You can open MultiTest either from the Camera menu, or from the MultiTest card on the Camera page.
In order to use MultiTest, you need to ensure that the camera and target are set up correctly. Target Setup utility is an automated utility which will help you do this - all the information you need is here.
You can access Target Setup from the Target Setup button on the test footer bar, from Camera menu or from the Camera status page.
Once the setup steps above are complete, you are ready to run MultiTest.
You can start the test with the Start button in the Status tab, or with the Start button on the test footer bar.
The Status tab provides information about how the test is progressing, including an estimated time remaining and estimate time to next user interaction (for User Assisted Mode cameras – see below).
Depending on whether your camera supports Hands Free Mode or User Assisted Mode (see here for the camera support list), you may be prompted periodically to change the AF Microadjustment / Fine Tune of your camera. For detailed information about this, please see here.
The Summary page shows basic results for the MultiTest.
The Test Results Overview card shows a few essential test results. In this case, it shows that the lens is in need of calibration, and shows the number of measurements taken.
The Chart card shows the Quality Grid chart, which shows quality information across the focus and aperture range.
Note that it can take quite some time (50 shots or more) before information is shown on the summary page chart.
The Crops card shows the comparison between the and worst images captured.
You can slide the bar in the crop images left/right to better review the comparison. You can also make the crop card large with the maximise button on the top of the card (this applies to any card which have this button).
Some measurement values are indicated below each side of the crops.
The Test Overview card gives basic information about the test – for example which camera and lens were used.
