal will not be able to connect to the camera. Details of the lighting requirements are discussed in The FoCal Target. It is recommended that the light level on the target is around an EV of 8 (1/30s at f/2.8, ISO100) or above. The minimum light level to run the Fully Automatic test is around an EV of 5 (1/4s at f/2.8, ISO100), but the lighter the environment the more reliable and consistent the AF performance of the camera will be, therefore leading to better results. the Canon 100 f/2.8L IS Macro or the Canon 100-400L IS), please ensure it is set appropriately for the test distance.

If you have a lens with a focus limiter (e.g. If you are using a lens with IS (Image Stabilisation) or equivalent it is recommended that this is switched off.ĭisable Focus Limiter (ensure maximum range) Canon 7D, 7D Mark II, 5D Mark III and 1D X and later), you should choose the normal single point AF mode ( not Spot AF) – the software is not able to validate this and the results may be less accurate if you are in the wrong mode. You must ensure the AF mode is set to ONE SHOT (Canon) or AF-S (Nikon) :ĬANON ONLY: For the cameras which support spot AF (e.g. Failure to observe this requirement may lead to unexpected issues when running tests. Where available on the camera you should ensure that the custom settings do not limit the choice of AE Mode (ensure A/S/M are allowed), or limit the shutter speed, aperture or ISO range. Where possible, settings are verified before running a test and a message will be shown if the camera is not set up appropriately. Camera Setup - Settings Setting up the CameraĪlthough FoCal takes control of the camera there are some settings that cannot be changed from the computer and it’s worth making those changes before running a test.
